BICV-FS09 25.4 mm Dia. x -35 mm FL; Uncoated; Double-Concave Lens
The BICV-FS09 is a high-precision double-concave lens, sourced from WTS Photonics, with a diameter of 25.4 mm and a focal length of -35 mm. This lens is designed for use in applications that require a concave-concave spherical lens with a circular base shape.
The lens features an outer diameter of 25.4 mm and a thickness of 7.17 mm at the edge, reducing to 2 mm at the center. The effective focal length (EFL) is -35 mm, making it suitable for use in optical systems where a negative focal length is required. The first radius of curvature (R1) is -32.52 mm, while the second radius of curvature (R2) is 32.52 mm, indicating a double-concave design.
The back focal length (BFL) of this lens is 35.68 mm, and it does not have any coating applied. The material used in the construction of this lens is fused sil mal-1965, a material known for its high transparency and durability.
This lens is designed to work with a wavelength of 546.1 nm, making it suitable for use in a wide range of optical applications. The lens is uncoated, which means it does not have any anti-reflective or other coatings applied to its surfaces. This may result in a higher level of reflection at the lens surfaces, but it can also make the lens more cost-effective.
