    Default 9mm 445nm 2W Laser modules core

    9mm 445nm 2W Laser diode module core, 0.4mrad full angle, 4mm x 2mm near field. Sits on top of a TEC and is part of 6 units for a little home project I am putting together.

    Had to knock up these little modules with a super tight better than usual beam spec to match what I am doing with the 638 Mitsubishi diodes.

    A lot of messing around for a day and a loads of lens combinations later, I got the beam I was looking for.

    And 0.4mrad full angle, 4mm x 2mm near field is real but very hard to reach and even harder to adjust.

    Will post some beam shots when I get all six complete in a few days.

    Looks real nice and small
    Do you want to share the info on the 3 lenses used in
    That setup ?
    When God said “Let there be light” he surely must have meant perfectly coherent light.
