The SLB-100-250PIR2 is a Plano-Convex Spherical Lens, 100.0 mm in diameter and 250.0 mm in focal length, sourced from OptoSigma. This lens is designed for use within the wavelength range of 750-1550nm, making it suitable for a variety of applications in the infrared spectrum.
The lens is fabricated from n-bk7 schott, a popular material in optical systems due to its excellent optical properties and versatility. The Plano-Convex geometry, with a 3mm edge thickness and 13mm center thickness, ensures a wide field of view and minimal distortion. The lens's effective focal length (EFL) is 250mm, and the back focal length (BFL) is 241.4mm, providing a long focal length that enhances image quality and resolution.
The lens features a coating of opt ir2 on both the front and back surfaces, enhancing its performance within the specified wavelength range. This coating reduces surface reflections and improves transmission, ensuring optimal light passage through the lens.
