Knight Optical’s Achromatic Doublets for Colposcopes

31 Oct 2019

Our optical components are regularly employed for use within the medical industry. Colposcopy, in particular, is one field where our premium optics are deployed to enable a precise and reliable examination. Ensuring the components within these devices are of the highest quality possible is of utmost importance, and that’s why we are recognised as a dependable supplier to the sector.

 Our Achromatic Doublet Lenses are typically used in endoscopic systems to correct chromatic aberration – resulting in a considerably improved image for accurate inspection. Chromatic aberration occurs when different wavelengths of light refract at different rates, and Achromatic Doublet Lenses correct this by helping to focus light to the same point.

 We hold a large inventory of stock Achromatic Doublet Lenses, in sizes from 4mm to 110mm in diameter.  For projects requiring a tailored approach, we also offer custom-made Achromatic Doublet Lenses to meet the precise needs of each application.

 Typical Specs:

Material:  BK7 (or equivalent), SF11

Overall Diameter Tolerance: +0/-0.10mm

Focal Length Tolerance:  ± 1.0%
