A measurement device relates to a Halios system for measuring an optical transmission path, in which at least one receiver and a compensation transmitter are optically separated from each other by an optical barrier in such a matter that a direct irradiation of said receiver by said compensation transmitter is not possible. Said compensation transmitter and a transmitter are of the same type and/or have at least a common electric optical working point in an optical working point. Said optical barrier has a compensation path, characterized by a compensation window, which attenuates the light of the compensation transmitter before it hits the receiver in such a manner that the compensation transmitter and said transmitter are operated at least in an optical working point by a controller in said identical electro-optical working point.

Multifunctional micro sensor system

A device for measuring a measured optical transmission path includes a first optical transmitter transmitting into the measured optical tramsmission path and a compensation transmitter transmitting into a compensation optical transmission path. The device includes an optical receiver for receiving transmissions from each of the first optical transmitter and the compensation transmitter. A controller controls the compensation transmitter and provides a controller output signal representative of a measured value of the first transmission path. A nose piece separates the optical transmitter from the optical receiver. The compensation transmitter is placed in a first cavity. The receiver is placed in a second cavity. A filter in the measured optical transmission path has a transmissivity for the wavelength of the light of the first optical transmitter of at least 50% and an absorption factor for the wavelength of the light of the compensation transmitter of at least 25%.

Multifunctional optical micro sensor system

An optical operating element comprises a light-emitting transmitter, an optical receiver, a prism, and a cover. The prism has a side surface that is an active sensor area, and the prism is arranged below the cover such that the active sensor area is oriented substantially parallel to the underside of the cover. The cover has a sensor region which is above the active sensor area and which has a transmittance of at most 99%, at most 95%, at most 90%, at most 80% or at most 50%. Light emitted by the transmitter is guided through the prism and passes through the active sensor area and the cover. The emitted light reflected at an object enters through the sensor region and the active sensor area and is guided through the prism to the receiver. A change in reflection is identified by an evaluation circuit and is interpreted as switching.
