Analytical Measurement Drug Discovery Life Science Medical Academic Res. Absorbance measurement modules with built-in photodiode array, optical elements, current-to-voltage converter The C13398-01/-02 are optics modules for absorbance measurement featuring high blocking performance (OD>4) and low noise. They are composed of Si photodiodes, beam splitters, filters, and a current-to-voltage conversion circuit. In combination with the dedicated evaluation circuit C13390 (sold separately), the analog output signals of each channel of the C13398 series can be converted into digital signals, and the results can be acquired into a PC. The C13398-01/-02 and C13390 can be driven by USB bus power. Features Simultaneous detection of 10 wavelengths: C13398-01 Simultaneous detection of 9 wavelengths of light and reference light: C13398-02 High blocking characteristics: OD>4 A dedicated evaluation circuit C13390 is available (sold separately) Compact: 89 (W) x 26 (H) x 39 (D) mm Can be mounted on optical rod (M4) C13398-01/-02 Blood analysis device KACCC0606EB Optics module Sample (Blood) Transmitted light Blood analysis device Light source Application example (Blood analysis device) Block diagram KACCC0852EB Shield case Optical block Circuit board Photodiode +V GND -V Incident light Beam splitter Filter … … … … Current-to-voltage conversion circuit Block diagram Specifications Parameter C13398-01 C13398-02 Detector Si photodiode Number of channels 10 ch Detection wavelength 340, 405, 450, 510, 546, 570, 600, 630, 660, 700 nm 340, 380, 405, 492, 510, 546, 578, 620, 690 nm, reference light FWHM 10 nm Blocking OD >4 Conversion impedance 10 7 V/A Cutoff frequency (-3 dB) 1.6 kHz Maximum output amplitude ±9.8 V Output noise voltage (Dark state) 1 mVp-p Current consumption (Dark state) ±18 mA Supply voltage ±10 V Customization of detection wavelengths and conversion impedance is possible.
