38-649 25.4mm Dia. x 100mm FL; Laser Grade Plano-Convex Lens Laser V-Coat 266nm

This is a laser grade plano-convex lens, designed and manufactured by Edmund Optics, a renowned optical elements vendor. The lens boasts a diameter of 25.4mm and a focal length of 100mm, making it suitable for a wide range of applications that require precise focusing of light in the ultraviolet spectrum, specifically at the 266nm wavelength.

The lens is made from UVFS material, identified as MAL-1965 in the material database. This material is known for its excellent transmittance and durability in the UV range. The lens features a plano-convex geometry, where one side is flat (plano) and the other side is curved (convex). This design allows for efficient light gathering and focusing.

The lens is coated with Edmund Optics' Laser V-Coat 266nm on both the front and back surfaces. This coating enhances the lens's performance in laser applications, improving its damage threshold and reducing unwanted reflections. The coating also ensures high transmittance at the 266nm wavelength, which is crucial for the lens's intended use.

In terms of dimensions, the lens has a thickness of 2.13mm at the edge and 4mm at the center. The effective focal length (EFL) is 100mm, and the radius of curvature (R1) is 47.61mm. The back focal length (BFL) is 97.32mm, and both the inner and outer radii are 0mm, indicating a circular shape without any additional shaping.

According to the vendor's information, this item is currently in stock, making it readily available for immediate use or integration into optical systems.
