This is a high-quality double-concave lens from Laser Components, designed with precision for optimal performance. The lens, identified as BICC-25.4/200.0C, features a base shape of a circle and is constructed with a spherical geometry.
The lens has a diameter of 25.4 mm and a thickness that varies from 4.2 mm at the edge to 3.4 mm at the center. It has an effective focal length (EFL) of -194 mm, making it suitable for applications that require a concave lens. The lens's first radius of curvature (R1) is -200 mm, while the second radius (R2) is 200 mm, indicating its double-concave nature.
The lens is made from n-BK7 Schott, a popular optical glass known for its excellent optical properties. It is designed to work with a wavelength of 633 nm. The lens does not come with any coating, making it suitable for applications where coating is not required or preferred.
