Infrared (IR) radiation is electromagnetic radiation whose wavelength is longer than that of visible light (400-700 nm), but shorter than that of terahertz radiation (3-300 µm) and microwaves (~30,000 um). Infrared radiation spans roughly three orders of magnitude (750 nm and 1000 µm).
Direct sunlight has a luminous efficacy of about 93 lumens per watt of radiant flux, which includes infrared (47% share of the spectrum), visible (46%), and ultra-violet (only 7%) light. Bright sunlight provides luminance of approximately 100,000 candela per square meter at the Earth's surface.

Analyser
An analyser, also spelt analyzer, is a device that analyses given data. It examines in detail the structure of the given data and tries to find patterns and relationships between parts of the data. An analyser can be a piece of hardware or a software program running on a computer.
An analyser can also be an instrument or device which conducts chemical analysis (or similar analysis) on samples or sample streams. Such samples consist of some type of matter such as solid, liquid, or gas. Many analysers perform such analyses automatically or mostly automatically, such as autoanalysers.
