46-221 50 x 50 mm Hoya ND-13 Absorptive Neutral Density (OD 0.9) Color Filter
The 46-221 50 x 50 mm Hoya ND-13 Absorptive Neutral Density (OD 0.9) Color Filter is a high-quality optical component designed for a wide range of applications. Sourced from the renowned vendor Edmund Optics, this filter boasts a catalog number of 46-221 and is available for purchase through their official website.
This filter is a part of the Color Glass category, specifically designed as a Rectangular filter. It is made from the material UVFS Mal- 1965, which is known for its durability and optical clarity. The filter has a thickness of 2.5 mm, making it suitable for applications that require a thin, yet robust optical element.
The filter's coating is another notable feature. Both the front and back surfaces are coated with EDM 48-528, a coating that enhances the filter's performance and longevity. The filter's geometry is defined by its width and height, which are 50 mm each, making it a square filter.
The wavelength of this filter is 588 nm, which is within the visible light spectrum. This makes it suitable for applications that involve visible light. The filter's shape is that of a Thin Lens, which is a type of lens that has a very small focal length compared to its diameter.
