34-197 40mm Dia. x 100mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm
This is a 40mm diameter, 100mm focal length double-convex lens, manufactured by Edmund Optics. The lens is made from N-BK7 Schott glass, a popular choice for its high refractive index and low dispersion. The lens features a YAG-BBAR coating on both the front and back surfaces, enhancing its performance in the 500-1100nm wavelength range.
The lens has a center thickness of 8mm and an edge thickness of 4.04mm, providing excellent structural integrity. The front and back radii of curvature are 101.98mm and -101.98mm respectively, contributing to its double-convex geometry. The back focal length is 97.33mm, and the effective focal length is 100mm.
The YAG-BBAR coating on this lens is a type of anti-reflection coating that reduces surface reflections and increases transmission. This coating is particularly effective in the 500-1100nm wavelength range, making this lens ideal for applications such as laser systems, optical imaging, and machine vision.
