127mm Round Hot Mirror (Anti-Infrared) Filter

Price: USD $209.00

Item Number: FTG127HM

Quantity:

Key Features:

Reduces the amount of infrared light which makes it to the sensor, thereby negating aberrations and colour shifting
30 layer coating technology ensures high IR wavelength reduction accuracy
Ideal for use outdoors when also using an ND filter

Specifications:

Filter Type: Hot Mirror (reflects away infrared light)
Infrared Light Transmission: below 5% transmission between ~ 730nm and 1300nm wavelengths
Shape: Round
Rear Thread Diameter: 127mm P = 0.75 (attaches to the lens' 105mm filter thread)
Material: Glass

Optional Accessories:

Adapter ring to step down to 117mm: AR127-117D10
Clamp-on rings to step down to (note AR127-117D10 as well as the clamp on ring, is required for this combination to work): 114mm (CR117-114), 110mm (CR117-110) and 100mm (CR117-100)

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.
