    Default China laser shop 100 mw red module



    Output Power: 100 mW
    Stability >90%
    Wavelength: 650 nm +/- 5nm
    Spot Mode TEM00
    Operating Voltage 0-5v DC
    Operating Current 25` 150 mA
    Storage Temp -40 degree to 80 degree Celsius
    Case Material Aluminium
    Beam Divergence < 3 mrad
    Beam Diameter at Aperture 4.5-5.0 mm
    Life: About 3000 hrs
    Operating temp: 10-50 degrees C
    Warm up time: <10 ms

    First impressions. (Laserhead)
    First off in my opinion I love this laser head.
    However is was expecting it to be a bit bigger.
    However is does have a lot of positive’s
    1. It’s easy to mount.
    2. it’s not to big but provides more then enough cooling for the diode
    3. And it’s easy to replace the diode in case it ever dies
    Beam specs seem to be around 1 mrad
    And the beam diameter is 4.5 mm
    And there are more than enough mounting holes on the bottom side of the laser head.
    Also it produces a nice round beam



    First impressions. (Driver)
    The driver does look kind of cheap but it does the job perfectly.
    The current for this specific diode was set at 180 mA.
    The blanking input can handle up to 10khz.
    This should be more than enough for most applications.
    Also it has a soft start feature.
    So don’t be worried when your laser does not turn on immediately
    Beam quality is great no distortions or reflections.
    Focus can be changed by turning the lens on the front of the module.
    Mine was slightly out of focus when it arrived.
    Now for the output power
    The module is rated as 100 mw 655 nm
    My first measurement just after power on peaked at 122 mw.
    After 15 minutes I took a other measurement this one came in at 119 mw
    After 1 hour I took a other measurement at this point the module was about 25 degrees.
    And was doing about 127 mw so that’s a free 27 mw not bad for a module In this price range.

    Overall this module seems to perform very well.
    Its output is stable and free of distortions and reflections
    The entire module costs 78 dollars including shipping
    So the price is also very reasonable
    Shipping to Europe took about 1 week
    So overall I would recommend this module to anyone
    Who wants to build a laser projector on a budget.
    Also this module is available in a 200 mw version.
    So it would be possible to combine 2x200 mw modules to say about 350 mw after all the combining optics.
    The only thing that would be needed is a polarized beam combiner / splitter.
    And these can be found on ebay for a couple of dollars
    Hope this review was helpful

    Nice write up ---however, where can you find polarized beam splitters on ebay for a couple of dollars?

    Been there, done that, got the t-shirt & selling it in a garage sale.

    Default re

    looks the exact driver board i had from a green 100mw laser i stripped out of my first laser (a sik s69) i was impressed with it too as a laser diode but in the s69 it was rubbish because it only had stepper motors.
    im not a whiz on electrics so bear with me but be careful not to blow the components at the top of your picture number 1.
    i mean the two black things back to back. dont know what they are. i thought they were capacitors but not sure. any way i blew it up and had to short it to get it to work but i decided that was not too safe so its now sitting in my house gathering dust. id quite like a new drive board as its a great little had held laser when hooked up to a 5v battery.

    I have 2 of their 200mW modules, exactly the same looking as the ones in the pictures, ready to be mounted on a lump of Ally and firing into a PBS cube. I shall be purchasing one of Rob, Stanwax's dual analog driver boards and It's all to replace the horrible 300mW red 650 module - with a beam the size of an elephant, to all be mounted into my RGB

    ^ Hey Ollie, I think you just found a replacement board, perhaps two!
