The AC254-050-A by ThorLabs is a premium achromatic doublet that is specifically designed to deliver top-of-the-line performance in the visible region. The AC254-050-A is engineered to optimize wavelengths that span the entire visible spectrum, including the red 656.3 nm "C", yellow 587.6 nm "d", and blue/green 486.1 nm "F" lines, to define the Abbe number (Vd) of a material.
To ensure optimal performance, it is important to position the side of the AC254-050-A lens that has the biggest radius of curvature (also known as the flattest side) away from the collimated beam. The doublet has a Ø1" size and features an antireflection coating that covers the 400 - 700 nm range. It also has a 50 mm focal length, making it an excellent choice for a range of applications. The AC254-050-A is conveniently engraved with its item number on the edge, ensuring easy identification and orientation. When the lens is situated with its flattest side downwards, the text will appear correctly oriented.
