ASL10142-780 1 in Dia. UVFS High-Precision; CNC Polished Aspheric Lenses; NA=0.143; EFL=79mm 780nm V Coat

The ASL10142-780 is a high-precision aspheric lens, meticulously crafted by Thorlabs. This lens is designed for use with a wavelength of 780nm, making it suitable for various applications in the near-infrared spectrum. The lens is fabricated from UVFS material, a unique type of glass specifically engineered for optical applications.

The lens boasts an effective focal length (EFL) of 79mm, which is a crucial parameter in lens selection. The EFL determines the distance from the lens to the focal point, influencing the overall design and functionality of the optical system.

The ASL10142-780 features a high numerical aperture (NA) of 0.143. The NA is a measure of the lens' light-gathering capability and the depth of the focus it can achieve. A higher NA allows for greater resolution and a shallower depth of field, making this lens ideal for high-resolution imaging applications.

The lens is CNC polished, ensuring superior surface quality and accuracy. This level of precision is essential for applications that require high-quality imaging or precise light control.

The lens is coated with a broadband anti-reflection coating, specifically designed for 780nm. This coating reduces surface reflections, enhancing the lens' transmission and improving overall system performance.
