NE502B-A Dia. 0.5 in AR-Coated Neutral Density Filter; 350-700nm; OD 0.2 AR 350-700nm
The NE502B-A is a Neutral Density Filter from Thorlabs, designed with a circular base shape and a diameter of 12.7 mm. This filter is part of the UVFS MAL-1965 material ID family and has a thickness of 1.4 mm. It is designed to operate at a wavelength of 633 nm.
The NE502B-A filter features AR coatings on both the front and back surfaces, specifically the THo NE02B-A coating. This coating is designed to operate within the 350-700 nm wavelength range, providing excellent anti-reflective properties. The filter is designed in a Thin Lens shape, which is ideal for a wide range of optical applications.
The filter's Neutral Density properties are designed to reduce the intensity of incident light without altering its color composition. This makes it an ideal choice for applications where light intensity needs to be controlled, such as in photography, laser applications, and scientific research.
The NE502B-A filter is currently in stock and available for purchase through the Thorlabs website. For more information, please refer to the provided weblink.
