62-664 50 mm Dia. UV-VIS Metallic Based Neutral Density Filter; OD 0.6 250-700nm
This is a 50 mm diameter Neutral Density Filter, model number 62-664, sourced from the renowned optical components vendor, Edmund Optics. The filter is designed for use in the ultraviolet and visible light spectrum, with a wavelength of 588 nm.
The filter is of the Circular type, a common shape in optical components due to its ease of use and alignment. It has a thickness of 5 mm, providing sufficient structural integrity for most applications.
The filter features a UV-VIS Metallic Based coating on both the front and back surfaces, identified by the Material ID 'uvfs mal- 1965'. This coating is designed to provide neutral density, meaning it reduces the intensity of light equally across the entire spectrum, without altering the color balance. The Optical Density (OD) of this filter is 0.6, which corresponds to a reduction in light intensity of approximately 2.5 times.
The filter's geometry is that of a Thin Lens, which can be beneficial in certain optical systems due to its reduced thickness and associated weight savings.
