SLSQ-40-70N 40.0 mm Dia. x -70.0 mm FL; Plano-Concave Lens Uncoated

The SLSQ-40-70N is a Plano-Concave Spherical Lens, 40.0 mm in diameter, with a focal length of -70.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of fused silica, a material known for its excellent optical properties, including high transparency and resistance to thermal shock.

The lens's geometry is characterized by its concave shape, with an edge thickness of 9.0 mm and a center thickness of 2.0 mm. The inner and outer radii are both 0.0 mm, indicating a uniform curvature. The back focal length (BFL) is -71.4 mm, slightly longer than the specified focal length, which is typical for Plano-Concave lenses.

This lens is uncoated, meaning it does not have any anti-reflective or other surface treatments. While this may result in higher reflective losses, it also means the lens can be used in a wider range of wavelengths, as coatings often have specific spectral ranges.

The SLSQ-40-70N is available from OptoSigma's website and is currently in stock. It's a versatile lens suitable for various applications, especially where a negative lens is required. Please note that the lens's performance should be evaluated in the context of the specific system and application it will be used in.
