ASL10142M-532 1 in Dia. UVFS High-Precision; CNC Polished Aspheric Lenses; NA=0.145; EFL=77.8mm 532nm V Coat
The ASL10142M-532 is a high-precision aspheric lens, meticulously crafted by Thorlabs. This lens, designed for use with a wavelength of 780nm, is made from UVFS material with the Mal-1965 index. The lens boasts a diameter of 1 inch and a thickness of 3mm at the edge, while the center thickness is 6mm.
The lens's geometry is intricately designed, with an inner radius of 0mm, an outer radius of 0mm, and a clear aperture of 25.4mm. The effective focal length (EFL) is 77.8mm, and the numerical aperture (NA) is 0.145. The aspheric surface is defined by a conic constant of -0.6291 and aspheric coefficients up to the 16th order.
The lens features a V-coat, specifically designed for the 532nm wavelength, on both the front and back surfaces. This coating enhances the lens's performance by reducing surface reflections and improving transmission.
The ASL10142M-532 is a testament to Thorlabs' commitment to quality and precision. It is available for purchase directly from their website, where it is currently in stock.
