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 Meters
-
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.

UVM-SP-JW
-
Readouts of UV intensity and cumulative luminescence count are prompted either on the front panel or via the externally connected remote signal control. The UV intensity detection segment is intended to measure a specific intensity of light signals, while the cumulative luminescence count is designed to tally a cumulative count on all UV intensities measured, in conjunction with real-time calibration.

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:
