13-121 50 mm Dia. Hoya ND-0.3 Absorptive Neutral Density Filter; OD 1 425-675nm

The 13-121 50 mm Dia. Hoya ND-0.3 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 ideal choice for users seeking a reliable and efficient solution for their optical needs.

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 filter's Sub Type is Absorptive, meaning it achieves this attenuation through the absorption of light, rather than reflection or diffusion. This results in a more consistent and predictable performance, making it suitable for precise optical applications.

The filter is circular in shape, with a diameter of 50 mm and a thickness of 1 mm. This compact and streamlined design allows for easy integration into various optical systems, while also minimizing the risk of unwanted distortions or aberrations. The filter's material ID is UVFS MAL-1965, indicating its composition and manufacturing process.

The wavelength of this filter is 588 nm, which falls within the visible light spectrum. This makes it suitable for use in applications involving visible light, such as photography, cinematography, and scientific research.

The filter's coating further enhances its performance. Both the front and back surfaces of the filter are coated with EDM 13-087, a specialized coating that provides additional protection and enhances the filter's optical properties.

Finally, the filter's shape is Thin Lens, indicating its precise curvature and refractive index. This feature allows the filter to focus light accurately, making it an excellent choice for applications requiring high-precision optical elements.
