apparently they can be used as clock calibration standard and direct energy weapon. :worthy:

I also like the myth that one laser goggle can protect you against just any laser. Believe it or not, but I've even met some high level scientists believing that. :thinking:

Thanks... it's a working process, when i've got some time.

Hi c0ldshadow, i've included a link to LPF on the blogroll of my website, you can see it at: http://optical-technologies.info/ All are welcome to go and have a look

Hi Uvex/laservision products tend to be good quality, and they are generally well on top of laser safety legislation. Regarding the 190-532nm rating, it means the filter has been tested with a laser centred at 532, so a 532nm DPSS should be fully covered despite its linewidth extends a...

Hi primary.Sequence, you way want to try > those guys <, they tend to be pretty cheap and quite extensive. To see the beam you'd need alignment goggles. However, $19 is probably too low. I'd imagine at least 3 time this amount... But you can't take your vision lightly. Follow lasersbee's...

Hi Eku, is the floater due to laser burn? I've got some floaters ever since I can recall, certainly not due to laser. It appears like little darker shadows on everything I can see. I can see light through them but they distort the images. You can see how it would affect your vision > here <...

Hi Xer0, funny you mention that, I am occasionally thinking about something along those lines as well. I've been working in the laser & optics distribution industry for some time, and I often came across Thorlabs as a cheap manufacturer http://www.thorlabs.com. You can find mounts from them...

Despite its low power it finds some application in biochemistry. Some chemicals absorb this specific wavelength. In simple terms, if you know how much optical power a chemical solution absorb, you can easily calculate the concentration of the chemical responsible for that absorption. :P

one of the additional dangers of UV lasers is that due to their photochemical activity, even faint stray light or reflections (on the wall or mounts for instance), can cause damages when exposed to for a few hours: individual exposures in the UV does add up, and a high power short exposure will...
