This is a 3 mm diameter Plano-Convex lens, manufactured by Qioptiq Photonics, a renowned vendor in the field of precision optics. The lens is mounted and features an effective focal length (EFL) of 3mm, designed for use within the wavelength range of 725-1050nm.
The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties. The lens's geometry includes a 0.34mm thickness at the edge, increasing to 1.5mm at the center, providing a curvature radius of 1.55mm on the convex side. The lens's inner and outer radii are 0, indicating a planar surface on the opposite side.
The lens is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces, enhancing its performance within the specified wavelength range. This lens, with its spherical shape, is a Sub Type of Spherical Lens, specifically a Plano-Convex lens, and is circular in base shape.
