49-453 3mm Dia. x 6mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm

The 49-453 is a high-quality double-convex lens, boasting a 3mm diameter and a 6mm focal length. This lens is sourced from the reputable optical vendor, Edmund Optics, and is readily available in their inventory. The lens is designed for use within the near-infrared (NIR) spectrum, specifically between 600nm and 1050nm, making it suitable for a wide range of applications within this wavelength range.

The lens is constructed from Schott's n-BK7 glass, a material well-known for its excellent optical properties, including a high Abbe number and low dispersion. This makes the lens an ideal choice for applications that require high image quality and minimal chromatic aberration.

The 49-453 lens features a standard coating on both the front and back surfaces. This coating, identified as 'edm nir-i std curve', is specifically designed for use within the NIR spectrum. It enhances the lens' performance by reducing surface reflections and improving transmission within the specified wavelength range.

The lens' geometry is another notable feature. It has an edge thickness of 1.41mm and a center thickness of 1.8mm, providing a robust and durable design. The lens' effective focal length (EFL) is 6mm, and its radii of curvature are 5.88mm for the first surface and -5.88mm for the second surface. The back focal length (BFL) is 5.37mm, and both the inner and outer radii are 0mm, indicating a purely spherical lens design.
