G312402525 31.5 mm Dia. N-BAK4 Plano-Convex Lens; EFL=50mm 725-1050nm
The G312402525 is a Plano-Convex lens with a diameter of 31.5 mm, sourced from Qioptiq Photonics. This lens is designed for use in the 725-1050nm wavelength range, making it suitable for a variety of applications in the near-infrared spectrum. The lens is made from N-BAK4, a type of optical glass known for its high refractive index and low dispersion, which helps to minimize chromatic aberration.
The lens has an effective focal length (EFL) of 50mm, which is the distance from the lens's principal point to the focal point when the lens is focused at infinity. This EFL makes the lens suitable for use in moderate telephoto applications. The lens has a thickness of 2mm at the edge and 6.7mm at the center, providing a good balance between compactness and optical performance.
The G312402525 is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission, improving the lens's overall light efficiency. The lens's spherical shape helps to minimize optical aberrations, further enhancing its performance.
