Contrinex Schweiz AG
A reflex, or reflective, photoelectric sensor contains a transmitter and a receiver in a single housing, and emits a pulsed, focused light beam through a polarization filter toward a distant reflector. Reflected light returns to the sensor, passing through a second filter before arriving at the receiver. When a target object interrupts the light beam, the receiver detects the reduced light intensity and triggers the sensor.

SICK Sensor Intelligence
Luminescence sensors detect visible and non-visible marks that illuminate when using ultraviolet (UV) light. Fluorescent material and marks are reliably detected independently of their pattern, colors or surface conditions on any material. Luminescence sensors emit UV light with a wave length of approximately 375 nm. Fluorescent substances convert the UV light into long-wave visible light, which is then received and evaluated by the luminescence sensor.

Bunkoukeiki Co., Ltd
It is a device which measures the spectral sensitivity characteristics and quantum efficiency of various solar cells by irradiating solar cells with monochromatic light of constant energy and constant photon without wavelength dependence. We are constantly monitoring irradiation light quantity with our real real time light quantity monitor control system and are not influenced by fluctuation of light source, so it is a well-established control system with excellent measurement stability and measurement reproducibility.

Edmund Optics Inc.
Through the photovoltaic effect, detectors provide a means of transforming light energy to an electrical current. The root of the theory behind this phenomenon is a small energy gap between the valence and conduction bands of the detector. When light, with enough energy to excite an electron from the valence to the conduction band, is incident upon the detector, the resulting accumulation of charge leads to a flow of current in an external circuit. Since light is not the only source of energy that can excite an electron, detectors will have some amount of current that is not representative of incident light. For example, fluctuations in thermal energy can easily be mistaken for light intensity changes. A variety of these "non-light" contributions are present and, when summed up, make up the total noise within the detector.
