TECHSPEC® Multi-Element Spacer Rings and Spacer Tubes provide an easy method for controlling optical spacing within TECHSPEC® Multi-Element Outer Tubes. Utilizing different combinations of ring and tube thicknesses provides for creating the optimal optical spacing for your application. These spacing elements feature a dull black coating to reduce unwanted internal stray light. TECHSPEC® Multi-Element Spacer Rings and Spacer Tubes are an essential component for any optical system requiring precision spacing of optical elements. Spacer Tubes with a thickness of 10mm or more have an internal baffle thread for a highly anti-reflective effect, further reducing undesired stray light.
