BICV-FS05 12.7 mm Dia. x -25 mm FL; Uncoated; Double-Concave Lens
The BICV-FS05 is a high-precision double-concave lens, 12.7 mm in diameter, with a focal length of -25 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 a thickness of 3.76 mm at the edge and 2 mm at the center, with an effective focal length (EFL) of -25 mm. The first radius of curvature (R1) is -23.32 mm, while the second radius (R2) is 23.32 mm, contributing to its double-concave structure. The back focal length (BFL) is 25.68 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 the lens does not come with any coating. However, it can be customized upon request. The lens is currently in stock and can be purchased directly from the vendor's website.
