G314002000 8 mm Dia. N-BK7 Plano-Concave Lens; EFL=-8mm Uncoated

The G314002000 is a Plano-Concave Lens with a diameter of 8 mm, sourced from Qioptiq Photonics. This lens is designed for use in optical systems that require negative focal lengths. The lens's geometry includes a center thickness of 1 mm and an effective focal length (EFL) of -8 mm, making it suitable for applications that demand a strong converging or focusing effect.

The lens is made from N-BK7, a popular optical glass due to its excellent optical properties, including a high Abbe number and low dispersion. This makes it an ideal choice for applications that require high image quality and color correction. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors. However, uncoated lenses can be more susceptible to surface reflections and may require additional anti-reflective coatings depending on the application.

The lens's geometry is spherical, with a radius of curvature (R1) of -4.134 mm. This curvature contributes to the lens's negative focal length and focusing power. The lens's inner and outer radii are both 0, indicating that it is a simple plano-concave lens without any additional features or structures.

This lens is designed for use at a wavelength of 588 nm. It is important to note that the lens's performance can vary depending on the wavelength of light used, so it is essential to consider this when selecting a lens for your application.
