Abstract
An optical beam splitter is provided which removes aberrations such as coma and transverse chromatic aberration by subjecting all transmitted rays to equal and opposite amounts of induction of coma and transverse chromatic aberration, by curing residual astigmatism by providing a terminal astigmatism correcting lens in each transmitted ray path, and by avoiding ghost images by ensuring adequate separation between the main image and any ghost images. The splitter thus permits the use of high resolution, low sensitivity, linear charge coupled devices in image analysis.
