Abstract:
An optical apparatus comprising:a housing having an interior supporting therein a laser arrangement that is operative to produce laser light encompassing a specified range of wavelengths along a light path to a laser light output of said housing, said housing being configured to removably receive a selected one of a plurality of removable laser tuning cartridges containing respectively different wavelength-selective elements that are tuned to respectively different wavelengths within said specified range of wavelengths; and a respective removable laser tuning cartridge supporting a wavelength-selective element that becomes inserted into said light path of said laser light within said housing by a prescribed positioning of said respective removable laser tuning cartridge with respect to said housing, and thereby sets the wavelength of laser light emitted from said laser light output of said housing to a selected wavelength within said specified range of wavelengths.
