45-697 6.0mm Dia. x -9 FL; Uncoated; UV Plano-Concave Lens

The 45-697 is a 6.0mm diameter Plano-Concave lens with a focal length of -9 FL, sourced from Edmund Optics. This lens is uncoated and designed for use with UV light, making it suitable for a variety of applications in the ultraviolet spectrum.

The lens features a concave shape with a thickness of 3mm at the edge and 2mm at the center. The inner and outer radii are both 0, indicating a uniform curvature throughout. The base shape is circular, contributing to its versatility in optical systems.

The material ID for this lens is fused sil mal-1965, a type of fused silica known for its high transparency and resistance to thermal shock. This makes the lens ideal for use in high-power laser applications and other environments with extreme temperature fluctuations.

The lens is designed to operate at a wavelength of 587.6nm, which falls within the visible light spectrum. However, its uncoated surface makes it particularly suitable for UV applications, where the absence of a coating can help to minimize reflection and maximize transmission.
