This is a high-quality Double-Convex Lens, sourced from the reputable vendor MKS/Newport. It is specifically designed for use in the infrared spectrum, with a wavelength of 589nm, and is suitable for use in the 1000-1550nm range.
The lens has a diameter of 12.7mm and a thickness of 3mm at the edge, with a center thickness of 3.628mm. The effective focal length (EFL) is 62.9mm, making it a versatile option for a variety of applications. The lens is made from n-BK7 Schott, a high-grade optical glass known for its excellent transmission properties and low auto-fluorescence.
The lens features a double-convex geometry, with radii of curvature of 64.392mm for the first surface and -64.392mm for the second surface. The back focal length (BFL) is 61.69mm. The lens is coated with New AR-18 on both the front and back surfaces, providing superior anti-reflective properties and ensuring optimal performance in the infrared spectrum.
This lens is a Spherical type, which means it has a spherical surface. The lack of aspherical elements makes it a simple, yet effective solution for many optical applications. The lens is circular in base shape, adding to its versatility.
