ASL10142-1064 1 in Dia. UVFS High-Precision; CNC Polished Aspheric Lenses; NA=0.142; EFL=80mm 1064nm V Coat

The ASL10142-1064 is a high-precision aspheric lens, meticulously crafted by Thorlabs. This lens is designed for use with a wavelength of 780nm and features a circular base shape with a diameter of 1 inch (25.4mm). The lens boasts an effective focal length (EFL) of 80mm and a numerical aperture (NA) of 0.142, making it suitable for a variety of optical applications.

The lens is made from UVFS material, specifically UVFS Mal-1965, and is polished using Computer Numerical Control (CNC) techniques. This ensures a high level of precision and consistency in the lens's geometry. The inner radius of the lens is 0, while the outer radius is also 0, indicating a symmetrical design. The lens has a thickness of 3.5mm at the edge and 6mm at the center.

The ASL10142-1064 features a sophisticated aspheric surface with specific curvature radii (r1=35.8256, r2=0) and aspheric coefficients (a2 front=0, a4 front=1.4398e-07, a6 front=0, a8 front=0, a10 front=0, a12 front=0, a14 front=0, a16 front=0). These features contribute to the lens's high-performance capabilities.

The lens is coated with a V Coat, specifically the Thorlabs ASL10142-1064 coating, on both the front and back surfaces. This coating enhances the lens's durability and performance, particularly in terms of transmission and reflection.
