G312331329 18 mm Dia. N-BK7 Plano-Convex Lens; EFL=30mm 1064nm
This is a Plano-Convex Lens from Qioptiq Photonics, a leading provider of precision optics. The lens, identified as G312331329, has a diameter of 18 mm and a center thickness of 4.5 mm, with an edge thickness of 1.7 mm. The lens is designed with an effective focal length (EFL) of 30 mm for a wavelength of 1064 nm.
The lens is made of N-BK7, a popular glass type known for its excellent optical properties, including high transmittance and low auto-fluorescence. This makes the lens suitable for a wide range of applications, particularly in the field of laser technology.
The lens features a spherical shape, with a radius of curvature (R1) of 15.73 mm for the convex surface. The concave surface has an inner radius of 0 mm, while the outer radius is also 0 mm. This specific lens design is often used in imaging systems due to its ability to minimize spherical aberration.
The lens is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces. This anti-reflection coating is specifically designed to reduce surface reflections and increase transmission, particularly for the YAG laser wavelength of 1064 nm.
