13-186 50 mm Dia. Hoya ND-25 Absorptive Neutral Density Filter; OD 0.6 600-1050nm

The 13-186 50 mm Dia. Hoya ND-25 Absorptive Neutral Density Filter is a high-quality optical component designed for use in a wide range of applications. Sourced from the renowned optical vendor Edmund Optics, this filter boasts a robust set of features and specifications that make it an excellent choice for users seeking a reliable and efficient optical solution.

This filter is a Neutral Density Filter, a type of optical element that reduces the intensity of incoming light without altering its color composition. The 13-186 model, in particular, features an Optical Density (OD) of 0.6, which corresponds to a 25% transmission rate. This makes it suitable for applications where a significant reduction in light intensity is required without compromising the color balance of the light.

The filter is designed with a Circular shape, a common configuration for Neutral Density Filters due to its ease of use and compatibility with various optical systems. It is made from UVFS Mal-1965, a material known for its excellent optical properties and durability. The filter has a diameter of 50 mm and a thickness of 2.5 mm, ensuring robustness and stability during operation.

The 13-186 filter is coated with EDM 13-152 on both the front and back surfaces. This coating enhances the filter's performance by reducing reflections and improving transmission. The filter's shape is classified as Thin Lens, a designation that indicates its suitability for use in systems where a thin, lightweight optical element is required.
