Hey everyone,
I recently got a Power Meter and I measured my 445nm laser output with and without prisms. I have the prisms set up at 56.775 deg just like in zoof's templates.
At 485mW, it put out 405mW. 83.5% transmission.
At 500mW, it put out 420mW. 84.0% transmission.
At 470mW, it put out 400mW. 85.1% transmission.
Not good I got these prisms from Stanwax, and from what I've seen on the forum the lowest recorded loss was 2.5%, and the highest at 8.3%. Does anyone know why I am getting such a high loss?
The laser in question is the one in the middle in these pictures:

Any help or advice is appreciated!
