Photon Counting Module 'HQ-105-PP'
Achieving ultra-low noise! A module capable of single-photon measurement up to 900nm.
The "HQ-105-PP" is an air-cooled photon counting module capable of infrared measurements up to 900nm. By using an air-cooled Peltier element to electronically cool the photomultiplier tube "R2949 (manufactured by Hamamatsu Photonics)," we have successfully reduced the Dark Counts from the conventional 250/sec to ≦20/sec (at a temperature of 25°C). Please install the fan for the Peltier element's cooling at least 5cm away from the wall. 【Features】 ■ Uses air-cooled Peltier elements (3cm×3cm×4 units) requiring a 24V, 4.5Amp power supply ■ Built-in high-voltage power supply for the photomultiplier tube (requires a 15V, 0.1mAmp power supply for the high-voltage power supply) ■ Output from the photomultiplier tube: BNC 50Ω negative pulse (an additional amplifier is required for 5V TTL conversion) ■ Dimensions: 184mm×64mm×H=114mm ■ Entrance window to the photocathode: φ7mm *For more details, please refer to the PDF document or feel free to contact us.
