SLB-50B-170PIR1 50.0 mm Dia. x 171.1 mm FL; Coated; Double-Convex Lens 633-1064nm
The SLB-50B-170PIR1 is a high-quality lens from OptoSigma, designed with a double-convex spherical shape and a 50.0 mm diameter. This lens boasts a long focal length of 171.1 mm, making it suitable for applications that require a tight focus or a narrow field of view.
The lens is made from n-bk7 schott, a popular material in optical systems due to its low dispersion and high Abbe number. This ensures minimal chromatic aberration, a critical factor in maintaining image quality. The lens has a center thickness of 6.6 mm and an edge thickness of 3 mm, providing structural rigidity and resistance to deformation.
The SLB-50B-170PIR1 features a coating of opt ir1 on both the front and back surfaces. This coating enhances the lens's performance in the infrared spectrum, specifically between 633 and 1064 nm. It improves transmission, reduces reflection, and protects the lens from environmental hazards, making it ideal for infrared applications.
