SLSQ-30-200N 30.0 mm Dia. x -200.0 mm FL; Plano-Concave Lens Uncoated

The SLSQ-30-200N is a Plano-Concave Spherical Lens, sourced from OptoSigma, a renowned vendor in the optical industry. This lens, with a diameter of 30.0 mm, is designed for use in a wide range of optical applications, thanks to its precise geometry and high-quality material.

The lens features a concave surface with a radius of curvature of -92 mm, resulting in a back focal length of -201.4 mm. The center thickness of the lens is 2 mm, while the edge thickness is 3.2 mm, providing excellent structural integrity. The effective focal length (EFL) of this lens is -200 mm, making it suitable for applications that require negative focal lengths.

The lens is made of fused silica, a material known for its excellent optical properties, including high transparency across a wide spectrum, low autofluorescence, and high resistance to thermal shock and chemical etching. This makes the SLSQ-30-200N an ideal choice for applications that require high optical performance and durability.

Notably, this lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, this does not affect its performance in many applications, and users can always opt for custom coatings based on their specific requirements.

The SLSQ-30-200N is currently in stock and can be purchased directly from the vendor's website. With its robust design, high-quality material, and precise geometry, this lens is an excellent choice for various optical applications.
