  • Light

    Thorlabs, Inc.

    Welcome to Thorlabs; below you will find links to light emitters, sources, and controllers, a subset of our entire line of photonics products. Our light sources are conveniently separated into coherent and incoherent sources. The coherent source category includes laser diodes, laser diode modules, tunable lasers, HeNe lasers, and femtosecond lasers, while the incoherent source link brings you to a selection of LEDs, white light, and broadband SLD sources. The Quantum Electronics category includes optical amplifiers, modulators, and gain elements that are frequently used in research and OEM applications. All of our light sources and optical amplifiers are supported by an extensive line of mounts, sockets, TEC controllers, and current controllers.

  • Light Meters

    Edmund Optics Inc.

    Light Meters are used to measure the light output of an illumination source for a number of optical applications. Light Meters are measurement devices that feature photodiodes to determine the level of light transmitted from a source. Light Meters possess simple, easy to read screens upon which measurements are displayed in one or more photometric units. Most Light Meters possess traceable NIST certification for proof of accuracy.

  • Light Meters

    PCE Instruments

    A light meter is a very sensitive electronic measuring device used to help monitor the illumination of any given area. Most light meter devices are small in size, simple to operate and equipped with an easy-to-read lighted screen made of special glass. Typically, a heavy-duty housing protects the light sensor inside the light meter from damage. A light meter is used for measuring brightness in lux (lx), foot candle (fc) or candela per square meter (cd/m²)measuring units. Some light meter devices are equipped with an internal memory or data logger to record and save measurements. The measurement of light intensity with a light meter is becoming increasingly important in the workplace due to safety concerns. Light measurement is also necessary to determine the best location and angle when installing and adjusting solar panels.

  • Light Meter

    MODEL 5202 - Kyoritsu Electrical Instruments Works, Ltd.

    Digital Light Meter 3 ranges changeable from low to high illuminance. (200/2000/20000lux) Data hold function. Digital light meter with separate light recieving sensor and meter.

  • Light Monitor

    LM-101 - Eddy Co.

    The LM-101 Light Monitor system provides an efficient and cost effective solution for monitoring coating thickness in real time. It consists of the LM-101 Light Monitor, LM-101A/AS light source, and Detector assembly.

  • Light Measurement

    Labsphere, Inc.

    Light is produced from many natural and artificial sources. Controlling light and having an accurate understanding of its output, directionality and the appearance of what it irradiates is key to product development, quality and the success of a light source. Here are just a few examples of why Labsphere is leading the industry in light measurement.

  • Light Simulator


    From the review of the scientific development history, reliable and stable artificial light sources have played a very important role in the past century. For example, the artificial solar simulator is an important part of simulating sunlight to ensure accurate performance of PV characterization. With the growth of light sensor applications, more and more requirement of light simulators (or artificial light sources) explored. One of the core technologies of Enlitech is the artificial light sources. We can manipulate different lamp types (short arc lamps, LEDs, filament lamps et. al.) to generate different spectrum-form in different light intensity levels, beam sizes, and wavelength ranges. We have launched different artificial light source products for different applications fields. For instance, SS-X series solar simulators and ILS-30 ambient light simulator are for the PV field, HAAS is highly accurate star light simulator for the space field, and ALS-300 is a general-purpose light source in science research field. These products can not only meet the needs of your application, but also speed up the process of your research or mass-production.

  • Light Sources


    There are many low cost artificial light sources used for illumination or for industrial applications: tungsten or halogen bulbs, fluorescent lamps, LED lamps etc. Some of these sources have regulated intensity of emitted light. However, there very few calibrated light sources of precisely known parameters. A light source can be considered as calibrated when its user can precisely regulate its photometric/radiometric parameters like luminance (or illuminance), radiance (or irradiance) at defined spectrum of interest. Such light sources are needed in many applications among them, in systems for testing night vision devices, VIS-NIR cameras and SWIR imagers. Inframet offers a series of calibrated light sources that can be divides into three groups:
