    DTR also did a collimation lens comparrision with the ML520G71 @ 638nm. The 405 G 2 provided the least transmission loss. He did NOT test with the Mccarrot lens. Mr. Mcarrot....OK....I have seen your set up B4....looks clean and organized....but....how much for the Mount, LD holders and Collimation Lenses ???? A complete set up....less A-prisms and LD'd....ready to roll ????? And....if I remember correctly.....your lenses are NOT the M9 geometry.....so....the entire assembly need be purchased as a package....I have no issue with this.....but just wanted to clairify. I am not saying...this IS the way to go....but it is a consideration ...depending on cost. Thanx.

    The killer is the price of his lens/carriers @ >60€ a piece (after tax and shipping) and his mount will only work with these due to the bore holes for the lens carrier being 11mm.

    the black tripple block cost 69,- euro, a collimator costs 49,- but I can can give you a set discount.

    the lenses are M9, but the barrel is 11mm.

    The big advantage of using these barrels is you can rotate the barrels so you can get the polarization spot on. And also fitting the diodes or replacing diodes in very easy because you remove the barrel out of the mount.

    The lenses and barrels are the same as the quality collimator Marco sells, so if you can get a better price from Marco feel free to buy from him.

    We made these blocks to make our life easy and get a reasonably affordable quality red and blue.

    We currently use the blocks and collimators to make 500mW 640nm lasers with superb beam specs, and 1W blues in our RGB projectors. Its very easy to assemble and adjust.

    see here for some pictures

    What kind of diode is the 640?

    The standard 642nm 150mW opnext diodes

    So I guess that you're over-driving them just slightly to acheive 500mw at the aperture? That would be 6 diodes for 1 Watt. Not bad for a good beam. I wouldn't look forward to aligning 6 diodes, though. Although it seems easy for some people.. I guess I'm just not one of them ..

    If you keep them cool they run fine on 300-320mA (280mA default)

    Hey Steve-O....would you try the 405 G 2 Collimation lens with the HL6388MG and post the geometry after the prism and at Farfield. If you have a set of Lava Cylinderical optics....I really wonder what they would provide with the HL6388MG ????? Also did you not say the emitter size on the 6388 was 20 uM ??????? I am being a proponent for both the Mitsuibishi and the Optnext solutions !!!.... Perhaps a six (6) multidiode could be done using Cylinderical lenses ??????? See Pic....Yikes...yet another drawing !!!
