13-119 50 mm Dia. Hoya ND-25 Absorptive Neutral Density Filter; OD 0.7 425-675nm

The 13-119 is a Neutral Density Filter, specifically an absorptive type, sourced from the reputable vendor, Edmund Optics. This filter is designed with a circular shape and a 50 mm diameter, making it suitable for a wide range of optical applications. The filter boasts a thickness of 3.1 mm, ensuring durability and precision.

The 13-119 filter is coated with EDM 13-102 on both the front and back surfaces, enhancing its performance and longevity. This coating is designed to provide superior optical properties, ensuring the filter maintains its neutral density across the visible spectrum, specifically between 425-675nm.

The filter's Neutral Density (ND) value is 0.7, which is equivalent to an Optical Density (OD) of 0.7. This means it reduces the light intensity by a factor of 2.3 (approximately 57% transmission). This feature is particularly useful in applications where control over the light intensity is crucial, such as in photography, cinematography, and scientific research.

The filter is designed in a Thin Lens shape, which minimizes optical aberrations and ensures optimal performance. The catalog number for this item is 13-119, and it is currently in stock, as indicated by its weblink status. For more information, users can refer to the provided weblink.
