BICC-25.4-154.9-C 25.4 mm Dia. N-BK7 Laser Grade Concave-Concave Lens; EFL=-150mm Uncoated
This product is a Spherical Lens (Concave-Concave) from CVI Laser Optics, with the catalog number BICC-25.4-154.9-C. It is a high-quality optical component designed for use in laser systems and other applications where precise optical control is required.
The lens has a diameter of 25.4 mm and a center thickness of 3.2 mm. The effective focal length (EFL) is -150 mm, indicating that it is a concave lens. The first radius of curvature (R1) is -154.9 mm, and the second radius of curvature (R2) is 154.9 mm, which are typical values for a concave-convex lens. The inner and outer radii are both 0, indicating that the lens has a uniform curvature.
The lens is made from N-BK7 glass, a common material for optical components due to its excellent optical properties and high damage threshold. The glass is sourced from Schott, a leading manufacturer of high-quality optical glass.
The lens is designed for use at a wavelength of 587.6 nm. It does not have any coating, which means that it will have a high reflectivity at this wavelength. This may be desirable in some applications, but in others, a coating may be required to reduce reflections or to modify the spectral response of the lens.
