65-822 50 mm Dia. Hoya ND-0.3 Absorptive Neutral Density (OD 3) Color Filter; t=3 mm 400-700nm
The 65-822 is a 50 mm diameter, absorptive neutral density color filter, manufactured by Hoya and distributed by Edmund Optics. This filter is designed with a thickness of 3 mm and operates within the wavelength range of 400-700nm.
The filter boasts a catalog number of 65-822 and is part of the Absorptive Neutral Density (ND) series, which is characterized by its ability to reduce the intensity of all wavelengths of visible light equally, without altering their color balance. This specific filter has an optical density (OD) of 3, which translates to a transmission of 0.1%.
The 65-822 filter is coated with EDM 48-533 on both the front and back surfaces. This coating is designed to enhance the filter's performance and durability, providing protection against environmental factors and ensuring optimal light transmission.
The filter's geometry is defined by its 50 mm diameter and 3 mm thickness, making it suitable for a wide range of optical applications. Its shape is that of a thin lens, which contributes to its minimal weight and ease of integration into optical systems.
