Photon counting module C14463-050GD Fiber coupling type, low-light-level detection The C14463-050GD is a photon counting module that can detect low-level light. It consists of a TE-cooled single pixel photon counter (SPPC), amplifier, comparator, high-voltage power supply circuit, and temperature control circuit. This product is a fiber coupling type module. You can simply supply external power (±5 V) to use this module. Fiber coupling type Low-light-level measurement Built-in single pixel photon counter Particle diameter measurement High sensitivity in the visible to near IR region Fluorescence measurement Analytical instruments Absolute maximum ratings Parameter Supply voltage Operating temperature Storage temperature Symbol Vs Topr Tstg *1: 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 Parameter Positive power supply Supply voltage*2 Negative power supply *2: A power supply with 1 A or higher output must be used.
