Información

Universal Fibre Optics can supply a variety of static filter types - colour filters, colour correction filters for white light and neutral density filters. See the information to the right for more information on each type.


All filters measure 45mm x 45mm. Depending on the lightsource model there may be room for one or more filters to be fitted - please contact us for advice.

Colour Filters

We can supply colour filters in any of the colours shown in the chart below. Clear filters are also available.

These are used in conjuction with a white light source to change the white light to a desired colour.

Fire Orange Golden Amber Apricot Canary
Green Jade Turquoise Italian Blue Brilliant Blue
Bright Blue Congo Violet Magenta Pink

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.

Full CTO (Full strength colour transmission orange) - Makes the light much warmer.

Half CTO (Half strength colour transmission orange) - Makes the light slightly warmer.

Full CTB (Full strength colour transmission blue) - Makes the light much colder.

Half CTB (Half strength colour transmission blue) - Makes the light slightly colder.

Neutral Density Filters

These grey filters reduce the ammount of light from the light source entering the fibre without changing its colour.

75% Transmission - Allows 75% of the light to pass

50% Transmission - Allows 50% of the light to pass

25% Transmission - Allows 25% of the light to pass
