Default O-Like Power Rock Green Torch




Hi, I am new to Laserpointerforums, a great learning tool. I bought a 100mw Power Rock Torch from O-Like and love it. Its waterproof so it has two o-rings on each end, both ends are smooth to turn, focusing is easy. The laser is very solid and well made with a rubber covered button. My only problem with O-Like is that they don’t give enough technical information about their products. I like lasers and wanted to know what type of internal workings it had. Through several emails with Susie, I found that it had an 808nm diode but no IR filter. At this point I was not able to get the laser module out. I needed to know if it had an IR problem, so I did the test shown in “NIST Technical Note 1668, A Green Laser Pointer Hazard”. The test was simple but I saw no IR. I thought DPSS lasers had IR problems. I finally got the module out and was very happy to see the MCA (Multiple Crystal Assembly). The laser module looked well made, thanks O-Like. I did the remote control trick to check for IR filters in the optics and found none. Then I took 4 pieces of exposed 35mm film (the end that’s really dark). They will not pass 532nm green but will pass IR (test it with your TV remote). Using an IR non-filtered digital camera, I was able to see the IR. It was surprisingly low, that could be why I did not see it in my first test.
My last test was for power levels using the HLPM ll Hobbyist Laser Power Meter from Bauer-ee.com. Great for under 200mw.
The laser measures between 95mw and 110mw at 532nm and the IR was < .5mw. And yes I used safety glasses I got from Survivallaserusa.com (Eagle Pair). The bottom line is that Susie at O-like was very helpful and I would buy from them again. From what I’ve read I should have had higher levels of IR. Could high IR be attributed to leakage problems from poor assembly? I also bought a couple of green Panasonic 3400mAh 18650 Li-ion Battery Cell NCR18650B batteries from orbtonic.com. They are in Florida so they came quickly. You have to buy two at $12.99 each. These last a long time compared to the ones from O-Like (blue Li-18650 JYD BO12I). I like the host a lot and would like to try different modules in it. Happy lasering!

Nice review. Pictures are great to add as well. Also if you don't mind waiting you can get those cells from fasttect.com 2 for $17 and free shipping which is a steal.
