Broadband AR Coated Achromatic Lenses(Doublet Lenses)

Achromatic Lenses are used to minimize or eliminate chromatic aberration. The achromatic design also helps minimize spherical aberrations. Achromatic Lenses are ideal for a range of applications, including fluorescence microscopy, image relay, inspection, or spectroscopy. Achromatic Lenses, which are often designed by either cementing two elements together or mounting the two elements in a housing, create smaller spot sizes than comparable singlet lenses.

1. What do you mean by achromatic combination?


An achromatic lens can be defined as a lens which is made by acombination of two different types of lenses carrying different focal powers in a manner such that the images formed by the light of both the combined lenses are free from chromatic aberration or achromatism.


2. What are achromatic lenses used for?


Achromatic Lenses are used to minimize or eliminate chromatic aberration. The achromatic design also helps minimize spherical aberrations. Achromatic Lenses are ideal for a range of applications, including fluorescence microscopy, image relay, inspection, or spectroscopy.

BK7 Ball lenses and Half Ball Lenses
Fused Silica Ball and Half-Ball Lenses
Ball Lenses are commonly used to improve signal quality in fiber coupling applications, or for use in endoscopy or bar code scanning applications. Ball Lenses feature short back focal lengths to minimize the distance needed from the Ball Lens to the optical fiber. Uni Optics offers a variety of Ball Lenses in a range of substrates for performance in the ultraviolet to the NIR.
Micro-components-Cone Lens
3mm Diameter, Aluminum Coated, Cone Lens
Cone lenses are cylindrical rod lenses with one end worked into a conical surface. The circumference of the rod is typically ground whereas the conical element is polished.
Micro-components-Rod Lenses
Micro Sizes Rod Lens
Rod Lenses are used for fiber coupling and laser diode beam shaping, lenses with a 0mm working distance are ideal for collimation of single and multi-mode optical fibers and laser diodes because the lens can be positioned and glued directly to the emission source. For focusing applications, or in instances where the lens can’t be in direct contact with the emission source, all lenses are available with a small working distance as well.
