Casio M140 diode and prism pairs

[borgqueenx]

works just as beautiful with the new m140 diode

Hey Borg not sure if you are aware of this or not but when referring to these diodes we just use model number and not the projector manufacturers name IE M series, A series, M140, etc.
This is in response to a request made by said manufacturer who prefers their name not be associated with the repurposed diodes.

Weird that they dont want a good word about themselfs.
But editted my post.

Should edit the title as well

They don't want their name mentioned as the lasers can cause damage and they do not want any legal responsibility for damage caused by parts of their products.

Just noticed this thread.. I made a labby with a prism pair and an a130 LD. The positioning
of the prisms can be seen as well, hope this helps

The lens was a 3 element aixiz which I found to give a nice shape. Did not try this
with a 'G' series though.

*LAst pic, top is through the prism pair, beneath is uncorrected, both a 20ft.

Nice build wannaburn!

Hey can you give an estimate of how much output power loss using the prism pair?

I can. Its 350mW. 1.85W with measuring the diode with g2 lens and then 1.5W after.

Thats pretty good!

Btw, where did you get that enclosure from?

 

[yobresal]

Nice correction! Now if only I could find a small enough prism pair to fit inside one of my Ehgemus hosts.

Thanks for the information... :thanks:

Not bad considering the great improvement!

The prisms in my labby build were 808nm AR coated, the loss was huge 30%. Id imagine a
properly coated pair would yield far better results..

The shape turned out much better than what I get with cylindrical optics though.

Ouch.... That's a fairly big loss. What are your prisms coated for?
