65-820 50 mm Dia. Hoya ND-0.3 Absorptive Neutral Density (OD 2) Color Filter
The 65-820 50 mm Dia. Hoya ND-0.3 Absorptive Neutral Density (OD 2) 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 65-820 and is available for purchase through their official website.
This filter is a Circular type, constructed with a 50 mm diameter and a thickness of 2 mm. It is made from UVFS Mal-1965 material, ensuring durability and reliability in various conditions. The filter features a Thin Lens shape, which is beneficial for applications requiring minimal optical path deviation.
The 65-820 filter is coated with EDM 48-531 on both the front and back surfaces. This coating enhances the filter's performance by reducing unwanted reflections and increasing transmission. The filter's primary function is to absorb light, specifically within the 400-700 nm wavelength range, and has a neutral density of 0.3 (OD 2). This makes it ideal for applications requiring light reduction without altering the color balance.
