Photometers & Colorimeters
Instrument Systems Optische Messtechnik GmbH
A photometer is used to measure the photometric quantities of illuminance (lx), luminous intensity (cd), luminous flux (lm), and luminance (cd/m²). The integral method and the fast response time of silicon photodiodes means that photometers can achieve an outstanding measuring speed. They are therefore ideal for performing fast goniophotometric measurements. We take great care in the development and production of photometer heads and use innovative amplifier technologies.

Adjustable Range Reflective Photoelectric Sensor
EQ-30
Panasonic Industrial Devices Sales Company of America
The compact EQ-30 Adjustable Range Reflective Photoelectric Sensor is only 68 x 20 x 40mm but delivers amazing performance. Normal Reflective Type Sensors operate by sensing the variation in the amount of incident beam. However, the Adjustable Range Reflective Sensing Type Sensors, incorporate a 2-segment photodiode to sense variation in the incident beam angle. Thus, the output is activated according to the distance of the object from the Sensor. This system helps the EQ-30 Series to be unaffected by object color or a background, enabling stable sensing. The robust housing offers IP67 protection allowing the EQ-30 Sensor to be used in the most demanding industrial environments.

Charge Integrator Amplifiers
AD8488
Analog Devices’ charge integrator amplifiers convert the charge acquired by X-ray or photodiode detectors to a voltage. The channels are composed of CMOS transistors, using typical high input impedance CMOS gates. The integrators generate charge dependent voltages using a range of selectable capacitance values that accommodate a broad range of input charge values. The integrators are followed by single-ended input to differential output voltage amplifiers where offset and low frequency noise voltages are subtracted from the input voltages.

Avalanche Photodiodes
These avalanche photodiodes (APDs) are silicon photodiodes with an internal gain mechanism. As with a conventional photodiode, absorption of incident photons creates electron-hole pairs. A high reverse bias voltage creates a strong internal electric field, which accelerates the electrons through the silicon crystal lattice and produces secondary electrons by impact ionization. The resulting electron avalanche can produce gain factors up to several hundred.

Transducers For Photodiodes
Photodiodes convert incoming electromagnetic radiation into electrical charge carriers. If photodiodes are short circuited an electrical current (photocurrent) proportional to the incident radiation intensity (number of photons per second) is induced. These photocurrents are generally small and cover the range from femtoampere (fA) to microampere (µA). Signal transducers transform this weak photocurrent to robust standard signals for reliable data transmission and simple data acquisition.
