48-620 12.5 mm Dia. UV-VIS Metallic Based Neutral Density Filter; OD 1 250-700nm

The 48-620 is a Neutral Density Filter with a 12.5 mm diameter, sourced from the renowned optical components vendor, Edmund Optics. This filter is designed to uniformly reduce the intensity of ultraviolet and visible light without altering its color balance, making it an ideal choice for applications that require light attenuation.

The filter boasts a Metallic Based coating on both the front and back surfaces, identified as 'edm 48-620'. This coating provides an Optical Density (OD) of 1 across the wavelength range of 250-700nm. The OD value is a logarithmic measure of the filter's ability to reduce light intensity, with an OD of 1 corresponding to a 10x reduction in light.

The 48-620 has a circular geometry with a diameter of 12.5mm and a thickness of 1.5mm, conforming to a Thin Lens shape. This compact design ensures ease of integration into various optical systems.

The filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its 'Valid - in stock' weblink status. For more detailed information, users can refer to the provided catalog number and the official product webpage.
