88-162 12.5mm Dia. x 50mm FL Calcium Fluoride PCX Lens Uncoated
The 88-162 is a plano-convex spherical lens, sourced from Edmund Optics, with a diameter of 12.5mm and a focal length of 50mm. This lens is made of Calcium Fluoride (CaF2) with the Mal-1963 material ID, specifically designed for use at a wavelength of 266nm.
The lens's geometry includes an edge thickness of 1.14mm and a center thickness of 2mm. The inner and outer radii are both 0mm, indicating a uniform curvature. The back focal length (BFL) is 48.63mm, and the effective focal length (EFL) is 50mm, which is the distance over which the lens will focus a parallel beam of light.
The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. This could make it more susceptible to environmental factors such as dust, moisture, and scratches, but it may also reduce unwanted reflections and improve light transmission.
