HAMAMATSU C7557 Datasheet
IMAGE SENSOR
Multichannel detector head controller
C7557
For control of multichannel detector head and data acquisition
C7557 is specifically designed for basic control in multichannel photometry. When connected to a Hamamatsu multichannel detector head and a
personal computer, C7557 allows easy control of the detector head and data acquisition by using dedicated software that comes with the unit.
C7557 supports all models of Hamamatsu multichannel detector heads designed to use a CCD image sensor or InGaAs image sensor. C7557
provides various useful functions (see page 2) that efficiently collect sample data during basic operation.
C7557 controller includes a driver/amplifier circuit for operating a multichannel detector head, a power supply circuit, a temperature stabilizer
circuit, an A/D conversion circuit that converts analog signals from the detector head into digital signals, and a data interface.
The software supplied with C7557 allows easy control of the multichannel detector head and data acquisition through the SCSI interface. This
software runs on Windows 95/98/Me, by simple operation from the menu neatly displayed on the screen. This software is available with different
kinds of DLL*
*1: DLL is one of useful functions the Windows 95/98/Me. It is a library that can freely start up from application software or execute function
procedure. Software development can be made easier with DLL. To use DLL, see the operation manual that comes with the unit.
