This is a PLCC-50.8-154.5-UV 50.8 mm Dia. UVFS Laser Grade Plano-Concave Lens, a high-quality optical component designed for use in laser applications. The lens is sourced from CVI Laser Optics, a reputable vendor known for their precision optical elements.
The lens is a Spherical Lens of the Plano-Concave type, featuring a base shape that is circular. The geometry of the lens includes a diameter of 50.8 mm, a center thickness of 6.2 mm, and an effective focal length (EFL) of -300 mm. The concave radius (R1) is -154.5 mm, while the inner and outer radii are both 0 mm.
The lens is made from UVFS material, specifically identified as MAL-1965 in the Material ID. This material is well-suited for use in ultraviolet (UV) applications due to its transparency in this region of the spectrum. The wavelength for this lens is 588 nm.
Notably, this lens is uncoated. Coatings are often applied to optical elements to enhance their performance by reducing reflections, increasing transmission, or providing other benefits. However, in some applications, an uncoated lens may be preferred or necessary.
The lens is in stock and available for immediate purchase. More detailed information about this lens, including technical specifications and performance data, can be found in the vendor's catalog, which is linked in the item data.
