A system includes an optical waveguide configured to receive multispectral radiation from a scene, a first optical component and a second optical component. The first optical component is configured to cause a first portion of the multispectral radiation with wavelengths in a first range to exit the optical waveguide at a first position, and a second portion of the multispectral radiation with wavelengths in a second range to travel through the optical waveguide from the first position to a second position via total internal reflection. The second optical component is configured to cause the second portion of the multispectral radiation to exit the optical waveguide at the second position.

Videoendoscope designs are provided including an objective and image sensor, preferably in the distal region, the image sensor having a micro-lens array with micro-lens offsets designed for a designated chief ray angle. The scope further includes a lens group having negative optical power optically arranged adjacent to the image sensor. The negative optical power serves to modify the chief ray angle characteristic of the lens group to more closely match that required by the image sensor and micro-lens array. Some designs include a non-linear distortion in the second lens group to compensate for non-linearly varying offsets in the sensor micro-lenses. Various lens group designs and sensor arrangements are provided.
