SLSQ-30B-80N 30.0 mm Dia. x -79.7 mm FL; Double-Concave Lens Uncoated

The SLSQ-30B-80N 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, features a spherical geometry with a diameter of 30.0 mm and a base shape of circular.

The lens boasts a center thickness of 2.0 mm and an edge thickness of 5.1 mm, providing a robust and durable structure. The effective focal length (EFL) of this lens is -79.7 mm, making it suitable for applications that require strong negative magnification. The first radius of curvature (R1) is -73.6 mm, while the second radius (R2) is 73.6 mm, indicating a symmetrical design that can help minimize optical aberrations.

The lens is made from fused silica, a material known for its excellent optical properties, including high transparency and resistance to thermal shock. This makes the SLSQ-30B-80N an ideal choice for applications that require high precision and durability.

Notably, this lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While this may limit its use in certain applications that require high light transmission or resistance to environmental factors, it can be beneficial in applications where cost or simplicity are primary concerns.

According to the vendor, this item is currently in stock, ensuring quick delivery for those who need it. The lens's specifications, including its geometry, material, and coating, are all available on the vendor's website, providing a comprehensive resource for those considering this lens for their optical systems.
