HO-BVL25-1.2 25mm Dia. N-BK7 Double-Concave Lens; EFL=-30mm Uncoated
This is a HO-BVL25-1.2 Double-Concave Lens, a high-quality optical component sourced from Holmarc Opto-Mechatronics. The lens has a base shape of a circle and is designed for use in spherical optical systems. It is made from N-BK7, a popular optical glass known for its excellent optical properties, including a high Abbe number and low dispersion.
The lens has a diameter of 25mm and a center thickness of 2.5mm. The effective focal length (EFL) of this lens is -30mm, indicating that it is a double-concave lens, which means it diverges light. The first radius of curvature (R1) is -32.532744mm, and the second radius of curvature (R2) is 32.532744mm. The inner and outer radii are both 0mm.
This lens is designed to operate at a wavelength of 587.6nm. It does not have any coating, which means it is uncoated. However, it is important to note that uncoated lenses can suffer from reduced transmission and increased reflection, especially at larger angles of incidence.
The lens data provided here is valid and the lens is in stock, according to the vendor's website. This lens would be suitable for use in a variety of optical systems, including imaging systems, beam shaping systems, and interferometry systems.
