The HS4096 is a compact miniature fiber optic spectrometer with a configurable spectral range, offering high resolution (up to 0.07 nm), low stray light (~0.1%), and excellent thermal stability (wavelength drift <0.2 pixel/°C). It is equipped with low quantization dark noise and an increased number of spectral channels, making it ideal for laser measurement, plasma emission spectroscopy, color analysis, absorbance measurement, and Raman spectroscopy. It is a high-performance, cost-effective industrial-grade fiber optic spectrometer.
