Product Specifications: Hamamatsu C10344-03

Category	Parameter	Specification / Description
General Information	Product Code	C10344-03
	Product Type	Compact PMT Module with Internal HVPS
	Series	H10722 or H11722 Series
	Description	A highly integrated, low-profile PMT module with a built-in high-voltage power supply (HVPS), voltage divider, and amplifier. The `-03` suffix typically specifies a GaAs photocathode.
Photocathode	Type	GaAs (Gallium Arsenide) (This is the key feature of the -03 variant)
	Shape	Square
	Effective Area	12.0 x 12.0 mm
	Window Material	Borosilicate Glass
Spectral Response	Range	300 nm to 930 nm (Wide range, extending to Near-Infrared)
	Peak Wavelength	~600 nm to 800 nm (Broad peak across the red spectrum)
	Key Advantage	High quantum efficiency (typically >20%) across a very wide spectrum.
Power Supply	Input Voltage	+12 V DC (Typical)
	Integrated Circuit	Contains internal HVPS. No external HV box needed.
	Current Consumption	~100 mA (Typical, at +12 V input)
Gain	Control Method	Voltage-controlled via analog input or fixed.
	Adjustable Range	Up to 1 x 10<sup>6</sup>
Output	Signal	Analog voltage output (e.g., 0-10 V)
	Connector	Honda Connector (4-pin) or similar multi-pin connector.
Performance	Dark Current (Typical)	5 nA to 20 nA (at max gain, room temperature) (Higher than bialkali modules due to the GaAs cathode’s lower work function)
	Dark Output Voltage	< 100 mV (Typical, at max gain)
	Anode Luminous Sensitivity	> 300 μA/lm (Typ., at 2856 K)
	Rise Time	< 20 ns
Mechanical	Housing Material	Metal (for EMI shielding) & Plastic
	Dimensions (L x W x H)	Approx. 40.0 x 40.0 x 23.5 mm (Excluding connector)
	Weight	Approx. 50 g
Environmental	Operating Temperature	0 °C to +50 °C
	Storage Temperature	-20 °C to +60 °C
Applications		Spectroscopy (NIR), Flow Cytometry, Fluorometry using red dyes, Bio-luminescence detection, High-performance OEM Analytical Instruments.
