This is a G312355331 12.7 mm diameter Plano-Convex lens, manufactured by Qioptiq Photonics. The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and versatility. The lens has a focal length (EFL) of 150mm, making it suitable for a wide range of applications that require moderate magnification.
The lens features a spherical shape, with a planar (flat) surface on one side and a convex surface on the other. The convex surface has a radius of curvature of 77.18mm. The lens has a thickness of 2.7mm at the edge and 3mm at the center. The increased thickness at the center compared to the edge is a common characteristic of Plano-Convex lenses, designed to minimize spherical aberration and improve optical performance.
The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This coating enhances the lens's durability and resistance to environmental factors, while also reducing reflective losses and improving transmission. The lens is circular in base shape, adding to its versatility in various optical systems.
The lens data indicates a wavelength of 588nm, suggesting its use in applications where this wavelength is prevalent, such as in certain types of spectroscopy or fluorescence microscopy. The lens is currently in stock and available for purchase through the Qioptiq Photonics website.
