Lindsey Optics Brilliant FS IR ND with Anti-Reflection Coating (6.6 x 6.6", 4-Stop)

This 4-stop, 6.6 x 6.6" Brilliant FS IR ND with Anti-Reflection Coating from Lindsey Optics is a full-spectrum neutral density filter that attenuates all wavelengths of light including UV, Visible and Infra-Red. Its 1.2 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed without overexposing your image. A durable anti-reflection coating on both sides of the glass helps reduce flare from stray light hitting the filter. The neutral density is dyed into the glass itself, and won't scratch off, and the filter has a unique serial number to help you keep track of your filters.
