    Description

    Unusual rare pure indium rings for mounting optics to mounts that may be water cooled.
    High power lasers utilize indium to mount optics subject to extreme heat.
    These fit loosely around 3/4", 19mm dia. optics as seen in photos.
    Actual measurements are:  OD .868", ID .787", .04" thick
    Not sure of melting temp. But written on the containers they came in said 99.999% pure (containers in photos not original). So whatever pure indium melts at.
    Use a plumb bob or anything cone shaped to reshape them if they "get out of round".
    Sale is for TWO rings, enough for both sides of an optic. There are 12 in the box.
    See my other sale for indium rings for 12.5mm, 1/2" dia. optics.
    I combine ship to keep costs down.
