This is kind of neat.
We've got a single mode 635 nm that corresponds with the 635 nm, like how the 450 nm single mode blue corresponds with the 445 nm multimode blue.
It's nice to be able to choose between power or beam specs.
Thanks for testing +1
Not much benift going past 200
Hows the beam specs?
That with G1 or 3 element or acrylic?
Are you kidding? Guess you´re too spoiled from the other 638´s?
If we can keep these at very low temperature, with a TEC f.i., they should lase at 633-635nm in SINGLE MODE.
(Very) visible difference next to the LOCs.
I´m damn interested in these
If you want to TEC a multimode 635, you'll get some interesting results, or for that matter, if you TEC one of the 180mW single mode reds from Mitsubishi, it will be REALLY awesome.
No, I'm serious.
When you consider that they're ~$60, and for somewhere around $100 we should be able to get the versions that do almost twice as much current, it just doesn't make a lot of sense to me.
It's really not going to be as bright as we can push a LOC.
So sure, if you want to TEC it, maybe you can keep it at 633. But that argument makes a lot of less exciting diodes cooler
I guess my point is -
Sure, you could make this diode cool by TECing it. But for the price and complication of TECing a build, you'd be a million times further ahead to spend the extra $50 and get the better version that will give you superior results without the complexity or expense of a TEC build.
