Things I am looking for Radiant X Lpm or equivalent, 400mw rgb setup lab style or projector does not matter, Projectors, 473nm hand held lab style dont matter must be over 10 mw, 532 300 mw lab, 488 nm lab or argon single line, 543 HeNe, working HeNe tubes and psu, 3 watt 445-450, 500 mw 650-670 lab style, Optical Rails, HeCd, 462 diodes, c mount 650 nm diodes, dicro cubes, fog machine, or what ever thanks


for looking V

Bump I am only going to do this once and if nothing sells so be it

remove my posting mods seems no one wants any of it thanks

Did you mean cash as in sending a letter full of cash?

I think money gets stolen a lot at post offices when its sent in envelopes.

Didn't the original post have a diffraction grading? I remember seeing one listed somewhere but no picture

no this is the first time i have offered this grading starlight and silver no all purchases should be done though pay pal thanks

Thanks. Can you post a picture of the gratings and why are they so expensive? I'm looking for more gratings and have one from Dragon Lasers (it is nice glass and was around $15) but avoided buying more from them because shipping was so high.

this is a argon diffraction grading multi line capabilities. and the reason for its expense is two its a large two inch diffraction grading. Second I have seen similar mirrors go for over two hundred on ebay. I have talked to a few members that have expertise in this mirror and what i am asking should be about right for a hobbyist market. New this mirror is around 600 to 800 hundred. this is not just a run of the mill diffraction grating if you need any more questions answered i would be happy to answer them

edit.. Starlight I have only a single diffraction grading at this time my other one was already purchased by another member in a private deal. The only one is the two inch pictured thanks

I have asked or mentioned it twice.....a picture of the grading!

there is a picture of the grading on the very bottom starlight

Wow that think looks think. Will it work with other lasers or just argon stuff?. Also is the pattern a fan or matrix or something else entirely. Thanks and sorry so many questions.

the fan or matrix i will have to ask a friend. I believe it will work with any thing and no problem on the questions. and it is 3/4 of a inch by two inch in diameter. It is really designed for a multi line argon but like I said it would work for anything. it has a slight concave but nothing drastic . this diffraction grating came out of working dna sequencer that i tore down recently. This was one of about a dozen mirrors lens and diffraction's that came out of the assembly. The dna sequencer has a argon laser hence the need for a large diffraction grating.
