ECOPTIK (CHANGCHUN) LTD Neutral Density Filter

Neutral density filter is often used in imaging or laser applications to avoid strong light damage to camera sensors or other optical components. ND filters absorb or reflect untransmitted light to evenly reduce transmission in a given part of the spectrum.

BRD Optical makes fixed OD value neutral density filter by depositing Inconel film on a clear substrate. The advantage of the coated density filter is in the broader band and lower ripple than that of absorptive density filter. The coated wavelength can be extended to 200nm to 1100nm or more. The disadvantage is that there is some reflective light on the optical filter glass. The OD value can vary from 0.1 to 0.5. The OD value is controlled by coating Inconel thin film thickness. Regular thicken thickness of the NDF is 1.1mm or 0.55mm.Neutral density filters can be used for video, waterfalls, ophthalmology and landscape photography.
