89-208 3mm Dia. x 9mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm
This is a 3mm diameter, double-convex lens with a focal length of 9mm, designed for use within the wavelength range of 500-1100nm. The lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. The double-convex shape, with radii of curvature of 9.02mm for both the front and back surfaces, provides a high degree of focusing power. The center thickness of the lens is 1.6mm, while the edge thickness is 1.35mm, contributing to its robustness and durability.
The lens features a YAG-BBAR coating on both the front and back surfaces. This coating, designed for the wavelength range of 500-1100nm, enhances the lens's transmission capabilities within this spectrum, making it ideal for a wide range of applications, including laser systems and optical imaging.
The item data also provides information about the lens's effective focal length (EFL), which is 8.46mm, and the back focal length (BFL), which is 9mm. These parameters are crucial for designing optical systems that incorporate this lens.
