Glass filters used for color temperature conversion of light sources or for adjusting color temperature during shooting.
The "Color Temperature Conversion Filter" is a filter that has a smooth upward or downward sloping transmission curve in the visible range. It is used for color temperature conversion of light sources or for adjusting color temperature during shooting. By adjusting the thickness of the polished material, filters with any desired color temperature conversion capability can be created. When the color of a light source visually compares to the color of a perfect black body heated to a certain temperature, and is the same or very similar, the temperature of the perfect black body is referred to as the color temperature. The reciprocal of the color temperature multiplied by 106 is taken as a unit, called the "mired," and is used as a unit to express color temperature conversion capability. 【Features】 ■ Filters with any desired color temperature conversion capability can be created by adjusting the polished thickness. ■ Used for color temperature conversion of light sources or for adjusting color temperature during shooting. ■ No angle dependency due to the angle of incidence. ■ No change in transmission and absorption wavelength characteristics. ■ Even relatively large glass substrates can be cut to any size through post-processing. *For more details, please refer to the PDF document or feel free to contact us.
