Use of Astronomy Filters in Light Microscopy and Photomicrography

Extract
In addition to other determining factors, the optical quality of images is strongly dependent on the quality of the lenses and the spectral characteristics of the incident light in light microscopy as well as in astronomy. Chromatic aberration is one of the most important reasons for limitations of the hotgraphic quality. Ideal lenses that are completely free from such aberrations do not exist. A little chromatic aberration remains in “high-end” apochromatic lenses. Moreover, several lenses for special applications, e.g. microscopic objectives for long focal distances and thick glass plates or objectives with an integrated iris diaphragm for observations in dark field, are mostly not apochromatically corrected because of their optical compromises.
