The SLB-100-400PIR2 is a Plano-Convex Spherical Lens, sourced from OptoSigma, designed for use within the wavelength range of 750-1550nm. This lens boasts a diameter of 100.0 mm and a focal length of 400.0 mm, making it suitable for a variety of optical applications.
The lens is constructed from n-bk7 schott material, a popular choice due to its excellent optical properties and versatility. The Plano-Convex geometry, specifically, features a flat front surface and a curved back surface, contributing to its ability to focus light. The lens has a thickness of 3.0 mm at the edge and 9.1 mm at the center, while the back focal length measures 394.4 mm.
The SLB-100-400PIR2 is equipped with an Opt IR2 coating on both the front and back surfaces. This anti-reflection coating is specifically designed for the infrared spectrum, reducing surface reflections and improving transmission within the specified wavelength range.
