  • Color Sensor & Proximity Detection

    ams AG

    The ams family of color and Ambient Light Sensing (ALS) sensors combined with proximity detection provides red, green, blue, and clear (RGBC) or green and clear (ALS) light sensing and proximity detection. These modules also contain an IR LED for the proximity function. Both the light and proximity sensing functions feature high sensitivity and a wide dynamic range, so these devices may be placed behind the dark bezels of smartphones, monitors, laptops and TVs.

  • LED

    Appointech, Inc.

    light-emitting diode (LED) is a two-lead semiconductor light source. It is a pn junction diode, which emits light when activated. When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons.

  • Fork Sensors

    SICK Sensor Intelligence

    Fork sensors, which operate using a through-beam design, combine the sender and receiver in a single housing. As a result, alignment is no longer time-consuming. Even very slight differences in light attenuation are detected due to highly focused light emission and high detection accuracy. Easy installation, high immunity to ambient light, and a wide range of fork widths are some of the many advantages that SICK fork sensors offer. Applications include detecting labels or parts on conveyors.

    OptCom Co., Ltd

    O-E probe is the unit to convert optical signals to electrical signals. It can be connected to Oscilloscopes or data loggers via a BNC connector and monitor the conversion waveform. It can acquire the optical signal easily by just pointing the optical fiber probe at the light source. Recently, more and more light sources utilize optical modulation for next generation lighting such as LED. Acquiring the emission timing is required to measure the emission phenomenon of the light source. This O-E probe unit is the ideal tool for these tasks.

  • Long Pulse Solar Simulator

    Wacom Electric Co., Ltd.

    This solar simulator system has been developed for evaluation of properties of photovoltaic modules. Consisting of a light source unit, a sample stage, and a measurement/data processing unit, this system irradiates light which is similar to sunbeams in spectral distribution and in intensity, over a 1500mm?~1200mm area for 80-800mseconds.

  • Photometers

    MRC ltd.

    Photometry / spectrophotometry is an assay based on measurement of the absorbance of a specific wavelength of light while passing through a fixed path-length through a cuvette of liquid test sample. The absorbance is compared with a blank and standards with graded amounts of the target compound. In colorimetry, The emitted light is of a specific visible wavelength.

  • Color Sensor

    ams AG

    The color sensor product family includes both RGB (Red, Green, Blue) and high-accuracy XYZ light sensors for precise color measurement, determination, and discrimination. XYZ sensors are capable of providing xy chromaticity co-ordinates in accordance with the CIE 1931 color map. The ams color sensors include filters to block unwanted IR light in the visible spectral range, enabling highly accurate color measurement. Their high sensitivity coupled with their wide dynamic range make them well suited to continuous color temperature measurement of ambient light in display management systems, and automatic-white-balance assistance in camera applications. Some products have additional IR channels to assist with IR light source identification.

  • Single Nano Particle Size Analyzer

    IG-1000 - Shimadzu Corp.

    Voyaging into the Single Nano Region The IG-1000 Plus Single Nano Particle Size Analyzer: An Instrument That Goes Beyond the Single Nano Region and Enters the Sub Nano Region This instrument uses the induced grating (IG) method, which is based on a new principle for measuring the size of nanoparticles using the phenomenon of dielectrophoresis and diffracted light. With dynamic light scattering, the conventional method, the light scattered by particles decreases sharply for particle sizes of less than 100 nm. Furthermore, in the single nano region (i.e., particle sizes of less than 10 nm), there are physical restrictions that make it difficult to detect scattered light, and the measurement of particle sizes also becomes difficult. The IG method does not use scattered light and so it is free from these physical restrictions, and does not require the input of the refractive index as a measurement condition. It therefore allows the size of nanoparticles to be measured simply and with high sensitivity,and is particularly effective in the analysis of single nanoparticles.
