content: Let alone the electronic and optical parts, looking at those so many custom machined aluminium blocks alone is quite scary when thinking about it's production cost.

content: really interesting item there & love the engineering involvedshame the pump diode died in that laser, but green lasers are not hard to come by now. The argon and the yellow hene are nice though, there is something about glassware that makes things look so cool!looking forward to seeing the acoustic filtering stuff

content: Quote from: AF6LJ on March 10, 2016, 02:19:32 pmMy guess is that Leica for their camera & optical business have ample CNC capability. With low prouction numbers CNC machining a couple extra bits is most likely the most cost effective approach.German Maschinenbau at its very best!

content: Having watched Mike's teardown of the Leica with fascination I remembered I tore down one of these Melles Griot HeNe lasers like 5 years back.The actual laser tube is fitted in an aluminium tube with some thermoplastic gooey. Getting the tube out therefore involved sticking the whole thing in the kitchen oven (..I wasn't married at the time..) to melt it down. Bit of a stink but he..The whole procedure is documented in fotos and videos athttps://wkb.home.xs4all.nl/Laser-hacking/The videos show the defective tube. I was told by a laser guru (the author of the LaserFAQ btw) that the tube exhibits heavy sputtering which is the reason it never starts.
