Enhance Image Contrast and Reduce Visual Disturbance – The IR Pass filter is ideal for infrared imaging in daylight when used with a digital camera. For lunar and planetary imaging, it helps reduce atmospheric disturbances and improves contrast.
Premium Glass with Advanced Coating – Made from high-quality optical glass, the IR Pass 685nm filter features multi-layer coatings applied through ion-assisted deposition technology, ensuring scratch resistance and wavelength stability.
Durable Metal Frame with Precision Craftsmanship – The lightweight yet sturdy filter frame is CNC-machined, sandblasted, and anodized in black, followed by laser engraving. This results in an ultra-thin filter frame with a 26mm clear aperture.
Ideal for Twilight Astronomy – This filter darkens the twilight sky background, making it perfect for capturing lunar and planetary details during dawn or dusk.
Versatile Use in Infrared Photography – Besides astronomy, the IR-Pass filter is suitable for near-infrared photography, revealing unique contrasts in vegetation, sky, and clouds. It requires an infrared-sensitive camera (e.g., a modified DSLR or webcam).
High-Quality Filter Housing – The filter is securely placed in a durable, precision-engineered frame for long-lasting use.
Important Note – SVBONY filters are not designed for direct visual observation. They are intended for imaging purposes only.
