33-423 40mm Dia. x 80mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm
The 33-423 is a high-quality double-convex lens, boasting a 40mm diameter and an effective focal length of 80mm. This lens is sourced from Edmund Optics, a renowned vendor known for their extensive catalog of optical elements. The lens is designed for use within the near-infrared spectrum, specifically between 600nm and 1050nm, making it ideal for a variety of applications within this range.
The lens is constructed from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The double-convex shape of the lens, characterized by two convex surfaces, provides a wide field of view and low distortion. The geometry of the lens includes a thickness of 3mm at the edge and 8mm at the center, contributing to its robustness and durability.
The 33-423 lens features a front and back coating of EDM NIR-I STD Curve, a specialized coating designed to enhance performance within the near-infrared spectrum. This coating aids in reducing surface reflections, thereby increasing transmission and improving overall image quality.
