As a matter of fact, grating spectrometer has been widely used in various applications in recent years on account of its simple structure and high accuracy. On this basis, this study introduces the research history and development status of grating spectrometer in the last hundred years. To optimize the resolution of the grating spectrometer, the design of the instrument, the selection of optical elements, the stability of the light source and the performance of the detector should be considered comprehensively. The limit resolution in the visible range is affected by the number of lines of the grating and the quality of the optical element. In the UV range its resolution depends on the grating parameters and instrument design. The limiting resolution in the infrared range is limited by the wavelength range and the quality of the optical element. In addition, this research also involves the realization and progress of some related advanced technologies. Some hypotheses for improving the resolution of the grating spectrometer are also presented and proposed.

“…S1). These range from commercial grating spectrometers 21,22 and scanning micro-opto-electromechanical system spectrometers 23 to integrated approaches with digital planar holograms 24 or ringresonator enhancement 25 . An exceptionally high ratio of bandwidth per resolution has been reached with a grating multiplexing approach in a centimetre-size range 26 .…”

The miniaturisation of spectroscopic measurement devices opens novel information channels for size critical applications such as endoscopy or consumer electronics. Computational spectrometers in the micrometre size range have been demonstrated, however, these are calibration sensitive and based on complex reconstruction algorithms. Herein we present an angle-insensitive 3D-printed miniature spectrometer with a direct separated spatial-spectral response. The spectrometer was fabricated via two-photon direct laser writing combined with a super-fine inkjet process. It has a volume of less than 100 × 100 × 300 μm 3 . Its tailored and chirped high-frequency grating enables strongly dispersive behaviour. The miniature spectrometer features a wavelength range of 200 nm in the visible range from 490 nm to 690 nm. It has a spectral resolution of 9.2 ± 1.1 nm at 532 nm and 17.8 ± 1.7 nm at a wavelength of 633 nm. Printing this spectrometer directly onto camera sensors is feasible and can be replicated for use as a macro-pixel of a snapshot hyperspectral camera.
