I saw these on o-like's site, and they looked decent so I thought I'd try one out.. The end result: I'm HIGHLY impressed.
*I'm writing this while on a break from work, so pictures will have to be posted later.
The package arrived in about 4 days (I used EMS for shipping). It was EXTREMELY well packaged and survived the trip in perfect condition.
The power supply accepts 90-240VAC but it doesn't come with a wall plug, so I just soldered a lamp cord on it for testing purposes.
The beam exits the aperture with a 1mm diameter (which is smaller than the specs state) and the divergence I estimate to be around 1.5-1.8 mrad, (which is more than the specs state). These units are IR filtered.
The actual power output is anywhere between 150-175mW depending on ambient temperature, (these are estimated power readings using a laserbee power sensor. Unfortunately this is the only laser power meter I have right now, as my trusty LaserCheck broke some time ago.) so that's a nice bonus.. (I don't have power vs. time graphing ability, so that will have to be done by someone else sometime.)
The unit handles modulation very well once it warms up (a 10min warmup is recommended) and remains very stable at all modulation frequencies. The driver is rated to provide TTL modulation capability up to 10kHz, which it did with no difficulty.
All told, I highly recommend these units as they are very high-quality for $126USD plus shipping. The build quality is extremely good, making these units an ideal cost effective solution for a scanner, or just for fun.
My only complaint is that the listed specs are not correct. The beam diameter and divergence are both incorrect.
Will post pics by tomorrow.
