62-670 50 mm Dia. UV-VIS Metallic Based Neutral Density Filter; OD 2.5 250-700nm

The 62-670 is a Neutral Density Filter with a 50 mm diameter and a thickness of 5 mm, designed for use in the UV-VIS spectrum. This filter is manufactured by Edmund Optics, a leading vendor in the optical industry, and is available for purchase through their website. The catalog number for this specific filter is 62-670.

The filter features a metallic-based neutral density coating on both the front and back surfaces, identified as EDM 48-624. This coating is designed to provide a consistent attenuation of light across the UV-VIS spectrum, specifically within the wavelength range of 250-700nm. The optical density of this filter is 2.5, which corresponds to a transmission of approximately 0.67%.

The filter is designed in a thin lens shape, making it suitable for use in a variety of optical systems where space is a constraint. The geometry of the filter, including its diameter and thickness, is designed to provide excellent optical performance while minimizing optical aberrations.
