Description

Achromatic Lenses is often designed to minimize or eliminate chromatic aberration. These are used by either cementing two elements together or mounting the two elements in a housing, creates smaller spot sizes than comparable singlet lenses. Achromatic lenses, such as doublets and triplets, not only correct for chromatic aberration but they can also reduce spherical aberration in some instances by introducing aspheric properties. For these reasons, Achromatic lenses are commonly used in life science imaging, surface inspection and spectroscopy applications.

Sherlan Optics offers a large variety of Achromatic Lenses. Combined with one of our advanced AR coatings (covering 400-700nm, 650-1050nm, 1050-2500nm), these optimized lenses are ideal for ensuring high resolution image quality and durability. 

Additionally, Achromatic Lenses designed specifically for the Ultraviolet (UV) or Infrared (IR) are available, which offer superior performance when compared to a standard Achromatic Lens that has been coated for the same or comparable wavelength range. For these reasons, Achromatic lenses are commonly used in life science imaging, surface inspection and spectroscopy application.

Sherlan Optics is able to specialize in manufacturing high precision custom Achromatic lenses according to customer’s specifications.
