G312326331 25.4 mm Dia. N-BK7 Plano-Convex Lens; EFL=300mm
This is a Plano-Convex lens, type of spherical lens, with a circular base shape and a diameter of 25.4 mm. The lens has a thickness of 3.5 mm at the edge and 4 mm at the center, and an effective focal length (EFL) of 300mm. The front and back curvature radii are 153.99 mm and 0 mm, respectively, indicating a plano surface on one side and a curved surface on the other.
The lens is made of N-BK7, a type of glass manufactured by Schott, which is known for its excellent optical properties and wide transmission range. The lens is designed for use at a wavelength of 588 nm.
Both the front and back surfaces of the lens are coated with Qio AL RALVIS AOI 45, a type of anti-reflection coating that reduces surface reflections and increases transmission. The coating angle of incidence is 45 degrees.
The lens is sourced from Qioptiq Photonics, a leading vendor in the field of precision optics. According to the vendor's website, the lens is in stock and ready for delivery.
