HP-3010 200-1100nm Low-Noise Miniature Fiber Spectrometer Spectrometers Hhitgroup
Detector - Detector Type: Linear Array (CMOS) Detector - Effective Pixels: 2048 Detector - Pixel Size: 14μmx 200μm
The HP-3010 miniature spectrometer is a new low-noise miniature fiber spectrometer developed by Hhitgroup. The HY-3010 uses a high-sensitivity CMOS linear-array sensor covering the 200-1100nm wavelength range, with high sensitivity and extremely low noise. Applications include geographic spectral-data acquisition, water reflectance acquisition, transmission and reflection, spectral absorption, atomic emission spectroscopy, irradiance, absorbance, and color measurement. The HP-3010 fiber spectrometer uses a thoroughly optimized crossed asymmetric C-T optical path for high spectral resolution. Its distinctive stray-light suppression and low-noise circuit design provide excellent noise control, making it ideal for ultraviolet, visible, and near-infrared spectroscopy. The HP-3010 fiber spectrometer is compact, highly consistent, stable, and reliable. Wavelength range and optical resolution can be customized, and multiple trigger modes and secondary development support flexible application expansion.
