SLB-50.8B-90PIR2 50.8 mm Dia. x 91.6 mm FL; Coated; Double-Convex Lens 750-1550nm
The SLB-50.8B-90PIR2 is a spherical lens with a base shape of a circle, offering a diameter of 50.8 mm and a focal length of 91.6 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is designed for use within the wavelength range of 546.1 nm, making it suitable for a variety of applications.
The lens is constructed from n-bk7 schott, a high-quality optical glass material known for its excellent transmittance and homogeneity properties. This material is often used in high-precision optical systems due to its low dispersion and high Abbe number.
The SLB-50.8B-90PIR2 features a double-convex geometry, with radii of curvature of 93.42 mm for both the front and back surfaces. This geometry contributes to the lens's high optical power and excellent imaging capabilities. The lens has an edge thickness of 2.8 mm and a center thickness of 9.8 mm, providing robustness and durability.
The lens is coated with Opt IR2 on both the front and back surfaces. This coating enhances the lens's performance in the infrared spectrum, specifically within the 750-1550 nm range, making it ideal for applications such as thermal imaging, night vision, and other infrared-based technologies.
