89-266 25mm Dia. x 35mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm
This is a high-quality Double-Convex Lens, sourced from the renowned optical vendor, Edmund Optics. The lens, identified as item number 89-266, boasts a diameter of 25mm and a focal length of 35mm, making it suitable for a wide range of optical applications.
The lens is crafted from the high-grade material, n-BK7 Schott, a borosilicate glass known for its excellent optical properties. This material ensures high transmittance and low dispersion, making it ideal for applications that require high-precision imaging.
The lens features a YAG-BBAR coating on both the front and back surfaces. This coating, which stands for Yttrium Aluminum Garnet - Broad Band Anti-Reflection, is designed to minimize reflection and maximize transmission across the spectral range of 500-1100nm. This makes the lens particularly suitable for applications that involve a broad range of wavelengths, such as multi-spectral imaging or laser systems.
The lens geometry is spherical, with radii of curvature of 35.09mm for the first surface and -35.09mm for the second surface. This design results in a back focal length of 32.81mm, which should be taken into account when integrating the lens into an optical system.
