Negative Achromatic Lens, Spherical Aberration Lens

Overview:

An achromatic lens or achromat is a lens that is designed to limit the effects of chromatic and spherical aberration. Achromatic lenses are corrected to bring two wavelengths (typically red and blue) into focus on the same plane.

The most common type of achromat is the achromatic doublet, which is composed of two individual lenses made from glasses with different amounts of dispersion. Typically, one element is a negative (concave) element made out of flint glass such as F2, which has relatively high dispersion, and the other is a positive (convex) element made of crown glass such as BK7, which has lower dispersion. The lens elements are mounted next to each other, often cemented together, and shaped so that the chromatic aberration of one is counterbalanced by that of the other.

 

Achromatic Lenses are ideal for a range of applications, including fluorescence microscopy, image relay, inspection, or spectroscopy.

Coating Options Of Achromatic Lens:

Star Optic offers a large variety of Achromatic Lenses. The above standard achromatic lens are coated with single layer MgF2 centered at 550nm. We have other multiple anti-reflection coating options for the Ultraviolet (UV), visible, or Infrared (IR) are available, including UV-VIS, VIS-NIR, NIR II, or SWIR. 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.

 

 

Single Layer MgF2 Coating Multi-layer Anti-Reflective Coating

 

Boradband Anti-Reflective Coating

 

Dual Wavelength Anti-Reflective Coating

 

 

 

Mounting Options For Achromatic Lens:

An Achromatic Lens, which is often designed by either cementing two elements together or mounting the two elements in a housing, creates smaller spot sizes than comparable singlet lenses. Our standard achromatic lenses are unmounted. However, we can provide fixed mount and adjustable mount for our lenses.
