SLB-30B-120PIR1 30.0 mm Dia. x 120.6 mm FL; Coated; Double-Convex Lens 633-1064nm
The SLB-30B-120PIR1 is a high-quality lens from OptoSigma, designed with a 30.0 mm diameter and a focal length of 120.6 mm. This lens is made of n-bk7 schott material, a popular choice for its excellent optical properties and durability.
The lens features a double-convex geometry, with radii of curvature of 124.56 mm for the first surface and -124.56 mm for the second surface. This specific geometry allows for a wide range of applications, particularly in systems where a high level of light concentration is required.
The lens has a central thickness of 3.8 mm and an edge thickness of 2 mm, providing a robust structure that can withstand various environmental conditions. The effective focal length (EFL) is 120.6 mm, while the back focal length (BFL) is 119.4 mm.
The SLB-30B-120PIR1 is coated with 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. This makes the lens ideal for applications that require infrared transmission, such as thermal imaging and night vision systems.
