AC127-075-A-ML In Stock

The AC127-075-A-ML by ThorLabs is an achromatic doublet designed to control chromatic aberration and can reach a spot that is diffraction limited when using a laser or other monochromatic source. The AC127-075-A-ML is Ø1/2" in size, designed to be computer optimized, and boasts engravings on the housing that ensure for easy identification.

One of the standout features of the AC127-075-A-ML is its AR coating, optimized for the 400 - 700 nm range. This coating enhances its optical performance and ensures clear, high-quality images. The AC127-075-A-ML also boasts a focal length of 75 mm. The threaded housing of the doublet features clear engraving that indicates the deposited AR coating, specific part number, and focal length of the doublet. The lens also features an engraved arrow that clearly indicates the side with the larger radius of curvature, which in turn points to the recommended light propagation direction for effective collimation of a point source.

In addition, the infinity symbol engraved on the AC127-075-A-ML lens denotes an infinite conjugate ratio, which allows for easy collimation of a diverging light source. The AC127-075-A-ML is optimized for use in the visible spectral region of 400 nm - 700 nm, with the design wavelengths based on the yellow helium "d" (587.6 nm wavelength) lines, blue/green hydrogen "F" (486.1 nm wavelength) lines, and red hydrogen "C" (656.3 nm wavelength) lines, which is utilized to determine the Abbe Number of a material.
