AC127-050-AB-ML 12.7 mm Dia. N-BK7/N-SF2 Mounted Achromatic Doublet; EFL=50mm 400-1100nm
The AC127-050-AB-ML is a mounted achromatic doublet lens, sourced from the renowned optical component manufacturer, Thorlabs. This lens is designed for use within the spectral range of 400-1100nm, making it suitable for a wide range of optical applications.
The lens features a base shape of a circle, with a diameter of 12.7mm. It has a thickness of 5mm at the edge, and its geometry includes an inner radius of 0mm, an outer radius of 0mm, and three radii (r1, r2, r3) of 23.3mm, -22.6mm, and -102.4mm respectively. The lens is constructed from two types of materials, N-BK7 and N-SF2, both from Schott.
The AC127-050-AB-ML is coated with Thorlabs' Anti-Reflection (AR) coating, specifically the ACHROMATIC type, on both the front and back surfaces. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission.
The lens is a multiplet, meaning it is composed of multiple elements. This design allows for the correction of chromatic aberrations, ensuring high-quality imaging. The lens has a specified effective focal length (EFL) of 50mm, which is a common choice for many optical systems due to its versatility.
