I have tested a number of digital cameras for I/R and U/V sensitivity, and the results vary enormously. In general, many "compact" types have good infra red sensitivity, but very few have U/V capabilities, due to filters over the CCDs. I have not tried "scan backs". You can put an 87A filter over the lens, and preview the image on the LCD screen. You will need to be able to manually focus to take into account the infra red focus shift. I can't see that there is any danger of damaging the chips.

Has anyone had any experience of using digital cameras with ultra violet or infra red techniques? Would either of these wavelengths damage the camera chip or not be recognised? If the former, were the results any good and were there any special techniques used to enhance the final image? ************************************************************* This message and any files transmitted with it are confidential and are intended solely for the use of the individual to whom they are addressed.
