The AC300-100-A is a high-quality, unmounted achromatic doublet lens from Thorlabs, designed for use in the 400-700nm spectral range. This lens, with a catalog number AC300-100-A, is currently in stock and available for immediate purchase from Thorlabs' official website.
The lens features a base shape of a circle, with a diameter of 30mm. The edge thickness is 5mm, while the inner and outer radii are 0mm. The first and second radii of curvature are 70mm and -57mm respectively, and the third radius of curvature is -284.4mm. The center thicknesses are 5mm for the first center and 2mm for the second.
The lens is composed of two types of materials: N-BAF10 and N-SF6HT, both from Schott. The lens is coated with THo AC400-700-A on both the front and back surfaces, ensuring optimal performance in the specified spectral range.
The lens is a multiplet, meaning it is composed of multiple elements. This design helps to correct chromatic aberrations, making the lens suitable for a wide range of applications where high image quality is required.
