Abstract

An apparatus, system and method are provided for composing an image at a selectable wavelength, wavelengths or bandwidth. Light passing through an entrance slit is dispersed into a spectrum and recorded. In an embodiment, spectral images corresponding to respective portions of an object are generated. Image data corresponding to a selected wavelength, wavelengths or bandwidth is extracted from the spectral images and compiled into an image of the object. In an embodiment, user optics are provided which allow a user to align the object with the entrance slit or to focus the light from the object onto the entrance slit.
