AC300-080-A 30 mm Dia. N-BAF10/N-SF6HT Unmounted Achromatic Doublet; EFL=80mm 400-700nm

The AC300-080-A is a high-quality unmounted achromatic doublet lens, sourced from the renowned optical component manufacturer, Thorlabs. This lens, with a diameter of 30 mm, is designed for use in the spectral range of 400-700nm, making it suitable for a wide range of applications in the visible spectrum.

The lens features a focal length of 80mm, indicated by the 'EFL=80mm' in its name. This focal length, combined with its diameter, allows for a wide field of view while maintaining a compact form factor. The lens is constructed from two types of Schott glass, N-BAF10 and N-SF6HT, which are carefully selected and arranged to minimize chromatic aberration, a common issue in lens systems.

The lens's geometry is characterized by its edge thickness of 7.9mm, inner radius of 0mm, and outer radius of 0mm. The curvature radii of its surfaces are r1=56mm, r2=-44.2mm, and r3=-219.8mm. The center thicknesses are 8.5mm for the first surface and 2mm for the second. This complex geometry is designed to provide superior optical performance.

The lens is coated with Thorlabs' proprietary anti-reflection coating, THo AC400-700-A, on both the front and back surfaces. This coating reduces surface reflections, thereby increasing transmission and improving image quality. The lens is unmounted, providing users with the flexibility to integrate it into their own optical systems.
