Techspec MgF2 coated achromatic lenses

Share this on social media:

Edmund Optics (EO) has expanded its selection of Techspec MgF2 coated achromatic lenses. Consisting of two optical components cemented together to form an achromatic doublet, these high performance lenses include fast achromatic lenses and micro achromats. The versatile lenses are computer-optimised to correct for on-axis spherical and chromatic aberrations and offer a wide range of optical solutions for polychromatic illumination and imaging needs.

Techspec micro achromats are available in diameters ranging from 1mm to 5mm in focal lengths from 1.5mm to 20mm. These lenses are available with a single layer MgF2 coating or a broadband multi-layer coating for the visible spectrum. Micro achromatic lenses are ideal for space constrained imaging applications such as borescopes and medical imaging. Achromatic doublets are much better than simple lenses for multi-colour imaging as the two elements composing the doublet lens are paired together for their ability to correct the colour separation inherent in glass. This is an excellent, cost-effective measure to eliminate chromatic aberrations, making them the ideal choice for a variety of optical applications.
