That means the same-sized optical spectrometer, previously limited by its optical construction to a signal-to-noise ratio (SNR) of 300:1, can now be expected to stretch a linear detector to reach a SNR of well over 3000:1.
These new devices can be thought of as a cross between a microscope and an optical spectrometer, a tool that measures the wavelengths associated with different colors of light, Ben-Amotz says.
Raman spectroscopy uses a "pump" laser to stimulate the target and an optical spectrometer to analyze the emitted optical signal.

Tender issuethe significant improvements of mission-critical performances such as stray-light (de-clouding) co-registration dynamic range fordetection and detector noise by introducing a "smart" slit in an optical spectrometer shall be investigated and analysed.Compact instrument designs for future earth observation missions based on requirements of flex carbonsat sentinel-5 shall be elaborated modelled and analysed.A bread-board shall be designed and built for a proof-of-concept demonstration of the key functions of a smartslitusing a commercially available micro-mirror-array.With "smart slit" is meant the hardware function to actively block or transmit each image sample (pixel) entering the spectrometer slit.
Researchers at Oak Ridge (Tenn.) National Lab (ORNL) took a different approach and designed an optical spectrometer that can be specifically tuned, in the design stage, for specific, small-scale sensing applications.
