SLSQ-30B-90N 30.0 mm Dia. x -89.7 mm FL; Double-Concave Lens Uncoated

The SLSQ-30B-90N is a high-quality, double-concave lens offered by OptoSigma, a leading vendor in the optical industry. This lens, designed for use in a variety of optical systems, boasts a 30.0 mm diameter and a focal length of -89.7 mm, making it suitable for applications requiring concave-concave lenses.

The lens is fabricated from fused silica, a material known for its excellent optical properties, including high transparency and resistance to thermal shock. The base shape of the lens is circular, and it features a center thickness of 2 mm and an edge thickness of 4.7 mm. The inner and outer radii are both 0, indicating a symmetrical design.

The SLSQ-30B-90N is uncoated, meaning it does not have any additional layers to enhance its optical properties. This may be suitable for applications where anti-reflection or other coatings are not required. However, users should be aware that uncoated lenses can suffer from increased reflection, which may affect the performance of the overall system.

The lens is designed to operate at a wavelength of 546.1 nm, and it is spherical in shape. This lens is currently in stock and available for immediate purchase, as indicated by its valid web link status.
