Abstract
An optical system, in particular for endoscopic applications, is disclosed which uses wavelength-compensating optical components, in particular prisms, made of materials with different inter-element coatings and refractive indices to image significantly different wavelength-ranges (VIS and NIR) onto the same image plane of an image acquisition device, such as a CCD sensor.
