    Default Spiricon LBA-200 Beam Analyzer

    Hi all

    I've just obtained a Spiricon lba-200 Laser Beam Analyser. Unfortunately, there is no beam sensor with the unit.

    Would anyone happen to have a spare sensor unit kicking around that they would be prepared to part with? I'd love to get this working again.

    I could also use a manual if anyone has a copy please.

    Many thanks in advance.

    Just start emailing Spiricon USA and be patient.... They are wonderful on supporting old gear as best as they can. Sensor is usually a high end, rebranded, commercial CCD camera... Often there is a list of applicable cameras in the manual. The idea is to buy a LARGE FORMAT B&W camera with well known and precise pixel sizes... Then have a good pile of high end filter glass ND filters or variable density wheels...

    I've had a LBA 1000 and a LBA-300, and both used a CCD camera putting out NTSC or PAL. .. I'm guessing you might be happy starting with a 1/2" format TM-6 camera by JAI / Pulnix… Preferably the TM-6 or TM-7 version you can build a switchbox to set the shutter speeds with. (Usually 75$ on Ebay) But contact Ophir Spiricon in case I'm guessing wrong...

    Basically it is a specialized frame grabber with some serious math in the software and deep bit depth on the A/D converter... Although they do/did make other types of systems using pyro-electric or rotating sensors.

    In most cases you can move the camera a meter or so, or add an automated moving lens unit and get divergence as well as profile, Gaussian fit, and usually M Squared..

    Don't burn the camera sensor, 007...

    Thanks Steve

    Good information, i'll try emailing them. First thing I need is the manual, I'll then pop a screen on it to see if it fires up. If it looks as though it's showing signs of life I'll then start working on finding a camera.

    It'd be quite cool to get this thing up and running.

    Cheers
