High quality chromatic focal shift and apochromat correction measurement Low cost Works with white light source to retrieve full chromatic focal shift Can be retrofitted
About
Chromatic aberrations occur due to the varying refractive indices of different colours when traveling through glass. The presence of chromatic aberration results in inaccurate images and is therefore undesirable in optics. Scientists at Imperial have devised a novel, low cost method for measuring chromatic aberration in complex optical systems. This new method employs nanoparticles and a proprietary algorithm to accurately measure the performance of lens systems in white light conditions. Current systems that measure chromatic aberrations are complex and therefore high cost.
