  • 2~5mW Dot Red Laser Module (5-Pack/3V)

    posted by dagabu

    Upon un-packaging I noticed that the all brass construction of the laser head was well milled and bright. It was a pleasant surprise to see that since that means that I can solder plates, tubes, mounting arms etc to them without difficulty. I then hooked up two 1.5V button batteries and tried it out. All five lasers worked great, the point was still fine and not fuzzy at 100m.
    I bought a bunch of A23 batteries and harvested the LR932 batteries from them and soldered the positive to the red wire and the negative of the second battery to the black wire. All I have to do is touch the two batteries together and the laser lights. These will be a lot of fun to use and I intend to mount these on Frisbee's and rockets to track them.
    For a little over $6.00, you really cant go wrong with these.
  • Excellent choice for diode housing

    Has focusable lens.The silver cap piece makes focusing a breeze compared to other modules.Good just as a housing for modding other laser diodes into it.Nice colored dot and bright beam.
    Would get this or sku.5900 again when I need a module depending on the size I need.
    Get it if you need a cheap laser diode module housing.
  • Small and sturdy diode

    Very well built module.Extremely sturdyHas a nice focusable lens.Small so it will easily fit in most projects.Cheap.
    Smaller but more well built than sku.5914Harder to focus though.
    Get this module if you want a small and sturdy laser diode module over sku.5914
  • Nice scope.

    Good, solid construction. Quite heavy.Back-light works fine.Acceptable picture in twilight.Two sets of batteries.Detailed instruction.Strong, large packing.
    Could be cheaper.I dot think that optics is "fully-coated", but it's great deal.
    Good scope for war games, may be hunting.input lens - 40mm;output lens - 24mm;
