SLB-25.4B-60PIR2 25.4 mm Dia. x 60.8 mm FL; Coated; Double-Convex Lens 750-1550nm
The SLB-25.4B-60PIR2 is a high-quality spherical lens offered by OptoSigma, designed for use in the 750-1550nm wavelength range. This lens, with a base shape of a circle, is a double-convex lens, meaning it has two convex surfaces.
The lens has a diameter of 25.4 mm and a thickness at the edge of 1.9 mm, while the thickness at the center is 4.5 mm. The effective focal length (EFL) of this lens is 60.8 mm, which is the distance from the lens's secondary principal plane to the focal point. The back focal length (BFL) is 59.2 mm, which is the distance from the lens's rear surface to its secondary principal plane.
The lens is made of n-bk7 schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens's front and back surfaces are coated with opt ir2, a coating that enhances its performance in the infrared spectrum.
This lens is currently in stock and can be purchased directly from the OptoSigma website. With its robust specifications and high-quality construction, the SLB-25.4B-60PIR2 is an excellent choice for a wide range of optical applications.
