13-100 25 mm Dia. Hoya ND-25 Absorptive Neutral Density Filter; OD 0.5 425-675nm

The 13-100 is a 25 mm diameter Neutral Density Filter, manufactured by Hoya, a renowned name in the optical industry. This filter is designed with a circular base shape and a thickness of 2 mm, making it a compact and convenient option for various optical applications.

The filter is constructed with a unique absorptive neutral density (ND) coating, denoted as ND-25, which has an Optical Density (OD) of 0.5. This coating is specifically designed to operate within the wavelength range of 425-675nm, providing excellent performance in the visible light spectrum.

The coating on both the front and back surfaces of the filter is identified as EDM 13-083. This coating is not only responsible for the filter's neutral density properties but also contributes to its overall durability and scratch resistance.

The filter's shape is classified as a Thin Lens, indicating its suitability for use in systems where minimal optical path deviation is required. This feature makes it an ideal choice for precision optical applications.

The 13-100 filter is available from Edmund Optics, a leading vendor in the optical industry. According to the vendor's information, the filter is currently in stock, ensuring quick and easy availability for users.
