strange lens in phr 803t sled

[maxkillz]

I found a little lens in the sled that seems to reflect about 90-95% of the violet light what could that be used for? almost no violet light gets through :-?

Can you see through it?

It's for directing the violet laser in one direction while also letting another wavelength (like the IR or red) to go in the same direction as well. Basically a beam combiner.

yea it's semi clear with some kind of coating on it.

@ rkcstr I see...maybe thats it. it has a violet ish tint to it

So it's just a dichro?

Yup. DVD sleds had one that did this for red.

Whats it look like any pics?

yeah its just a simple dichro

almost all newer sleds have them.

Like a little coated window

heres a pic of it

Yep .. A dichroic mirror for sure..

It's pretty good at splitting a green beam into two fairly equal ones

I will use this to combine magenta with green.

Very interesting combination there... I'd like to see it. ;D

Could this be used to seperate beams? For example, if you used a 650nm dichro with a yellow laser, would you get a red and green beam?

Yeah you could, only if the yellow beam was a combo of red and green though.
