Thread: Focusing a Romisen L-B030

    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. https://www.edmundoptics.com/optics/optical-lenses/

    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.

    If you can buy the X3 beam expander from Sanwu,do it.I have one and it is very good,as they are the lasers they make.The URL is https://www.sanwulasers.org/.
    You have to communicate first with them to know if it is possible to fit this expander to your laser.
    Look at this as well. http://laserpointerforums.com/f39/fs...ase-93166.html
