This adapter screws into a lens ring on the side of a qpod or qpod 2e and adapts readily to SM1 optomechanical components from Thorlabs. The interior of this part is threaded with the Thorlabs standard 1.035″-40 thread to hold 1-inch diameter optical components from simple filters to lens tubes. An internal retaining ring is included. The 1.2” outside diameter will neatly insert into a CP12 – 30mm cage plate, providing access to optical cage systems. A cross section shows optical access to the cuvette, when using this adapter.
