46-217 50 x 50 mm Hoya ND-70 Absorptive Neutral Density (OD 0.15) Color Filter

The 46-217 50 x 50 mm Hoya ND-70 Absorptive Neutral Density (OD 0.15) Color Filter is a high-quality optical component sourced from Edmund Optics. This filter is designed for use in a wide range of optical applications, offering superior performance and reliability.

The filter features a rectangular shape with dimensions of 50 x 50 mm, making it suitable for use in various optical systems. It has a thickness of 2.5 mm, providing excellent durability and resistance to external stressors. The filter is made from UVFS Mal-1965, a high-quality optical material known for its excellent light transmission properties.

The ND-70 designation indicates that this filter has a Neutral Density of 0.15, which corresponds to an Optical Density (OD) of 0.15. This means that the filter reduces the intensity of incident light by a factor of 1.82, providing effective control over light levels in the optical system. The neutral density characteristic ensures that the filter does not introduce any color casts or distortions, maintaining the color accuracy of the incident light.

The filter is coated with EDM 48-523 on both the front and back surfaces. This coating enhances the filter's performance by reducing surface reflections and improving light transmission. The coating also provides protection against environmental contaminants, ensuring the longevity and reliability of the filter.

The filter's geometry is that of a Thin Lens, which is beneficial in applications where minimal optical path length distortion is required. This makes the filter ideal for use in imaging systems, interferometers, and other precision optical instruments.
