G311387322 12.7 mm Dia. N-BK7 Double-Convex Lens; EFL=150mm 450-700nm

This is a G311387322 model lens, a high-quality optical component sourced from Qioptiq Photonics. The lens is a symmetric convex-convex design, featuring a base shape of a circle, which is typical for such optical elements.

The lens has a diameter of 12.7 mm, making it suitable for a wide range of applications where compactness and precision are required. The edge thickness of the lens is 2.7 mm, while the center thickness is 3 mm, providing a robust structure that can withstand typical handling and usage.

The effective focal length (EFL) of this lens is 150 mm, which is a common choice for many optical systems due to its versatility. The lens is designed to work optimally with light in the wavelength range of 450-700 nm, which covers the visible light spectrum, making it suitable for various applications in imaging, illumination, and spectroscopy.

The lens is made of N-BK7, a high-quality glass material known for its excellent optical properties. This material is widely used in the optical industry due to its low dispersion and high transmission in the visible spectrum.

The lens features a broadband anti-reflection coating on both the front and back surfaces. This coating, identified as qio bbar arb2visnbk7, is designed to reduce surface reflections and increase transmission, thereby enhancing the overall performance of the lens.

In terms of geometry, the lens has a double-convex shape, with radii of curvature of 153.99 mm for both the front and back surfaces. The inner and outer radii are 0, indicating that the lens is a simple, symmetric design.
