SMS-20D

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.
