An optical system with precision positioning of optical devices is disclosed generally comprising an optical device and a carrier for the optical device, where the carrier has substantially parallel first and second pivot axes and a third pivot axis that is substantially orthogonal to the first and second pivot axes that allows the optical device to be moved in three substantially orthogonal directions. In certain embodiments, the pivot axes are formed from hinges, which may be spring loaded or biased by a tensioning element running approximately forty five degrees to all three pivot axes. In some embodiments, the carrier is supported at least partly independently from an outer housing in order to insulate it from vibrations caused by vibrating devices mounted to the housing.

Reduced vibration optical system with inexpensive precision positioning assembly

A spectrally resolved monochromatic light is provided which generally comprises an incoherent small source lamp, a concave grating for spectrally resolving the wavelengths of the light to obtain a particular wavelength, and an optical fiber for collecting and transmitting the particular wavelength. The light source can also have more than one optical fiber output, each having a different monochromatic wavelength. An order sorting device, such as a filter or dichroic mirror can be used to filter out the shorter wavelength radiation resulting from higher grating orders.

Spectrally resolved light

An improved multiple grating spectrograph is provided comprising a grating changer for mounting gratings, and rotatable about an axis substantially perpendicular to grating lines such that changing from one grating to another preserves the wavelength-selecting angle of incidence of electromagnetic radiation. The grating changer preferably includes a grating holder, and an actuator for moving the holder about the axis.
