LUK-6.3-5.9-UV 6.3 mm Dia. UVFS Image Grade Plano-Concave Lens; EFL=-12.5mm Uncoated

The LUK-6.3-5.9-UV is a Spherical Lens with a Plano-Concave base shape, sourced from the reputable vendor CVI Laser Optics. This lens boasts a diameter of 6.3 mm and a center thickness of 2 mm, making it a compact and efficient optical component.

The lens is designed with an Effective Focal Length (EFL) of -12.5 mm, which is a crucial parameter in determining the lens's magnification and field of view. The negative EFL indicates that this is a diverging lens, which spreads out light rays, making it suitable for specific applications such as beam expansion or correction of divergent light.

The lens is crafted from UVFS material, specifically identified as "UVFS Mal- 1965" in the item data. This material is well-suited for applications involving ultraviolet light, given its transparency in this spectrum.

The lens's geometry includes an inner radius of 0 mm and an outer radius of 0 mm, indicating a simple, straightforward design. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors.

The lens is designed to operate at a wavelength of 404.7 nm, which is in the blue part of the visible light spectrum. This wavelength is often used in various applications, including fluorescence microscopy and laser-induced breakdown spectroscopy.
