13-162 12.5 mm Dia. Hoya ND-006 Absorptive Neutral Density Filter; OD 4 600-1050nm

The 13-162 is a Neutral Density Filter, specifically designed for use in the near-infrared spectrum, with a wavelength of 900nm. This filter is manufactured by Hoya, a renowned name in the optical industry, and is available through Edmund Optics. The catalog number for this product is 13-162.

The filter is circular in shape, with a diameter of 12.5mm and a thickness of 2.85mm, making it suitable for a variety of optical applications. The geometry of the filter is designed in the shape of a thin lens, which aids in minimizing distortion and aberration.

The 13-162 filter features a unique absorptive coating on both the front and back surfaces, denoted as 'edm 13-162'. This coating provides an Optical Density (OD) of 4, which is equivalent to a transmission of 0.01%, within the wavelength range of 600-1050nm. This makes the filter highly effective in reducing light intensity without altering the color balance of the incident light.

The filter is sourced from the UVFS MAL-1965 material, which is known for its excellent optical properties and durability. The weblink provided leads to the product page on the Edmund Optics website, where the filter's availability and additional details can be found.
