    Description

    THG (Third Harmonic Generation) LBO crystal with 1/2 the Crystal life left. Crystal is 4.0mm tall, 3.5mm wide, and about an inch long.
    This one has a damaged area that covers about 50% of the usable area. This one should be able to handle around 50 or so burns so about 5000 hours left.
    The tiny burns are normal for this type of crystal and these are designed to be "shifted" to a clean spot on the crystal every 100 hours or so. This is done by moving the crystal oven less than 1/10mm in the desired direction eventually covering the whole crystal face in a dot matrix pattern. (close up of crystal with 32 "hits" is on a similar crystal).
    Comes in the oven shown. Oven has two cylinder heaters and 10K thermistor. Heaters are typically run in series.
