Colour Correction Filters for White Light
Colour temperature explained:
The warmth or coldness of white light depends on its constituent wavelengths. This warmth or coldness is measured in Kelvin. The lower the Kelvin number, the warmer (yellower) the light and the higher the number the colder it is (bluer). Our lamps are typically rated at between 3000K & 8500K depending on the type.
To illustrate colour temperature a household incandescent lamp has a colour temperature of around 2800K while winter daylight at northerly latitudes has a colour temperature of around 8500K.
The actual colour temperature at the end of the fibre will be affected by the type fo fibre, the length and the number of bends in that fibre. The following colour correction filters can be fitted to our light sources in order to change the colour of the light entering the fibre. The exact light colour at the end of the fibre may be affected by the aforementioned variables.
