E690 range of photodetector heads are cylinder housings containing a high performance current to voltage converting amplifier. In the limit they are comparable in sensitivity with photomultipliers and have many superior features. These units can be connected directly to a digital voltmeter or to other equipment. Data sheets are available for download below.

Basic unit has 6 switched gain ranges between 10^3 and 10^8 - Enquire
E Series Photodetector Heads E690 Current to Voltage Converter
This unit has 7 switched gain ranges between 10^3 and 10^9 otherwise the same as E690 - Enquire This unit has 8 switched gain ranges between 10^3 and 10^10 otherwise the same as E690 - Enquire
E767 Current to Voltage Converter

E768 Current to Voltage Converter
This model incorporates a heater to maintain a stable working temperature - otherwise like E690 but with a digital interface to change the temperature (and control gain - optional) - Enquire  This model incorporates a heater to maintain a stable working temperature - otherwise like E767 but with a digital interface to change the temperature (and control gain - optional) - Enquire
E691 Current to Voltage Converter E692 Current to Voltage Converter
This model incorporates a heater to maintain a stable working temperature - otherwise like E768 but with a digital interface to change the temperature (and control gain - optional) - Enquire Circuit board with IDC feature connector to allow input current to be changed into a precision linear output square wave (0Hz to 100Khz). TTL level gain selection (10^3 to 10^7) via IDC connector. Enclosure optional and to your specification. - Enquire
E693 Current to Voltage Converter E800 Precision Current to Frequency Converter
This product is a device that allows a PC to control the gain selection and adjust the operating temperature of the E-Series Photodetector Heads. - Enquire Cables for input, output or digital interface and replacement power supplies etc - Enquire
Temperature and Gain Controller Accessories
This unit has 7 switched gain ranges between 10^3 and 10^9. Also it has back-off controls and an input selector that allows a second stage gain of 10x or 100x. - optional panel meter - see SP042 We can modify existing products to create a new design or we can design a brand new product for you       Enquire
