A spectroscopy system that includes a light source that generates light having a plurality of wavelengths, a light transmitter that transmits the light to a target analyte, a light receiver that receives Raman-scattered light scattered from the target analyte, and a multi-wavelength spectroscopy assembly that acquires a spectrum by splitting the Raman-scattered light transmitted from the light receiver. The multi-wavelength spectroscopy assembly includes a single diffraction grating configured to diffract the Raman-scattered light and a single concave mirror configured to focus the Raman-scattered light.

Spectroscopy system

An impedance measurement device of the present disclosure includes: an electrochemical energy device; an amplifier connected to each connection terminal of the electrochemical energy device and configured to amplify a signal introduced into a wiring; and a main board configured to receive the signal from the amplifier and measure an impedance. Accordingly, the present invention has advantages in that high resistance to electromagnetic interference may be achieved by disposing a preamplifier close to a terminal of an electrochemical energy device to amplify only the signal without amplifying a noise introduced into a wiring.
