Optics modules C13398 series Absorbance measurement module with built-in photodiode array, optical elements, current-tovoltage converter, etc. The C13398 series is an optics module for absorbance measurement featuring high blocking performance (OD>4) and low noise. It is composed of Si photodiodes, beam splitters, filters, and current-to-voltage conversion circuit. The C13398-01 can detect 10 wavelengths of light simultaneously. The C13398-02 can detect 9 wavelengths of light and a reference light simultaneously. 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 the PC. Simultaneous detection of 10 wavelengths Blood analysis device High blocking characteristics: OD>4 Absorbance analyzer Voltage output: Easy handling Compact: 38 (W) × 89 (D) × 26 (H) mm (2/3 the business card size) Can be mounted on optical rod (M4) Absolute maximum ratings (Ta=25 °C unless otherwise noted) Type no. *1: No dew condensation When there is a temperature difference between a product and the surrounding area in high humidity environment, dew condensation may occur on the product surface. Dew condensation on the product may cause deterioration in characteristics and reliability. Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the product within the absolute maximum ratings. Recommended operating conditions (Ta=25 °C) *2: Use a multiple output power supply (dual power supply) that can output 100 mA current. Electrical characteristics (Typ.
