Abstract
A novel endoscope, which can be a spectrally encoded endoscope (SEE) probe having forward-view, side-view, or a combination of forward and side views is provided herein. The SEE probe includes a light guiding component, a light focusing component, and a grating component. The probe is configured to forward a light such as a spectrally dispersed light from the grating component to a sample with no intermediate reflections between light guiding component and the grating component. A triangular grating, such as a staircase grating or an overhang grating may be used as the grating component.
