IDAS Planetary Filters for Imaging are specialized filters designed with tuned passbands intended to enhance features of specific planetary targets. Note that these filter bandpasses are at (or beyond) the edges of the visual spectrum. The camera and optical imaging components must be designed for proper operation at these wavelengths.
This filter is used for imaging vapor and clouds on Mars and Venus as well as for imaging biological subjects. The UV bandpass design enhances in-band contrast by aggressively eliminating out-of-band light:
- Leakage of Visible Band: <1/1,000,000
- Leakage from 680nm to 1,000nm: <1/150,000
- Leakage from 1,000 to 1,200nm: <1/3,000
