BICV212 25.4 mm Dia. x -300 mm FL; Uncoated; Double-Concave Lens
The BICV212 is a high-precision double-concave lens, 25.4 mm in diameter, and featuring a focal length of -300 mm. This lens is sourced from WTS Photonics, a reputable vendor in the optical industry. The lens is uncoated, providing a clear, unaltered view of the light passing through it.
The lens is designed with a base shape of a circle and has a spherical geometry. The thickness at the edge of the lens is 2.52 mm, while the center thickness is 2 mm. The effective focal length (EFL) is -300 mm, and the radii of curvature are -310.8 mm for the first surface and 310.8 mm for the second surface. The back focal length (BFL) is 299.17 mm.
The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. The lens is designed to operate at a wavelength of 546.1 nm. The inner and outer radii are both 0, indicating a symmetrical design.
This lens is ideal for applications that require a strong converging or diverging lens, such as in imaging systems, beam shaping, or beam expansion. The high-quality material and precise geometry ensure excellent optical performance and durability.
