Refrigerated fiber optic spectrometer

 

Product Introduction
The high-performance cooled micro fiber optic spectrometer developed by Jingyi Optoelectronics utilizes a 1044×64 pixel cooled linear CCD, which employs semiconductor cooling technology. The CCD can operate in a set constant temperature environment (down to -15°C), significantly reducing sensor noise and achieving an excellent signal-to-noise ratio (approximately twice higher than similar competitors). Furthermore, it enhances measurement reliability, ensuring that measurement results do not vary with environmental temperature. Additionally, a specially customized ultra-low noise CCD signal processing circuit with quantization noise less than 3 COUNTS has been developed, setting the industry benchmark. It can receive SMA905 fiber optic input light or free-space light and output measured spectral data through USB2.0 or UART ports. It requires only a 5V DC power supply, making it highly convenient for integration and use.
