job on earth search this website search privacy policy other ilda websites safety site member site laser show damage to cameras lasers emit concentrated beams of light which can heat up sensitive surfaces like the eye s retina and cause damage camera sensors are in general more susceptible to damage than the human eye for large scale shows such as on a televised concert laser show producers work with clients to avoid tv camera locations and video projectors ilda members see this page for details however it is not possible for laser show producers to be responsible for all cameras and camcorders which might be at a show therefore if you attend a show as an audience member you should take reasonable precautions not to let a laser beam directly enter your camera lens you can photograph the beams in midair or doing graphics on a screen if you can t see the laser source projector output aperture or bounce mirror in your viewfinder this means you re not getting the full beam power into your lens indirect viewing like this should not cause damage avoid beams which are coming straight onto your lens the damage potential is much greater when the entire beam power enters the camera lens eye safety is primary the primary safety concern for laserists is that the show is eye safe a good working definition of eye safe is that everyone leaves the show with the same vision they entered there is no detrimental change to a person s vision international safety standards such as iec 60825 and ansi z136 set maximum permissible exposure levels for laser light shows done at or below the mpe should cause no problem for human eyes even shows which exceed the mpe have remarkably safe records eight documented or claimed eye injuries out of 109 000 000 persons viewing continuous wave laser shows over 30 years however there are no mpes for sensors such as cmos or ccd chips this means a show may be perfectly safe for eyes but could possibly damage a camera sensor one reason is that camera lenses may gather more laser light and concentrate it to a finer point another reason is that a cmos or ccd sensor may be more easily damaged than the eye due to the many varying factors involved with lenses and sensors laser show producers cannot be responsible for audience member damage to cameras or camcorders slr camera and binoculars warning photographers who use an slr or dslr camera should not look through the viewfinder directly towards the laser projector output the camera lens will gather much more light than the human eye this is focused by the mirror in an slr or dslr camera into the viewfinder thus increasing the amount of laser light this is not the case for any camera or camcorder where a person views the image on a screen similarly persons should not use binoculars a telescope or similar optical light gathering devices to view audience scanning lasers types of damage the severity of damage can vary widely we have seen cases of minor damage such as small areas of a few pixels which no longer work the pixels are not noticeable unless in an area of uniform color such as a blue sky in more extreme cases there may be larger or more extensive dead pixel areas or there may be burn in of a laser image the damage is readily noticeable in most photos or videos in this case the camera is ruined for quality use this photo shows numerous laser caused spots on an hp photosmart 945 click for a larger view photo courtesy aljaž ogrin damage to one location may result in a horizontal or vertical line in such a case data from the entire row or column of sensors can no longer be read out properly search youtube and other internet sources for videos and pictures of laser caused damage see for example laser light kills canon 5d mark ii or lasers killed my cmos note that not all claims of laser damage are valid in march 2009 we reviewed a case where it was claimed that a fuji f60fd 12 megapixel point and shoot camera was severely damaged by a laser ilda analyzed video from the camera and determined the probable cause to be a very bright white light in another case this youtube video shows a standard camera flash speedlight causing severe damage to a ccd sensor in an instant for more information a webpage called analysis of laser light threat to cctv gives a good general overview of what power ranges and usage patterns might damage camera sensors sacha casken s masters thesis describes laboratory experiments on how consumer point and shoot cameras were damaged by blue green and red laser beams an excerpt from his thesis is here a march 2017 article in the journal optical engineering looked at laser damage to cmos and ccd sensors and to digital micromirror devices dmds used in video projectors a summary is below blue button of the damage threshold to these sensors and devices more information on laser eye safety ilda has presented information about audience scanning laser shows in the scientific paper scanning audiences at laser shows theory practice and a proposal this gives some reasons why even shows which are well above the mpe have not caused any apparent eye changes in millions of audience members some of the reasons may also be relevant to why some camera sensors are damaged while many others are not more information for members ilda members can get more specific information on avoiding camera and video projector damage on this page password required more information on protecting cameras for producers a producer asked ilda if there were any filters available that fit camera lenses to help protect them from laser light see the reply below also below is brief information on a line of epson video projectors that includes a mechanical shutter to protect the lens