LA1832-A N-BK7 Plano-Convex Lens; Dia:30.0 mm; f=250.0 mm ARC 350-700nm

The LA1832-A is a high-quality plano-convex lens offered by Thorlabs, a leading global manufacturer of photonics components. This lens, designed for use in the visible spectrum, boasts a diameter of 30.0 mm and a focal length of 250.0 mm, making it suitable for a wide range of optical applications.

The lens is crafted from N-BK7, a popular glass type in the optical industry due to its excellent optical properties. This material, also known as Schott glass, ensures high transmission and low dispersion, making it ideal for applications that require high image quality and color correction.

The LA1832-A features a spherical shape, with a radius of curvature of 128.8 mm on the convex side. This shape, combined with its focal length, results in a beam flattener length of 247.4 mm, which is crucial for maintaining the quality of the beam in laser applications.

The lens is coated with a broadband anti-reflection coating, designed to operate between 350-700 nm. This coating reduces surface reflections, thereby increasing the amount of light transmitted through the lens. It also helps to minimize ghost images and other optical artifacts, enhancing the overall performance of the lens.

In terms of thickness, the lens measures 1.7 mm at the edge and 2.6 mm at the center. This asymmetry is typical of plano-convex lenses and contributes to their excellent optical performance.

According to the vendor's website, the LA1832-A is currently in stock, indicating its availability for immediate purchase and delivery. This lens, like all Thorlabs products, is backed by their commitment to quality and customer service, making it a reliable choice for your optical needs.
