Photos of shutters and iris from pre_m262 BS01cfg007: Possible iris part number is Thorlabs SM05D5D, where "05" is for the 1/2 inch barrel parts (link: https://www.thorlabs.com/thorproduct.cfm?partnumber=SM05D5D). The best photo of the iris from pre-M262 BS01 is 2017-02-07_BS01cfg006_09.JPG. Photos of the the shutters that Sean crimped electrical connectors are also included below. Mike says "I don't know exactly what the part number is, other than the handwritting on the box = "DSS Shutter". It looks like someone etched a S/N on each shutter, so those will need to be discovered for M261 & M262! ". Below are some photos of the shutter, and a shutter block, and the opto-mechanical connection to the iris.
