CCD and laserlight
Hello Highdef experts,
I'm planning a studioshoot where a laserlight and a fogmachine will be the backdrop of a presenter. The laser might regularly point straight into the lens. Do you think this could do any damage to the CCD's? I hope not. Eelco.

Laser
I have been on a shoot where a Digibeta took a direct hit straight down the barrel and the CCD was ruined. Be very careful!

After going through the operation manual i also found that this is a dangerous thing. We'll skip the idea. Eelco.

I shot once infront of of a high powered laser designed for burning text or images into metal and other objects, I made sure there was a special piece of plastic that filters out any harmful light. The only problem with this is it is green (or what ever color the laser is). Yeah...lasers can really mess with your camera

What about using a half-lucident mirror (like used in teleprompters) ?
Would that help? Otherwise: Get in contact with the laser company - perhaps there is a way to define a lower limit that the laser cant underrun - your safety area... ULI |

You have to completely darken the room to see the laser. The effect is pretty cool, i've shot a short test and that looked great, especially in 25p due to the longer shuttertime. Nothing damaged sofar, but I wouldn't take more risk, even with a glasscreen (or the ND of the cam itself). Thanks for the advice!

Hi
I also meant the vertical axis the laser is pogrammed to. If they can provide a minimum height not to underrun, you´re much safer. uli |
