SLSQ-30-35N 30.0 mm Dia. x -35.0 mm FL; Plano-Concave Lens Uncoated

The SLSQ-30-35N is a Plano-Concave Lens, part of OptoSigma's extensive catalog of optical elements. This lens, with a diameter of 30.0 mm, is designed for use in a wide range of optical applications. 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 a center thickness of 2.0 mm and an edge thickness of 12.3 mm. The effective focal length (EFL) is -35.0 mm, indicating that it is a diverging lens. The radius of curvature (R1) is -16.1 mm, and the back focal length (BFL) is -36.4 mm. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties.

This lens is suitable for use at a wavelength of 546.1 nm. It is important to note that the lens is spherical in shape, which may cause spherical aberration in some applications. However, this can often be corrected with the use of additional optical elements.

The lens is currently in stock and available for purchase through the OptoSigma website. Detailed specifications, including dimensional tolerances and surface quality, can be found on the product page.
