The Occupational Risks Department in our University came to check the hazards of the confocal microscopes (lasers). They told us to use some kind of glasses (for me when I have to check lasers) and to put a window around the confocal for users protection against lasers. I contacted one company (Lasing), but it is difficult to find something suitable for all the laser lines (range between 405 and 635). There are several kind of glasses and you can buy a few to cover the range. Regarding windows, I only found one that protects between 315 and 540. Can you help me with this? Do you have references I can contact? Thanks in advance for your help.

To join, leave or search the confocal microscopy listserv, go to: http://lists.umn.edu/cgi-bin/wa?A0=confocalmicroscopy ***** You need to make a distinction here between end users and maintainers. From the end user's perspective, you expect that a standard microscope checks out as a Class 1 laser system, i.e. intrinsically safe, with no need to provide additional safety devices. The manual should specify this. Putting it in a black box -- black shields being the only windows that will stop light at all visible wavelengths -- should be superfluous, at least for safety purposes. For people who open the instrument to check or align lasers it is different, as this involves disabling or circumventing safety systems. Then you are working with Class 3 or even Class 4 lasers, and in that case I can understand that OH&S would insist on safety glasses. (AFAIK they should insist on a yearly visit to an ophthalmologist to inspect your retina for damage as well.) It is true that with relatively low power visible lasers (as opposed to the far more dangerous IR lasers) few of the maintenance engineers bother to wear safety glasses. But presumably they are trained in safe working practices; if you are not then safety glasses are a wise precaution. You always need specific glasses that matches the wavelengths (and power!) of the laser you are working with; there is no general solution. Best Regards, Emmanuel -- Emmanuel Gustin, Tel.

To join, leave or search the confocal microscopy listserv, go to: http://lists.umn.edu/cgi-bin/wa?A0=confocalmicroscopy ***** Dear List, Some of our customers have a micro-switch on the door of the lab; which is part of the interlock loop of the laser system. Most, if not all laser systems have a connector for this. But as mentioned before, this is typically for the service / maintenance of the laser system, or used on custom built "open table" set-ups. Yes, safety glasses are wavelength range specific: http://en.wikipedia.org/wiki/Laser_safety#Protective_eyewear Best Regards, R.
