This is a Plano-Convex Lens, a type of spherical lens, sourced from the renowned optical vendor, Edmund Optics. The lens has a diameter of 12.0mm and a focal length of 36.0mm, making it suitable for a wide range of optical applications.
The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This makes the lens ideal for use in systems where high image quality and low chromatic aberration are critical.
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 reduce reflection and increase transmission across the 500-1100nm wavelength range. This makes the lens particularly suitable for use in systems that operate in the visible and near-infrared regions of the spectrum.
The lens has a clear aperture, with no inner or outer radius specified, indicating that the entire surface of the lens is usable for optical transmission. The edge thickness of the lens is 2.01mm, while the center thickness is 3mm, providing a robust and durable design.
