The 88-817-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens has a base shape of a circle and a diameter of 9.0mm, making it suitable for a wide range of optical applications. The lens has a thickness of 1.1mm at the edge and 1.54mm at the center, providing a balanced structure for efficient light transmission.
The effective focal length (EFL) of this lens is 45.0mm, which is the distance from the lens's center to the focal point where light rays converge. The front radius (R1) of the lens is 23.26mm, and the back focal length (BFL) is 43.98mm. The lens does not have an inner radius or an outer radius.
The lens is made of N-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. This material is suitable for use in the visible and near-infrared regions of the spectrum.
The lens is coated with YAG-BBAR, a type of anti-reflection coating that covers both the front and back surfaces. This coating is designed to operate in the 500-1100nm wavelength range, reducing surface reflections and increasing transmission. The lens is also inked, which aids in identifying and handling the lens during assembly and use.
