Effect Description: The Hot Mirror filter reduces the amount of infrared light entering the lens (via reflection) while having no affect on the wavelengths of light in the visible spectrum. Digital sensors are especially sensitive to IR light, which can cause aberrations and colour shifting in the image. The hot mirror filter is especially useful when using a neutral density filter because the ND filter will increase the ratio of IR light to visible light. Cavision's 30 layer coating technology ensures high IR wavelength reduction accuracy. |
