ASL10142M-780 1 in Dia. UVFS High-Precision; CNC Polished Aspheric Lenses; NA=0.143; EFL=79mm 780nm V Coat
The ASL10142M-780 is a high-precision aspheric lens, meticulously crafted by Thorlabs. This lens is designed for use with a wavelength of 780nm and boasts an effective focal length (EFL) of 79mm, making it suitable for a wide range of optical applications.
The lens is constructed from UVFS material, specifically UVFS mal- 1965, and features a base shape of a circle. It has a diameter of 1 inch (25.4mm) and a thickness at the edge of 3mm. The center thickness is 6mm, providing robustness and stability to the lens.
The ASL10142M-780 features an aspheric shape, which is particularly advantageous in imaging applications as it reduces spherical aberration, a common issue in spherical lenses. The lens's aspheric surface is defined by its radius of curvature (R1) of 35.8256mm and its conic constant (K1) of -0.6291.
The lens also comes with a coating, both on the front and back surfaces. This coating, referred to as tho asl10142-780, is designed to enhance the lens's performance in its intended wavelength range.
