KBX178AR.18 50.8 mm Dia. x 500 mm FL; IR coated; Double-Convex Lens IR 1000-1550nm

This is a high-quality Double-Convex Lens, sourced from the reputable vendor MKS/Newport. It is designed for use in the infrared spectrum, specifically between 1000nm and 1550nm, making it ideal for applications such as IR imaging, spectroscopy, and other infrared-based technologies.

The lens has a diameter of 50.8mm and a focal length of 500mm, providing a high level of magnification and precision. The base shape is circular, ensuring a wide field of view and minimal distortion. The geometry of the lens is carefully crafted, with a thickness at the edge of 3mm and a center thickness of 4.251mm, optimizing its light gathering capabilities and reducing spherical aberration.

The lens is made from N-BK7 Schott, a high-grade optical glass known for its excellent transmittance and low auto-fluorescence. This makes it ideal for applications that require high clarity and precision. The lens is coated with New AR-18 fromfigure on both the front and back surfaces, enhancing its transmission capabilities and reducing reflection, thereby improving the overall quality of the image.

The lens is spherical in shape, a design that provides a wide range of benefits, including a larger depth of field, less chromatic aberration, and a more compact design. This makes it a versatile and practical choice for a wide range of applications.
