Thorlabs KS05(/M) Ø 1/2" precision kinematic and 50 similar items

THORLABS Ø12.7 mm Precision Kinematic Mirror Mount, 3 Adjusters, M4 Taps + 0.5" laser filter (broadband?) + base mount Description: a mini precision kinematic mirror mount with a laser filter mounted from a R D lab. closed down. You would need a typical 2mm allen tool (2.0 hexagonal) to move the kinematic screws. It has an unknown high end laser 0.5" filter, seems to me a bandpass filter in the IR range (blue coating/reflection). It is the "most down" placed in the first picture. It allows for left or right hand orientation (you can change it easily). it is a METRIC device with METRIC screws and pitches. Measures: https://www.thorlabs.com/drawings/f57cd140fe311b1f-084FA729-9627-553B-DD6EA3EB8E794D85/KS05_M-AutoCADPDF.pdf Other measures: Base dimensions: 30x33mm. Total height: 46mm. Condition: used but in perfect smooth working order. Like new condition. Lens is glued (seems heat-melting glue) to the mount. There is missing the normal locking screw ("NYLON-TIPPED LOCKING SCREW 2.0mm [5/64in] HEX FOR SECURING OF OPTICS"), which is a normal M4 (metric) allen head grub. I send a metal M4x3 replacement, but it would be a great idea to get some plastic M4x3 grubs (very cheap all over or similar sites) to potencially protect any damage to optics. This means the metal grub works, but if you overtight there is a risk to damage optics... you can also glue a little rubber to the metal screw end and create your own "nylon-tipped" version). You are bidding for just ONE item (the last one in the first picture).
