48-090 25 mm Dia. Hoya ND-0.3 Absorptive Neutral Density (OD 1) Color Filter

The 48-090 25 mm Dia. Hoya ND-0.3 Absorptive Neutral Density (OD 1) 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 48-090 and is available for purchase through their official website.

This filter is a color glass type, specifically designed to absorb a portion of the light that passes through it, thereby reducing the overall intensity. The absorptive nature of this filter makes it ideal for applications where light intensity needs to be controlled, such as in photography, cinematography, or scientific research.

The filter has a base shape of a circle, with a diameter of 25 mm, making it compatible with a wide range of optical systems. It is made from UVFS Mal-1965 material, which ensures durability and high optical performance. The filter's thickness is 1 mm, which is considered thin in the context of optical filters, making it suitable for applications where space is a constraint.

The filter's coating is another notable feature. Both the front and back surfaces of the filter are coated with EDM 48-529, which enhances its optical performance and durability. The coating helps to reduce reflections, increase transmission, and protect the filter from environmental factors.

The filter's wavelength is 588 nm, which falls within the visible light spectrum. This makes it suitable for applications involving visible light. The filter's geometry is that of a thin lens, which contributes to its compactness and versatility.
