Cavision 3X3" Hot Mirror ND Coated Glass Filter

Description: When purchasing multiple items, please contact Cavision before payment for combined shipping rates. Key Features: Reduces the amount of infrared light which makes it to the sensor, thereby negating aberrations and colour shifting30 layer coating technology ensures high IR wavelength reduction accuracyAlso serves as an ND filter allowing for greater control over exposure settings: the filter reduces the amount of light entering the lens, thereby allowing for the use of a wider aperture or longer shutter speed than normalIdeal for use outdoors or other situations where both visible light levels and IR light pollution is highSpecifications: Filter Type: Neutral Density & Hot Mirror (reflects away infrared light) combination filterInfrared Light Transmission: below 5% transmission between ~ 730nm and 1300nm wavelengthsND Density: 0.6 (2 stop reduction), 0.9 (3 stop reduction), or 1.2 (4 stop reduction)Focal Length Range: up to approximately 70mm for full frame 35mm (not recommended for telephoto)Size: 3x3" (76.2 x 76.2mm)Thickness: 2mmMaterial: GlassEffect Description:The Hot Mirror filter reduces the amount of infrared 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 filter stage in your matte box. Cavision's 30 layer coating technology ensures high IR wavelength reduction accuracy.
