G312406331 31.5 mm Dia. N-BK7 Plano-Convex Lens; EFL=300mm
This is a Plano-Convex lens with a diameter of 31.5 mm, sourced from 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 300mm, making it suitable for applications that require long focal lengths.
The lens's geometry is characterized by its edge thickness of 2.2 mm and center thickness of 3 mm. The front surface has a radius of curvature (R1) of 155.66 mm, while the back surface is planar. The lens is unmounted, providing flexibility for users to mount it according to their specific requirements.
The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, making it suitable for applications that require high transmission and low reflection.
The lens's material, N-BK7, has a refractive index of 1.5168 at the specified wavelength of 588 nm. This, coupled with the lens's geometry and coating, makes it an ideal choice for various applications in the fields of imaging, metrology, beam shaping, and more.
