            • Low dark current
            • High shunt resistance
            • High resolution
            • A special version for 1064 nm is also available

            Special features
            • Fast rise time in 900 nm range
            • Low gain slope above bias voltage
            • Potentially low bias operation
            • Low temperature coefficient
            • Active surface diameter of up to 5 mm
          • Position-sensitive diodes (PSD)

          • These components utilize the effect of the lateral division of the generated photocurrent. The term "position sensitive detector" (PSD) refers to a component that is based on silicon PIN diode technology and is used to measure the position of the integral focus of an incoming light signal. A light spot on the PSD, for instance, is converted into a continuous electrical signal corresponding to the focal position of this spot. The position of a direction is derived from the relationship between two output currents.

            Special features
            • One-dimensional PSD
            • Two-dimensional PSD
            • Duo-lateral PSD
            • High position resolution
            • High linearity
            • Components with up to 20 mm measuring range in two directions
          • Wavelength-sensitive diodes (WS)

          • Wavelength-sensitive photodiodes utilize the effect of the wavelength-specific absorption depth of radiation in silicon. For this purpose, two p-n junctions are aligned vertically in the silicon crystal, thus enabling separate signal detection within vertically adjacent ranges. Such a configuration is particularly useful for the wavelength detection of monochromatic input signals. The calculation then merely requires the formation of a quotient between two photocurrents. The calculation of a color temperature from a non-monochromatic input signal requires two such detectors and an additional optical filter.

            Special features
            • Two vertically aligned p-n junctions
            • Measuring range: 450-950 nm

                                                      • Mass flow sensors for gases

                                                      • The thermal measuring principle is used when dealing with very high sensitivity and the precise measurement of the smallest flow rates in both directions. A heating element and temperature-sensitive resistors at the heart of the sensor monitor the mass flow rate using the temperature profile in the medium. The high-precision and fast-response sensor technology is ideal e.g. for medical ventilators to detect smallest air flows.

                                                        • Our differential pressure sensors are suitable for measuring the volume flow rate of gases according to the differential pressure procedure. The sensors record the minimum drop in pressure on a flow element (e.g. screen, nozzle, laminar flow element) which equates to a measurement for the volume flow rate. Robust, highly accurate and extremely low differential pressure sensors reliably monitor how much of the medium flows through the line at any given time.
