AC127-030-A 12.7 mm Dia. N-BK7/SF2 Unmounted Achromatic Doublet; EFL=30mm 400-700nm
The AC127-030-A is a high-quality achromatic doublet lens from Thorlabs, designed for use in the 400-700nm wavelength range. This lens is unmounted, providing users with the flexibility to integrate it into their own systems and setups.
The lens features a base shape that is circular, with a diameter of 12.7mm. The edge thickness is 3.4mm, while the inner and outer radii are 0mm. The first radius of curvature (r1) is 17.9mm, the second radius (r2) is -13.5mm, and the third radius (r3) is -44.2mm. The center thickness at the first and second locations are 3.5mm and 1.5mm, respectively.
The lens is made from two types of materials: n-BK7 from Schott and SF2 from Schott. This combination helps to achieve superior optical performance. The lens is coated with tho ac400-700-a on both the front and back surfaces, enhancing its transmission characteristics within the specified wavelength range.
The lens has an effective focal length (EFL) of 30mm, making it suitable for a wide range of applications. The item data provided does not include information about the lens's clear aperture or its transmitted wavefront quality, so users should refer to the vendor's specifications for these details.
