SLB-25.4-250PIR1 25.4 mm Dia. x 250.0 mm FL; Coated; Plano-Convex Lens 633-1064nm

The SLB-25.4-250PIR1 is a Plano-Convex Spherical Lens, sourced from OptoSigma, with a diameter of 25.4 mm and a focal length of 250 mm. This lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion. The lens's geometry includes a 2 mm edge thickness and a 2.6 mm center thickness, contributing to its robustness and durability.

The lens's front and back surfaces are coated with opt ir1, a coating specifically designed for infrared wavelengths ranging from 633 to 1064 nm. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, making it ideal for applications in the infrared spectrum.

The lens's base shape is circular, and its geometry is spherical, which is a common choice for its ease of manufacturing and versatility in various applications. The lens's effective focal length (EFL) is 250 mm, and its back focal length (BFL) is 248.3 mm. The lens's inner and outer radii are 0, indicating a plano surface on the lens's back side.
