BICC-50.8/100.0C 50.8 mm Dia. x -97 mm FL; Uncoated; Double-Concave Lens

This is a double-concave lens, also known as a biconcave lens, sourced from the renowned optical components vendor, Laser Components. The lens has a base shape of a circle and is designed for use with a wavelength of 633 nanometers.

The lens has a diameter of 50.8 millimeters and a thickness that varies from 3 millimeters at the center to 9.6 millimeters at the edge. The lens's design includes two concave surfaces, with radii of curvature of -100 millimeters and 100 millimeters respectively. This results in an effective focal length (EFL) of -97 millimeters, making it suitable for applications that require a diverging lens.

The lens is made of N-BK7 glass from Schott, a material known for its excellent optical properties and wide transmission range. The lens is uncoated, meaning it does not have any additional layers to enhance its optical performance or protect it from environmental factors.

The item data indicates that this lens is in stock and available for immediate purchase.
