Laser Safety Dilemma	16 Apr 2005 22:42 GMT	1
10 years ago, my retinas became detached in a road traffic accident. I have lost a little of my central vision in one eye. This doesnt affect everyday life.
Very Powerful Green Laser Pointer	16 Apr 2005 15:23 GMT	4
This extremely powerful Green Laser Pointer is visible over 2 miles away. Its perfect for pointing at starts and planets. The green beam is actually visible through the air. www.GreenLazer.com
T-bar diode SP	16 Apr 2005 13:19 GMT	1
I'd like to know if anyone out there knows the exact emitter distance of the laser diode of a t-bar module from spectra-physics. These are used in a T-80 lasersystem with b-head.
What is this?	16 Apr 2005 12:54 GMT	1
Anyone have any idea of what this is? It looks like there's some sort of objectives on it. Is it worth more than than $99.00? http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem&category=26411&item=7507690671&rd=1
Kodak MDS 100 Camera	16 Apr 2005 06:49 GMT	3
I discovered Kodak no longer supports this optical microscopy tool. I upgraded to WinXP Pro. Kodak software will not interface with XP. Is there a workaround? There is nothing broken on the hardware side of the camera.

Sellmeier coeff. for Schott F2	14 Apr 2005 19:30 GMT	15
I am searching for the Sellmeier coeff. or the refracting index for the Schott F2 glas in the range from 1000nm to 2500nm. I have to calculate the angle in a 30° prisma. Thankx Peter
Help collimating 2W DPSS system	14 Apr 2005 19:20 GMT	1
I've got a ~2W DPSS laser system here that I'd like to use in a projector. It works great, but has terrible divergence. I know I could use a telescope to increase the beam size and reduce the divergence, but I'd like to try and keep the beam <3mm so I can use a set of Cambridge ...
Siemens LGK-7638 Ne-Ne	14 Apr 2005 17:53 GMT	17
Hi brothers of the Light! :-) someone know if this Laser (Siemens\Lasos) is polarized? I can use it for holography?
Microlenses in CCD	14 Apr 2005 17:43 GMT	4
Hi, All There're CCDs with and without microlensing array. Microlensing improves Qeff by the factor of 5-10. Does microlensing influence any way on image quality (MTF, Encircled energy)
Naturally occurring lasers discovered in stars	14 Apr 2005 16:04 GMT	1
Naturally occurring lasers discovered in stars http://laserstars.org Very strong stellar winds can produce plasma recombination lasers. Rapidly cooling hot plasmas can generate a population inversion.
