This is the PLCC-25.4-206.6-UV, a Plano-Concave Spherical Lens with a diameter of 25.4 mm, sourced from CVI Laser Optics. The lens is designed for use with a wavelength of 588 nm and is made from UVFS material, specifically identified as UVFS MAL-1965.
The lens's geometry is characterized by its center thickness of 2 mm, a concave inner radius of -206.6 mm, and an effective focal length (EFL) of -400 mm. Notably, it does not have an outer radius or an inner radius, indicating a plano surface on one side.
The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. This could be suitable for applications where specific coating requirements are not necessary.
