Abstract
An apparatus, method, and system for a spectrally encoded endoscope comprising a focusing lens encompassed by an light guiding component and spacer, wherein the focusing lens is substantially ball or semi-circular in shape, and the refractive index of the focusing lens is greater than the refractive index of the spacer.
Claims19
An apparatus for endoscopy comprising:
- a probe for illuminating a sample, comprising:
- a light guiding component for guiding an illumination light;
- a light focusing component;
