88-993 20.0mm Dia. x 70.0mm FL; Plano-Convex Lens Laser V-Coat 532nm
The 88-993 is a Plano-Convex spherical lens, characterized by its circular base shape and a diameter of 20.0mm. This lens is designed with a long focal length of 70.0mm, making it suitable for applications that require a high degree of magnification or precision. The lens has a thickness of 1.59mm at the edge and 3.0mm at the center, providing a robust structure while maintaining a sleek profile.
The lens is fabricated from N-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. This material is particularly suitable for applications in the visible spectrum, such as laser systems and metrology. The lens is coated with Edmund Optics Laser V-Coat 532, a broadband anti-reflection coating specifically designed for the 532nm wavelength. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, thereby improving the overall efficiency and quality of the optical system.
The item data also provides the effective focal length (EFL) of the lens, which is 70.0mm, and the back focal length (BFL) of 68.03mm. The inner and outer radii are both 0, indicating a symmetrical lens design. This lens is a valuable addition to any optical system that requires a high-quality, precision lens with a long focal length and specific coating for the 532nm wavelength.
