67-451 4.5mm Dia. x 4.5mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 67-451 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 4.5mm and a focal length of 4.5mm, making it a versatile choice for various optical applications. The lens is made from n-lasf44 Schott, a material known for its excellent optical properties.
The lens features a front and back coating of edm nir-ii std curve, which is specifically designed for use in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm. This coating enhances the lens' performance in the NIR range, making it suitable for applications such as night vision, thermal imaging, and spectral analysis.
The lens has a thickness of 1.8mm at the edge and 2.59mm at the center. The inner and outer radii are 0mm, and the back focal length is 3.05mm. The effective focal length (EFL) is 4.5mm, which is the same as the focal length, indicating that the lens does not have any optical power added or removed from it.
