G312416331 31.5 mm Dia. UVFS Plano-Convex Lens; EFL=200mm
The G312416331 is a Plano-Convex lens, a type of spherical lens with a single curved surface and a flat surface. This lens boasts a diameter of 31.5 mm and is sourced from Qioptiq Photonics, a renowned vendor in the field of precision optics.
The lens's geometry is characterized by its edge thickness of 2.1 mm and center thickness of 3.3 mm. The effective focal length (EFL) is 200 mm, indicating that the lens can focus light to a point 200 mm away from the curved surface. The radius of curvature (R1) is 101.82 mm, which, combined with the EFL, determines the lens's optical power.
The lens is made from UVFS, a material with a refractive index suitable for use in the ultraviolet spectrum, specifically at a wavelength of 355 nm. This makes the lens ideal for applications involving ultraviolet light.
The lens features a coating on both the front and back surfaces. The coating is Qio AL RALVIS AOI 45, which is designed to enhance the lens's performance by reducing reflection and increasing transmission. This coating is particularly beneficial in applications where high transmittance is required.
