89-001 5.0mm Dia. x 20.0mm FL; Plano-Convex Lens Laser V-Coat 633nm

The 89-001 is a 5.0mm diameter, plano-convex spherical lens with a 20.0mm focal length, specifically designed for use with a 633nm wavelength. This lens is sourced from Edmund Optics, a renowned vendor in the optical industry.

The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. The plano-convex geometry, where one side is flat and the other is curved, allows for efficient light gathering and focusing. The lens has a center thickness of 1.5mm and an edge thickness of 1.19mm, providing a robust structure while maintaining a slim profile.

The lens features a laser-optimized V-coat coating on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission at the 633nm wavelength. The coating also provides excellent environmental stability, ensuring the lens maintains its performance even in harsh conditions.

The 89-001 is a versatile lens suitable for various applications, including laser systems, interferometry, and beam shaping. Its high-quality materials, precise geometry, and advanced coating make it a reliable choice for demanding optical applications.
