OceanOptics QEPro Spectrometer for Ocean Optics
OceanOptics QEPro Spectrometer for Ocean Optics
Product details
QE Pro is a highly sensitive spectrometer suitable for low light applications such as fluorescence measurement, DNA sequencing, and Raman analysis. The thin back illuminated CCD detector of QE Pro has high quantum efficiency, and its robust design gives it high signal-to-noise ratio performance and stability. The measurement of dark noise can be optimized by selecting an internal shutter.
Product Features
90% extremely high quantum efficiency and extremely low etalon effect
● Signal to noise ratio (>1000:1) and improved processing speed
TEC cooling (up to -15 ° C) allows the detector to have lower noise and is more conducive to low light detection
And the integration time can be continuously adjusted from 8ms to 15 minutes, and the spectrum will not be distorted or deformed
Provide a grating with 900 lines/mm (# H36), with a shining wavelength of 500nm, and good spectral response for 532nm and 785nm laser Raman spectroscopy
● Thermal stability
● Internal shutter (optional)
application
● Biotechnology applications ● Medical diagnosis ● Metallurgical analysis ● Protein and nucleic acid analysis ● Polymer analysis ● Chemistry
