13-195 50 mm Dia. Hoya ND-006 Absorptive Neutral Density Filter; OD 3.5 600-1050nm

The 13-195 50 mm Dia. Hoya ND-006 Absorptive Neutral Density Filter is a high-quality optical component designed for use in a wide range of applications. Sourced from the renowned optical vendor Edmund Optics, this filter boasts a catalog number of 13-195 and is available for purchase directly from their website.

This filter is a Neutral Density Filter, a type of optical element that reduces the intensity of incoming light, regardless of its wavelength, without altering its color composition. This makes it an ideal choice for applications where light intensity needs to be controlled, such as in photography, cinematography, and scientific research.

The filter features a circular shape with a diameter of 50 mm and a thickness of 2.5 mm, making it compatible with a wide range of optical systems. It is made from UVFS Mal-1965, a material known for its excellent optical properties.

The 13-195 filter is coated on both the front and back surfaces with EDM 13-161, a coating that enhances its performance and durability. The coating also gives the filter a Thin Lens shape, which is beneficial for applications that require a compact, lightweight optical design.

The filter is designed to operate at a wavelength of 900 nm, and it has an Optical Density (OD) of 3.5 in the 600-1050 nm range. This means it reduces the intensity of light in this range by a factor of 3500.
