G312317322 22.4 mm Dia. N-BK7 Plano-Convex Lens; EFL=80mm 450-700nm

This is a G312317322 Plano-Convex Lens, a high-quality optical component sourced from Qioptiq Photonics. The lens has a diameter of 22.4 mm and a center thickness of 3.5 mm, making it suitable for a wide range of optical applications. The lens's edge thickness is 1.9 mm, providing robustness and durability.

The lens is made of N-BK7, a popular optical glass known for its excellent optical properties. The N-BK7 material ensures high transmittance and low dispersion, making it ideal for applications that require high image quality and color correction.

The lens has an effective focal length (EFL) of 80 mm, which is the distance from the lens's center to the focal point. This makes it a medium to long-focus lens, suitable for applications that require moderate magnification.

The lens is coated with Qio Bbar Arb2visnbk7 on both the front and back surfaces. This anti-reflection coating reduces surface reflections, improving the lens's transmittance and contrast. The coating is designed for use in the visible spectrum, specifically for wavelengths between 450 and 700 nm.

The lens's geometry is spherical, with a radius of curvature of 41.87 mm for the convex surface. This shape is common in optical systems due to its simplicity and ease of manufacturing. The lens's inner and outer radii are both zero, indicating that the lens is a simple plano-convex design.
