88-275 25 mm Dia. UV-NIR Metallic Based Neutral Density Filter; OD 2 190-1700nm
The 88-275 is a 25 mm diameter Neutral Density Filter, specifically designed for use in the UV-NIR spectrum. This filter is manufactured by Edmund Optics, a leading provider of optical components. The filter is part of their extensive catalog, which includes a wide variety of optical elements sourced from vendors worldwide.
The filter has a base shape of a circle and is made from a metallic material, identified as UVFS MAL-1965. It has a thickness of 3 mm, providing durability and stability. The filter is coated on both sides with EDM 88-269, a coating that enhances its performance in the UV-NIR spectrum.
The 88-275 filter has an Optical Density (OD) of 2, which means it reduces the intensity of light by a factor of 100. This is particularly useful in applications where high light levels need to be reduced, such as in high-powered laser systems or in astronomical observations.
The filter is designed to work with a wavelength of 588 nm, which is in the yellow-green part of the visible light spectrum. However, its UV-NIR designation indicates that it is also effective in the ultraviolet and near-infrared regions of the spectrum. This makes it a versatile option for a wide range of optical applications.
The 88-275 filter has a thin lens shape, which helps to minimize optical aberrations and distortions. This is particularly important in high-precision applications, where even minor distortions can have a significant impact on performance.
