Gemini-Red Series

Ground / Food / Textile Analysis, NIR Handheld Miniature Application, Micro NIR Spectrometer.

  • Single optical input design integrating the 900–1700 nm and 1600–2500 nm spectral ranges into a single system. Both spectral bands share the same optical spot, enabling complete 900–2500 nm near-infrared spectral acquisition.
  • Equipped with dual 256-pixel InGaAs detectors (dual-stage TEC cooling) for separate detection of each spectral band, avoiding the significant noise increase of InGaAs detectors at longer wavelengths while maintaining both sensitivity and wavelength accuracy.
  • Each spectral band supports independent integration time and gain settings, with dedicated CPU, USB, Ethernet, and GPIO interfaces. Hardware synchronization triggering is supported with a delay of <50 ns, providing near-zero timing offset.
  • Supports high-speed data transmission via Ethernet. Compact dimensions of 210 × 180 × 75.5 mm and a weight of <4 kg, making it well suited for broadband near-infrared applications such as environmental remote sensing, agriculture and food, and geology and mining.
