The SLB-40-70PIR2 is a Plano-Convex Spherical Lens, sourced from OptoSigma, with a diameter of 40.0 mm and a focal length of 70.0 mm. This lens is designed for use within the wavelength range of 750-1550nm, making it suitable for a variety of applications within the infrared spectrum.
The lens is constructed from n-bk7 schott, a popular material in optical applications due to its excellent optical properties and versatility. The Plano-Convex geometry, with a center thickness of 8.0 mm and an edge thickness of 2.0 mm, ensures a long focal length and a wide field of view. The lens also features an inner radius of 0.0 mm and an outer radius of 0.0 mm, contributing to its overall shape and functionality.
The SLB-40-70PIR2 is coated with Opt IR2 on both the front and back surfaces. This coating enhances the lens's performance within the infrared spectrum, improving transmission and reducing reflection. According to the vendor, the item is currently in stock and can be purchased directly from the OptoSigma website.
