67-218 50mm Dia. x 75mm FL UV-AR Coated; UV Plano-Convex Lens UV-AR 250-425nm

The 67-218 is a UV-AR coated Plano-Convex lens, measuring 50mm in diameter and featuring a focal length of 75mm. This lens is sourced from Edmund Optics, a reputable vendor known for its high-quality optical elements. The lens is designed for use within the UV spectrum, specifically between 250-425nm, making it an ideal choice for applications such as UV imaging, spectroscopy, and other UV-based research or industrial processes.

The lens is constructed from fused silica, a material with excellent optical properties, including high transparency across a wide range of wavelengths and a low coefficient of thermal expansion. This makes the lens highly resistant to thermal shock and suitable for use in environments with varying temperatures. The lens features a spherical shape, with a radius of curvature of 34.39mm on the front surface and a planar back surface. This configuration provides a large, flat field of view, minimizing optical aberrations and ensuring high image quality.

The lens is coated with a standard UV anti-reflection coating on both the front and back surfaces. This coating is designed to reduce surface reflections and increase transmission within the UV spectrum, further enhancing the lens's performance in its intended application. The coating also provides protection against environmental contaminants and wear, ensuring the lens maintains its optical performance over time.
