    Default Semrock dichro from last year....

    Has anyone performed testing on these? I have varied results employing the unit I have. I just want to hear from others that have actually placed their dichro into service and a report of the beam quality and appearance....Thanks

    Not yet, but getting close -

    I recently acquired a 640nm I need to combine with a couple of MechEng 660's I acquired some time ago...

    Hi Mike

    I'm using one in my projector for combining a Laserwave 642nm and a dual 660nm MaxyzModule. The person to ask about this is Rob (Stanwax). He did my projector rebuild for me. I know there were quite a few issues regarding the Semrock and it took quite a bit of angle tuning to get it right.

    I'm sure Rob wouldn't mind you PMing him about this.

    Cheers

    Hey Mike -

    Have you had the opportunity to spend any more time working with this dichro?

    I started tinkering with mine this weekend, and it does seem like there are some substantial power losses.
    I'm certainly open to some "tuning" suggestions on how to minimize the losses!!

    Hi Randy

    If I were you i'd PM Rob (Stanwax). He can probably save you a lot of time and effort.
