ATP8730 is an ultra-high-resolution, high-speed, short-wave infrared series micro-optic spectrometer with a maximum working range of 900-1700nm. The actual working range can be customized. It adopts a 1024-pixel InGaAs array detector, and the optical path has a resolution of 30pm. A special dual sampling processing circuit is developed to reduce the noise of the CCD sensor and thus improve the signal-to-noise ratio (SNR). ATP8730 spectrometer receives SMA905 fiber input light or free-space light. The measurement spectral data can be outputted through the USB2.0/3.0 or UART port.
