BICV-FS26 38 mm Dia. x -1000 mm FL; Uncoated; Double-Concave Lens
The BICV-FS26 is a high-precision double-concave lens, sourced from WTS Photonics, with a diameter of 38 mm and a focal length of -1000 mm. This lens is designed for use in applications where a strong negative focal length is required. The lens is uncoated, which means it does not have any additional layers to protect the surface or modify its optical properties.
The lens is made from fused silica, specifically from the material ID mal-1965. This material is known for its excellent optical properties, including high transparency across a wide range of wavelengths, making it suitable for use in various optical systems. The lens's geometry is spherical, with a double-concave shape. The radii of curvature for the first and second surfaces are -920.64 mm and 920.64 mm, respectively.
The lens's edge thickness is 3.39 mm, while the center thickness is 3 mm. The back focal length (BFL) is 1001.04 mm, and the effective focal length (EFL) is -1000 mm. The lens's inner and outer radii are both 0, indicating that the lens has a uniform curvature across its entire surface.
