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.
