    Description

    Here is a clean tested Coherent Spectrum Analyzer system for narrow band lasers in the 550nm to 650 nm range. The free spectral range (FSR) is 1.5 GHz and the finesse (F) is around 200 making this ideal for Helium Neon lasers (543 nm, 633 nm, 594 nm, 605 nm,  612 nm, 640 nm) as well as DPSS 640 nm and 660 nm SLM lasers. Check your red lasers for linewidth! Is that red diode laser really SLM? Find out! The useable range may extend slightly beyond specs with slightly reduced resolution.....say 540 to 660 nm or so.
    System
    includes head
    with
    photodiode, heavy Coherent  / Tropel mount with pan / tilt, cables and tested Coherent controller- just add any working
    oscilloscope.
    Pictures
    are taken with a Coherent 200 single frequency HeNe laser as the source available
    separately
    in my listings-nice older laser working fine.
    Note that the test beam should be
    attenuated
    before entering the head to around 2 mW max.
