Light Source
-
A light source essentially is an optical transmitter that is paired with an optical receiver, both of which are connected to electrically based devices or systems. So, the source converts electrons to photons and the detector converts photons to electrons.

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.

Long Light Source
LM-A
-
The long light source is compatible with the LM-101 or the LMC-20. The light is supplied with a 50 watt tungsten halogen convection cooled light source which provides suffcient energy for use with narrow band pass filters or monochronomators in the wave length range of .35 to 2.5 microns. The light beam is chopped at 200 hz by a quiet, vibration free, synchronous motor. The housing also contains a secondary LED light source and detector for synchronization of the amplifier, plus an electro-mechanical shutter to block the light output when the instrument is zeroed. An internal collimating lens produces a narrow beam (<1") so the LM-A can be used in bell-jar and large coating systems.

Mode-Conditioned Light Sources
-
Thorlabs' Mode-Conditioned Light Sources are fiber-coupled LED sources that have an output with a flat-top profile in the far field. Common applications include the testing of multimode fused fiber components as well as verification of modal behavior in fiber-based setups. Standard fiber-coupled LED sources can have a range of output profiles that are usually not uniform and vary from source to source. This can be dependent on emitter orientation, alignment with fiber tip, and connector assembly. These mode-conditioned sources have been engineered to distribute light evenly into all transverse modes, resulting in an equilibrium modal distribution at the output. The front panel includes an adjustment knob to control the power and an output port that accepts 2.2 mm wide-key FC/PC connectors. A DS15 15 V power supply with a location-specific plug is included with each device.
