ABSTRACT:
Dichroic beam splitters having non-parallel entry and exit surfaces, reduced distance between such surfaces, and an aspherical exit surface can be advantageously used in dual channel optical systems, particularly when one channel is dedicated to infrared light and the other channel is dedicated to visible or near-infrared light.
