    Size: 85x25mm
    Material: anodized aluminum (light grey)
    Height: 5mm
    TEC: 18.8W TEtechnology DATASHEET
    Temperature sensor: Vishay 10k foil NTC
    Price: 49€

    This adapter can be used with our LDM-C modules without own cooling.
    Adapter and diode mount (TEC cooled) can also be used together for deeper cooling (stacked TECs).

    PM me for ordering.

    Must resist the temptation since I don't do anything with all the bits and bobs I have already but... it's pretty!

ID:	50558 Can't see any sign of thermal insulation anywhere ...does this mean there is a tiny air gap between module and mounting table ?
    If so ...a torque value/setting for clamp bolts might be a good idea !
    Cheers
    PS. I know stainless steel bolts are not very thermally conductive ... but a direct "short circuit" , no top hat insulators...is this really a good idea?

    Exactly, there is a small air gap of 0.2mm.
    Bolts are absolutely no problem. The effective contact area from bolt to module is very small and the heat transmission between bolt and optical table is very low and does not effect the cooling.

    These look nice. I am confused though, I can see a thermal path between hot and cold sides... a thermal short circuit to to speak.

    There is no "thermal short circuit".
    When a module with TEC is mounted on a heatsink or optical table there is a gap of about 0.2mm and it works very well.

    Modules without TEC mounted on the adapter have the same gap of 0.2mm.

    In TEC stacked setup (adapter and modules with TEC) the gap between the thermal sides is 0.4mm.

    Very sexy....
    Am I correct in understanding that the TEC protudes out of the bottom
    of the heatsink by 0.2mm and therefore the heatsink does not touch the
    mounting base directly??

    Ok, understood. Air at those distances will transfer heat still. Surely some capton tape to insulate adjacent surfaces would help?
