5mw 650nm red Customers Reviews

  • Good while it lasts

    posted by ExtremeMax

    2 colors, great plus. Usefull to point on screens (some screens do not show the red well).
    If it's going to last only one year, 20$ is a lot.There does not seem to be any way to dismantle it for repairs w/o damage.
    Will probably buy another and leave it in its case or transport it less.
  • Great laser for diy and more...

    posted by digicon

    Overall a nice laser product pact in metal casing. Along with the laser there is a cross line manual focusing plastic optic and a spring. The cross line pattern can be adjusted from about 3 cm to many meters which makes it a great product for many uses. The pattern is bright and by focusing the laser line projected is no more than 1-2 mm wide. Also the laser is capable to continuously operate for a long time of period.Easy driven from 2.5VDC - 6VDCHere are some measurements2.5V / 24mA3.0V / 19mA3.5V - 6V / 15mA
    none
    definitely worth to buy!
  • The diodes are just as normal red laser diodes. Good price for what you get

    posted by yuval12321

    Those diodes are good primarily for checking red laser diode drivers before installing an expensive red laser diode. I'm only a begginer in building lasers so I can say that it helped me to build some 100mW lasers and also some 200mW lasers.The price is relatively low for what you get.
    You have nothing to lose if you buy it, the price is very low so you can afford to buy this and test it yourself.
    I very recommend for begginer laser builders to buy those diodes for learning how to build lasers.
  • Accurately made thing.

    Complete set. In total that is necessary is available. Good fine tuning.It is established on a pneumatic gun. Fixed on a trunk weighting compound. On fastening going in a set it is possible to organize a lamp (easy to pick up the size) anything ???????? it is not necessary.
    there is no fastening "larkspur"
    about the spent money I am not sorry. I recommend.
  • ATTENTION Be careful not to stare into beam.

    posted by AlekseyEnergo

    Full description.Does not get hot during operation.Powerful beam.Miniature.
    Point diameter of 3-4 mm. But because of poor focus is on the point of a small areolas, a lens can not qualitatively
    Beam rather moschny whatever long distance and strong illumination would be visible. In Device SKU: 29079, it is weaker. I bought the sample, and to test that you can do with it. The laser itself ustravivaet me, and small size, and a small voltage and current consumption (~ 25 mA).ATTENTIONBe careful not to stare into beam.
