The Heliopan 40.5mm Digital UV-IR Cut Filter has been specifically designed for use with digital cameras and blocks UV and infrared radiation in order to achieve greater color separation and more accurate color reproduction. By passing only the visible spectrum, digital capture is more accurate when photographing in artificial lighting conditions.
The front and rear surfaces of the filter both feature a single anti-reflection coating. Each coating helps to increase light transmission by reducing reflections, scattered light, and ghosting. Additionally, they offer protection to the filter substrate while helping to keep the glass clean for longer than uncoated glass.
This Heliopan filter is constructed from Schott glass for increased optical clarity and color fidelity. It features a brass filter ring for durability as well as jamming prevention.
