    Default Focusing a Romisen L-B030

    I have an old Romisen L-B030 green laser and I ask if is possible to focus the beam. Even by adding an external lens.

    Edmund Optical offers various lenses, including some for laser collimation.

    Note the variety is large and the prices usually start at the $25-50 a lens level.
    They do have loads of expertise and their people are helpful.
