Alc/omnichrome Optics For Sale

[mixedgas]

I have 5 sets of used 7mm argon optics surplus to my needs, these are
multiline enhanced violet optics, typically 60 cm radius. 20$ a set.
These work in both ALC/omnichrome

I also have 3 brand new KR output couplers, for small frame Kr, supports 647 and 676, 15 mm diameter. 30$ each.

one blue/green polarizing cube, 1/2 size, used to combine two 1.5 watt argons in a semiconductor inspection machine, mounted on ~2" tall post with a small amount of flexure tip/tilt adjustment. covers 488 to 532 with high throughput , but no red.
50$.

I'm interested in the ALC optics. Do you know if they're multi-mode?

60cm oc will give you a multimode , but these are enhanced blue violet, they will not boost the green as they have a bit lower transmission at 514, So if your looking for a 225 mW green screamer these may not be your thing. If you want a lot of blue/violet, these are a nice set. The HR however will support the green, so your halfway there. If you have a single line 60X these are a riot, or if your just looking for a spare pair etc. For a lot of people who have a rebuilt head with narrow beam TEM optics for a lab instrument, these are a decent upgrade.

Sorry, I've been offline for a little while.

I'd say it's worth the experiment. PM me where to send the money.
