The Hot Mirror filter reduces the amount of infra-red
light entering the lens 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. The Hot Mirror ND filter accomplishes
both tasks in one combination filter, freeing up an extra
filer stage in your matte box.
Cavision's 30 layer coating technology ensures complete IR
wavelength reduction accuracy.
