Introduction: SEK is a scientific-grade micro spectrometer for very weak light detection. It uses a Hamamatsu FT-CCD back-illuminated detector, a unique optical platform and optical components design, with lower stray light and higher sensitivity . SEK adopts on-chip thermoelectric cooling technology, which can reduce the temperature of the detector below 40 ℃ below the ambient temperature, effectively reduce the system's thermal noise and greatly improve the stability of the system. For weak light detection such as fluorescence and Raman detection, More advantage. Features: 1 can be exposed for a long time to improve the spectrometer's response to very weak light 2 The use of thermoelectric cooling technology, effectively reducing the dark noise spectrometer 3 unique light path platform design, making the sensitivity and resolution significantly improved 4 Broad band Efficient, the widest range of up to 190 ~ 1100 Technical Parameters: Detector name: Hamamatsu S7031 Detector type: Area Back-illuminated FFT-CCD Pixels: 1044 x 64 total pixels Quantization efficiency: 85% at 250 nm, peak 95% Detector area: vertical / horizontal: 24.576 mm / 1.392 mm Dark current noise: 10 e- / pixel / sec @ 0 ºC Refrigeration: within a thermoelectric cooling Wavelength range: Depending on the grating, from 190 to 1100 nm Optical resolution: 0.17 ~ 7.67 nm Signal to noise ratio: 1000: 1 A / D digits: 16 bits Dark noise: 6 RMS Counts @ 10 ms Dynamic range: 12000: 1 Integration time: 8 ms ~ 15 min Stray light: <0.08% @ 602 nm, 0.4% @ 435 nm Correction linearity:> 99%
