Precision threaded surface (0.3 mm pitch) concentrates light efficiently for solar condensation, LED beam modeling and stage light adjustment. High optical clarity PMMA with 92% transmittance ensures bright and sharp projection and magnified observation of the finest details. The ultra-thin 2mm profile and 40x40mm square device easily fit into custom mounts, projector bays or experimental setups. Versatile focal length options (1.575/1969/70mm) allow flexible adjustment of beam angle and output distance for various optical projects. Durable acrylic construction withstands temperatures from -40 °F to +176 °F, suitable for repeated use in laboratory and prototype development.
