BICV-FS25 38 mm Dia. x -750 mm FL; Uncoated; Double-Concave Lens

The BICV-FS25 is a high-precision double-concave lens, 38 mm in diameter, with a focal length of -750 mm, sourced from WTS Photonics. This lens is uncoated and features a double-concave design, making it suitable for a wide range of applications.

The lens's geometry is characterized by its diameter, thickness, and radii. The diameter measures 38 mm, while the edge thickness is 3.52 mm and the center thickness is 3 mm. The first radius of curvature (R1) is -690.59 mm, and the second radius (R2) is 690.59 mm. The back focal length (BFL) is 751.02 mm, and the effective focal length (EFL) is -750 mm. The lens's inner and outer radii are both 0 mm.

The lens is made from fused silica (mal-1965), a material known for its excellent optical properties, including high transparency and resistance to thermal shock. The wavelength for this lens is 546.1 nm.

Please note that this lens is uncoated. Coatings can be applied to lenses to enhance their performance in specific applications, such as reducing reflection, increasing transmission, or providing environmental protection. However, this lens has been left uncoated for applications where such enhancements are not required or desired.
