SLB-06B-20PIR1 6.0 mm Dia. x 20.2 mm FL; Coated; Double-Convex Lens 633-1064nm

The SLB-06B-20PIR1 is a spherical lens with a base shape of a circle, offering a versatile solution for various optical applications. This lens, sourced from OptoSigma, boasts a diameter of 6.0 mm and a focal length of 20.2 mm, making it a compact yet powerful component in optical systems.

The lens features a double-convex geometry, with radii of curvature of 20.76 mm for the first surface and -20.76 mm for the second surface. This design ensures a high level of light concentration, making it ideal for applications that require efficient light gathering and focusing. The lens has an edge thickness of 1.0 mm and a center thickness of 1.4 mm, providing robustness and durability.

The SLB-06B-20PIR1 is made from n-BK7 Schott, a high-quality optical glass known for its excellent optical properties and chemical resistance. This material ensures high transmittance across a wide spectrum, particularly in the 633-1064 nm range, making it suitable for near-infrared applications.

The lens is coated with Opt IR1 on both the front and back surfaces, enhancing its performance in the infrared region. This coating reduces reflection and increases transmission, thereby improving the overall efficiency of the optical system.
