13-151 12.5 mm Dia. Hoya ND-25 Absorptive Neutral Density Filter; OD 0.5 600-1050nm

The 13-151 is a Neutral Density Filter, specifically an Absorptive Neutral Density Filter, sourced from the renowned optical components vendor, Edmund Optics. This filter is designed with a circular shape, featuring a 12.5 mm diameter and a thickness of 2 mm, making it a compact and convenient option for various optical applications.

The filter boasts a wavelength of 588 nm, and its primary function is to reduce the intensity of incident light without altering its color composition. This is achieved through the use of advanced absorptive coatings, denoted as 'edm 13-151' on both the front and back surfaces of the filter. These coatings contribute to the filter's Optical Density (OD) of 0.5, which is the base 10 logarithm of the ratio of incident to transmitted irradiance.

The 13-151 filter is designed for use in the Near-Infrared (NIR) region, specifically within the wavelength range of 600-1050nm. This makes it an ideal choice for applications that require the reduction of light intensity in the NIR region without significant color distortion.

The filter is available for purchase through the Edmund Optics website, and as of the time of data collection, it is listed as 'in stock', indicating its immediate availability. For more detailed information, including pricing and additional specifications, please refer to the provided weblink.
