MPPC® modules C14452 series Optical measurement modules for low-level light detection, analog output The C14452 series are optical measurement modules capable of detecting low-level light using its built-in MPPC for the visible to near infrared region. These modules consist of an MPPC, an amplifier, a high-voltage power supply circuit, and a temperature compensation circuit. The photosensitive area is available in two sizes of ϕ1.5 mm and ϕ3 mm, and the signal output is analog. The modules operate just by connecting them to an external power supply (±5 V).

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.
