Sufficiently reduce visual effects and increase contrast: IR pass filters are a great asset for daylight IR imaging in digital cameras, reducing visual effects and increasing contrast when used for lunar and planetary imaging.
The IR pass 685nm filter is made of high-end glass multi-coated with ion-assisted deposition technology to ensure resistance and center wavelength stability.
The filter cell is made of lightweight and durable metal, CNC machined, sandblasted, black anodized and then laser engraved. The result is an ultra-thin filter cell that produces an effective aperture of 44mm.
The filter darkens the background of the sky at dusk, allowing you to capture images of the moon and planets at dawn and dusk.
In addition to astronomical applications, IR pass filters can also be used for nature photography in the near-infrared, revealing amazing differences in vegetation, sky, and clouds (requires the use of a camera sensitive to infrared radiation above 670nm, as a modified DSLR or webcam).
The filter comes in a high quality filter box. 7. Please note: SVBONY's filters are not designed for viewing.
