Spectoscopic sampling accessory having dual measuring and viewing systems

An accessory for multiplexing spectroscopic measuring using a spectrometer, comprising:

• an imaging mirror objective having an input aperture, an output aperture and mapping a remote focus at a specimen plane with at least one remote focus,
• a supply of a first type of radiant energy to a first segment of the input aperture,
• a first optical system occupying a first segment of the output aperture,
• a second optical system occupying a second segment of the output aperture that is separate from the first segment, and
• a detector for the spectrometer, the detector being a part of at least one of the optical systems.
