    Abstract: A Littrow-type spectrometer or monochromator (10) using a folded light path to provide a compact optical instrument is disclosed. Light enters the instrument through an inlet aperture on a planar mirror (14). The aperture is located at the focus of a parabolic collimetor-mirror (18). Collimated light reflected by the parabolic mirror is reflected back to the planar mirror, which is positioned at an angle to the collimated light. The light reflected from the planar mirror is directed at a planar grating (20) that produces diffracted light having all the wavelengths input into the system, including light of a selected wavelength, back towards the planar mirror. Light having the selected wavelength is thus caused to fall on the parabolic mirror. The parabolic mirror then focuses the selected wavelength of light ont a light exit aperture that is juxtaposed to the inlet light aperture. The planar grating can be rotatably mounted to scan the input light spectrum.

    Abstract: Provided is a multifocal spectrometric device capable of simultaneously performing a measurement of a plurality of sample with high sensitivity, with no restriction on the magnification. A multifocal spectrometric device 10 is a device in which beams of signal light emitted from a plurality of predetermined observation areas on samples S placed in a sample placement section (sample holder 13) are introduced into a spectrograph and thereby dispersed into spectra, the device including: a plurality of objective lenses (objective light-condensing sections) 111 individually located at positions which respectively and optically face the plurality of observation areas; and spectrograph input sections 151 provided in such a manner that each of the plurality of objective lenses 111 has one corresponding spectrograph input section 151, for introducing signal light passing through the corresponding objective lenses 111 into the spectrograph 17. Since each objective lens 111 only needs to observe one observation area, both the magnification and the numerical aperture NA can be simultaneously increased. Consequently, the proportion of the amount of light collected with the objective lens 111 to the entire amount of signal light emitted from the sample S within each observation area becomes high, and the measurement accuracy also becomes high.
