This is a smaller diameter 10x Beam expander I used a lot with 532nm Optotronics RPL500. Since I do not have specs more than whats written on the original wooden box shown on photos, and I have no use for it anymore, it can be yours. Entrance aperture 5mm Exit aperture 22mm contact me if...

As I promised, am starting a new thread on this subject because i'll have a lot of stuff to post and don't want to pollute other threads. I now have mostly OPT Lasers lenses, but will try others if I get them to compare. I gotta say that guys at OPT Lasers have been super friendly and happy...

I'm selling my Prtable LaserCheck by Coherent. Its served me plenty, and its a nice unit to have if you own few lasers 1W and below. The only bad thing about it is that it is not calibrated for blue and violet lasers well, so for 445nm laser you need to use 421 setting. It is not good for...

anyone interested? Not sure if they are still available.. I don't quite remember but I think $25 a piece was the original price. Just trying to sell them and get the money back :-) Never used, still in anti static bag. the rest of the things on the picture are also brand new (still in a...

I never ended up finding time to build anymore smaller lasers, so its your chance guys to get brand new unused parts at a discounted price. Drivers have never been used, and have been kept in antu static bags. Diodes have never been opened out of sealed anty static bag since i received them...

I'm finally selling my RPL-425. It has about 60-70minutes of use over the 4 year period. Never longer than 5min of On time at the time. It is in pristine condition, and it has been mainly sitting in its original box. I occasionally tested the output, and it has not changed since i first got...

STINGRAY-3 Review " The Hercules Killer" Finally done. version 1.0 :-) The main reason I built this thing was to keep upgrading it :-) Oh ye, also to beat the only other active fan cooled hand held laser in power, and make it smaller! For that, and to keep that up, it had to be...

Can anyone post pdf of DrLava's older version (Flex V4) driver. I have one, but i forgot what points to jump to set it for higher current output. thanks in advance.

Today I tested some 650nm and 445nm diodes with Groove 2, and DrLava's V5 but i forgot to change setting on my DC power supply since i switched from Groove 2 driver. So setting was still at 8V ! I completely forgot that V5 manual states that it should not get more than 5.8V input. Thats what...

Hi guys. I'm about to order one or two of these sleds, but i don't see it as a popular diode. Is there any more experience with this sled 405nm diode of performance other than Morgan's input from the graph in sticky thread? I'm curious weather its safe to push them with to 500mA as other 12x...

I don't see anyone using or talking of Groove 2 driver by Dr.Lava. http://www.*****************.com/shop/77-groove-2-driver.html http://hacylon.case.edu/ebay/laser_diode/Groove_2.php It is linear driver - I think perfect for all our favorite diodes up to 500mA, (405nm, 655nm, 445nm) using two...

Every 2-3 months i check Amazon.com, and for the lest two years (at least) nothing has changed as far as legality and availability of high powered Class-3B lasers (except price that went down :-) so, I ask you.. why do you think FDA lets me buy 10mW-250mW (ten different styles of pointers)...
