    Question

    Ummm... I am a little slow sometimes. What is the reflection/transmission specs of these? I got a feeling I set my reds up wrong...

    From the info Adam has posted from Semrock, the efficiency quoted by them is around 98% for the reflected 635nm beam, and 96% for the transmitted 660nm beam.

    Cool

    Simon is correct. Aaron, you want the 635 nm beam to be reflected off the surface of the dichro, while the 660 nm beam (from your Maxyz module) passes straight through the dichro.

    Will there be another GB on these do you think?

    Sorry, just read whole thread.

    Hope it's soon

    Cool

    Sorry to hear that, Aaron. Guess you've got a little re-mounting to do then!

    Graham;

    Don't know if there will be another group buy or not. It took nearly a year to get enough interest to do this one, and even so we only just barely made the minimum order of 10 pieces.

    Maybe after people get their hands on these dichros and put them to use, there will be more interest. We'll see I guess.

    Sure, would also be good to see what results you get.

    Will this be a first this has been done?

    Cool

    Don't know if it's a first or not (doubt it), but it's a first for PhotonLexicon at least.

    I just need to say, I hate breadboards... DON"T say it... please. I don't own ANY of that equipment needed for what EVERYONE is going to say. I just needed to state my current hatred for breadboards...
