AC127-030-AB-ML 12.7 mm Dia. N-BK7/N-SF2 Mounted Achromatic Doublet; EFL=30mm 400-1100nm
The AC127-030-AB-ML is a mounted achromatic doublet lens, available from Thorlabs, designed for use within the 400-1100nm wavelength range. This lens boasts a 12.7mm diameter, with a center thickness of 4mm and an edge thickness of 3.3mm. The lens features a multilayer anti-reflection (AR) coating on both the front and back surfaces, identified as 'tho ab achromatic ar', which enhances its overall transmission and reduces surface reflections.
The lens is composed of two materials: N-BK7 from Schott and N-SF2 from Schott. The curvature of the lens is defined by three radii (r1, r2, r3) and two centers, resulting in a complex lens shape. The first center has a thickness of 4mm, while the second center has a thickness of 1mm. The lens's design includes an inner radius of 0mm and an outer radius of 0mm.
This lens is part of the Multiplets subtype and has a circular base shape. The geometry of the lens is defined by its diameter, thickness edge, inner radius, outer radius, r1, r2, r3, thickness center 1, and thickness center 2. The catalog number for this item is AC127-030-AB-ML, and it can be found on Thorlabs' website with a 'Valid - in stock' status.
