The Thorlabs AC254-050-C-ML and AC254-050 acromatic doublet lenses are high-quality optical components designed for use in the 1050-1620nm spectral range. These lenses are renowned for their exceptional optical performance, ensuring minimal distortion and aberrations, making them ideal for applications in laser systems, spectroscopy, and other optical instrumentation.
The AC254-050-C-ML lens is a coated achromatic doublet lens, which means it consists of two elements with different refractive indices that are designed to correct for chromatic aberrations. The coating on this lens is a broadband antireflection (BBAR) coating, which reduces reflection and increases transmission efficiency, ensuring maximum light throughput. The lens has a 50mm diameter and a focal length of 250mm, providing a 0.5x magnification.
The AC254-050, on the other hand, is an uncoated version of the same lens design. It also has a 50mm diameter and a focal length of 250mm, delivering the same 0.5x magnification. The lack of coating may make it less suitable for applications that require high transmission efficiency, but it may be more suitable for applications where cost is a significant factor.
Both lenses feature a tilt adjustment mechanism, which allows the lens to be angled up to 5 degrees from the optical axis. This feature is particularly useful in applications where the lens needs to be positioned at an angle to the light path, such as in some types of optical alignment or alignment of fiber optic cables.
In summary, the Thorlabs AC254-050-C-ML and AC254-050 acromatic doublet lenses are versatile optical components that offer excellent chromatic correction and magnification in the 1050-1620nm spectral range. The coated version offers high transmission efficiency, while the uncoated version offers cost savings for applications where transmission efficiency is less critical. The tilt adjustment feature adds flexibility to their use in various applications.
