SLB-25.4B-50PIR1 25.4 mm Dia. x 50.8 mm FL; Coated; Double-Convex Lens 633-1064nm
The SLB-25.4B-50PIR1 is a high-quality lens from OptoSigma, designed with a 25.4 mm diameter and a focal length of 50.8 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, meaning it has two spherical surfaces that curve outwards. This design is often used to increase the convergence of light rays, making it ideal for applications that require a tight focus. The lens has a center thickness of 5.1 mm and an edge thickness of 1.9 mm, providing a robust structure that can withstand various conditions.
The SLB-25.4B-50PIR1 is coated with opt ir1 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, particularly within the wavelength range of 633-1064nm. This makes the lens suitable for a wide range of applications, including but not limited to, laser systems, optical imaging, and machine vision.
