G314325000 25.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-1000mm Uncoated

The G314325000 is a 25.4 mm diameter Plano-Concave lens, sourced from Qioptiq Photonics, a renowned vendor in the field of precision optics. This lens is made from N-BK7, a popular glass type known for its excellent optical properties, including a high refractive index and low dispersion.

The lens features a concave shape with a radius of curvature of -523.3 mm, which results in a negative focal length of -1000 mm. This makes it suitable for applications that require light to be diverged or dispersed, such as in beam expanders or spectrometers.

The lens has a center thickness of 1.5 mm, providing a good balance between mechanical strength and optical performance. It is uncoated, meaning it does not have any anti-reflective or other surface treatments. This may result in higher reflective losses, but it also means that the lens can be used in a wider range of wavelengths without the risk of coating damage.
