34-081 50mm Dia. x 200mm FL UV Plano-Convex Lens Laser V-Coat 405nm

The 34-081 is a 50mm diameter, plano-convex lens with a focal length of 200mm, specifically designed for use with a 405nm wavelength. This lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.

The lens is made from fused silica, a material with a high damage threshold and excellent transmission properties in the ultraviolet (UV) region. The plano-convex geometry, where one side is flat and the other is curved, is ideal for applications that require a large working distance or where the object side is unlimited.

The lens features a laser-grade V-coat coating on both the front and back surfaces. This coating is specifically designed to enhance the lens' performance in laser applications, providing high transmission and low reflection at the specified wavelength. The coating also offers excellent environmental stability, ensuring the lens maintains its performance over time.

The 34-081 has a center thickness of 7mm and an edge thickness of 3.53mm, providing rigidity and durability. The inner and outer radii are 0mm, indicating a sharp transition between the flat and curved surfaces. The lens' effective focal length (EFL) is 200mm, and the back focal length (BFL) is 195.19mm.
