DescriptionProduct DescriptionEnd cap diameters: 30.5 mm / 58 mm, compatible with SM1 and SM2 threads respectivelyThreads: SM1 (1.035-40) male thread, SM2 (2.035-40) male threadEnd cap: black anodized aluminumSurface marked with target crosshairs for rough alignmentSeals the end of SM1/SM2 internally threaded lens tubesUsed on 30 mm cage cubes to block side light sourcesThe end caps are made of black anodized aluminum and seal Ø1 in / Ø2 in lens tubes. The CSL-P series features SM1 (1.035-40) and SM2 (2.035-40) male threads for closing the ends of SM-series internally threaded lens tubes. The target crosshairs enable quick rough alignment; for precision alignment, please refer to our alignment plates.Technical Description(1) Threads: SM1 (1.035-40) male thread; SM2 (2.035-40) male thread. Compatible with SM-threaded products and lens tube series.(2) Surface marked with target crosshairs for quick rough alignment. For precision alignment tools, please see our alignment plates. AssemblyApplication ExamplesOeabt offers a range of anodized aluminum SM-threaded end caps and plugs for Ø1 in and Ø2 in lens tubes and cage coaxial systems. End caps are ideal for sealing lens tube systems to safely store optical components during transport or storage, blocking unwanted light and dust.These caps and plugs feature a center dimple mark for easy alignment with the optical axis of the lens tube when machining custom-sized center holes, making them useful for fabricating user-customized inserts.Engineering DrawingsCSL-P Engineering Drawing
