  • Nice modules for DIY projects too

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:

    Modules work perfectly well on standard 5V supplies. The manual focus lens is of decent quality (though plastic), and easily adjusted.

    Output looks like a good 5 mW to me, though 650 is not as visible as 635 nm available in some cheap lasers.

    Cons:

    There is some white silicone compound inside that makes removing the 5 mW diode for experiments a bit tedious - but still well doable.

    OtherThoughts:

    It is not hard to fit these modules with another laser diode (such as from a dvd burner). The adjustable optics and metal case makes them a good choice for laser enthousiasts.

    Bottomline:

    Recommended for use as-is as well as experiments.
