Light Measurement
Light Measurement is an extremely complex and intriguing field and something of a departune compared to other categories on the Bright Ideas website because the suppliers are more based around supplying scientific equipment than lights and their fittings. There are a number of techniques used in measurement, from the traditional photometer to the spectroradiometer and everything in between.
There are even companies that will provide specialists who will see to your every light measurement need on their behalf, this can be advantageous to many as you will not have to worry about the correct operation of complex equipment if it is only needed for short term use. In light measurement a photometer is an instrument that measures illuminance and irradiance. It detects scattered light intensity, fluorescence and absorbtion into various materials. They work in one of two ways, the simplest deisgn uses a photoresister that exhibits a small electrical charge that can be measured and recorded with an electronic circuit.
The second and slightly more complex (but more accurate) means of light measurement using a photometer is to utilise one that is based around the principle of counting individual incoming photons. The other major tool in light measurement is a spectroradiometer, this is a device that can be used to measure the amount of illuminesence visible at each wavelength and are commonly utilised by lighting manufacturers to ensure their products stand up to stringent standards and are not emitting any light of the incorrect wavelength. These are just a few of the measurement techniques that you will discover from the suppliers in this category.
