High Sensitivity Spectrometer

VenusPro-NIR, NIR High Sensitivity Spectrometer

NIR high-sensitivity spectrometer, with a selectable wavelength range of 300-1100nm, the best optical resolution can reach 0.35nm, Hamamatsu S11510 area array back-illuminated CCD, signal-to-noise ratio 800:1, A/D16bit

Venus Pro-NIR spectrometer is equipped with Hamamatsu S10420 2048×64 pixels back thinned CCD. The signal-to-noise ratio is increased to 800:1, the dynamic range is increased to 50000:1, and the sensitivity in the 200-500nm range is enhanced. Therefore, this series of spectrometers is very suitable for water quality detection, gas monitoring, fluorescence spectrum measurement, and other low light measurements. The spectrometer can obtain different spectral ranges and optical resolutions by configuring gratings with different number of lines and different slits, providing a wealth of choices for scientific research and industrial testing customers. The right size is also ideal for system integration.

Product advantages：

• Area array back-illuminated CCD improves signal-to-noise ratio and dynamic range
• Small size and easy system integration
• Linear gradient filters or long-pass filters eliminate second-order and higher-order diffraction.
• Replaceable slit design can take into account both sensitivity and resolution measurement needs
• USB2.0, RS232/485 and other communication methods
• USB 2.0 for data transfer and power supply
• Supports USB2.0, RS232/485 multiple communication methods.
• Provide SDK development kit to assist customers in secondary development.
• Timing measurement, real-time display of peak wavelength and full width at half maximum (FWHM).

Application areas：

• Raman spectroscopy measurements
• Fluorescence spectrum measurement
• Near infrared weak spectrum measurement