from laser damage can a filter protect cameras the following was written in response to a video producer who wanted to know if there was a filter that could protect cameras from laser light we are not aware of any such special lens filters made specifically for cameras that will protect a sensor from laser damage there are filters for camera lenses which can reduce the total amount of light coming in in other words the filters darken the entire scene such neutral density or nd filters are widely available unfortunately no one can say without testing how strong an nd filter is needed to stop a particular laser from causing damage to a particular sensor for example nd2 will reduce the light to 50 half of its normal intensity an nd8 filter will reduce it to 12 5 1 8 of its normal intensity an nd8 filter may help but with a powerful laser and a long enough exposure even nd8 may not be sufficient a direct laser beam can also damage or burn through a nd filter since it absorbs light it is possible to purchase glasses goggles and sheets of plastic or glass that can protect against laser light the manufacturer would need to know what specific wavelengths of laser light are being used and at what power in order to provide adequate defense against the laser if the laser is green only then the protective material would block green light of that wavelength this will distort the colors seen by the camera green will be reduced a very high quality filter can knock out only the exact laser wavelength allowing some green to be seen but such a narrow band filter is more expensive if the laser is multi colored then the filter must block red green and blue laser wavelengths obviously this affects many more colors than just a green only filter it is even more expensive finally it still is necessary to know how much the laser light needs to be reduced how much nd in order to protect the sensor without testing the laser and the sensor e g knowing how much laser light damages your sensor this is just a guess my recommendation is to simply make sure that no direct laser beams go into the camera lens or close to the camera lens within an inch or two at closest it is the direct laser beams that will cause sensor damage although damage is also possible if the camera is looking at the laser dot or a laser drawing on a surface and the dot or drawing is very bright keep in mind that accidents can happen in one situation 12 expensive 100 000 barco projectors were on truss the laser operator set the beams during rehearsal so they missed the barco projectors but during the show the truss operator did not lift the projectors to the rehearsal height all 12 barco projectors were damaged through no fault of the laser operator you may want to consider using less expensive cameras for shots where the beams are coming towards the camera you may also want to discuss with the laser operator who will be responsible for sensor damage if it occurs for example if your cameras are at fixed heights on tripods then the laser operator would be responsible for keeping the beams so they cannot enter the camera lens but if the cameras are moving then it becomes the camera operator s responsibility to not be in a known laser beam area projectors with built in laser protection in early 2019 epson introduced two projectors that have a mechanical shutter to protect the lens from laser damage these are the models eb l12000q and eb l20000u ironically these use lasers as the light source for the projector there may be other models from other manufacturers but these two epson models are the first we are aware of from worshipavl and the jakarta post damage thresholds of cmos ccd and dmd devices a march 2017 article in the journal optical engineering looked at laser damage to cmos and ccd sensors and to digital micromirror devices dmds used in video projectors the authors looked at both pulsed lasers and continuous wave lasers since cw lasers are used in audience scanning laser shows we are presenting only the cw laser beam results this graph shows that damage to a color cmos sensor starts at around 40 000 to 60 000 watts per square centimeter for an exposure of 0 25 seconds however a color ccd sensor is more vulnerable damage begins to occur at around 16 000 w cm 2 for 0 25 and 0 1 second exposures black and red lines and at around 9 000 w cm 2 for exposures of 5 and 10 seconds blue and green lines incidentally the authors found that a digital micromirror device dmd commonly used in video projectors had a damage threshold of about 19 000 w cm 2 for comparison a 5 mw laser pointer at a 1 foot distance has an irradiance of 0 374 w cm 2 after magnification by the lens of the eye the same laser s irradiance on the retina is 440 w cm 2 so assuming a camera has a lens with similar magnification as the eye s lens an irradiance of 440 w cm 2 is well below the damage threshold of 40 000 w cm 2 for a cmos sensor or 16 000 w cm 2 for a ccd sensor this assumption may not hold since camera sensors have been known to be damaged by relatively low powered lasers aimed directly into the lens jan 14 2019 corrected cmos text description which was previously off by a factor of 1000 thanks to dominik jan č ik for pointing this out are tattoo lasers similar to laser show lasers no tattoo lasers are pulsed while most laser show lasers and all of those used in regulated audience scanning are continuous wave lasers in march 2019 a video showed laser tattoo removal damaging a high end digital camera sensor just by taking a video of the laser pulses on the skin the laser beam did not directly enter the sony a7sii lens and yet with every tattoo removal pulse of the green laser the camera sensor was ...
