13-172 25 mm Dia. Hoya ND-0.3 Absorptive Neutral Density Filter; OD 1 600-1050nm
The 13-172 is a Neutral Density Filter by Hoya, available from Edmund Optics. This absorptive filter boasts a 25 mm diameter and a thickness of 1 mm, making it a compact yet robust solution for various optical applications. The ND-0.3 designation indicates a 0.3 neutral density, which translates to a 1-stop reduction in light transmission.
The filter features a thin lens shape, optimized for minimal distortion and improved light transmission. The front and back surfaces are coated with EDM 13-155, a proprietary coating by Edmund Optics that enhances the filter's performance and durability.
This filter is particularly suitable for use in the near-infrared spectrum, with a wavelength of 588 nm, and is compatible with the 600-1050nm range. The catalog number 13-172 uniquely identifies this product, and it can be found on the Edmund Optics website, where it is currently in stock.
