SLB-40B-50PIR2 40.0 mm Dia. x 51.7 mm FL; Coated; Double-Convex Lens 750-1550nm
The SLB-40B-50PIR2 is a high-quality lens offered by OptoSigma, designed for use within the wavelength range of 750-1550nm. This lens boasts a 40.0 mm diameter and a focal length of 51.7 mm, making it suitable for a variety of optical applications.
The lens is constructed from n-bk7 schott, a popular material in the optical industry due to its excellent optical properties. The base shape of the lens is circular, and it features a double-convex geometry, with radii of curvature of 51.9 mm on the first surface and -51.9 mm on the second surface. This geometry contributes to the lens's high optical performance.
The SLB-40B-50PIR2 is coated with Opt IR2 on both the front and back surfaces, enhancing its performance in the infrared spectrum. The coating ensures high transmission and low reflection, making it ideal for use in applications where minimal light loss is crucial.
The lens has a thickness of 2 mm at the edge and 10 mm at the center, providing structural integrity while minimizing unnecessary weight. The inner and outer radii are both 0 mm, indicating a uniform curvature throughout the lens.
