SLB-25.4B-100PIR2 25.4 mm Dia. x 100.6 mm FL; Coated; Double-Convex Lens 750-1550nm
The SLB-25.4B-100PIR2 is a spherical lens with a base shape of a circle, designed and manufactured by OptoSigma. This lens is specifically designed for use within the wavelength range of 750-1550nm, making it suitable for a variety of applications within the infrared spectrum.
The lens has a diameter of 25.4mm and a thickness at the edge of 1.9mm, with a center thickness of 3.5mm. The effective focal length (EFL) of this lens is 100.6mm, and the back focal length (BFL) is 99.4mm. The first radius of curvature (R1) is 103.8mm, while the second radius of curvature (R2) is -103.8mm, indicating a double-convex lens design.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This makes it an ideal choice for a wide range of optical applications.
The lens features a coating on both the front and back surfaces, specifically an opt IR2 coating. This coating is designed to enhance the performance of the lens within the infrared spectrum, improving transmission and reducing reflection.
