Ultra-low Noise Micro Spectrometer
Stalwart has launched a new generation
of high performance ultra-thin optical fiber spectrometers: SMS-20D. It adopts
ultra-low noise CCD, and has specially designed ultra-low noise correlated
double sampling circuit, 18-bit ultra-low The ADC quantizes noise, which
greatly reduces the noise of the sensor and obtains an excellent
signal-to-noise ratio (about 8 times higher than similar products). The SMS-20D
can monitor the temperature of the optical platform in real time, thus
providing a basis for the implementation of temperature compensation, which greatly
improves the measurement reliability of the SMS-20D. The measurement results do
not change with the ambient temperature, which is the best level in the
industry.
SMS-20D can receive SMA905 fiber input light or free space light, through the USB2.0 or UART port, output the measured spectral data. It only needs a 5V DC power supply or USB power supply, which is very easy to integrate.
