How Can We Help?
UV photography requires a UV-pass filter (for UV-only photography) and a visible-spectrum-pass filter (also called a UV/IR cut or blocking filter). Photographs are taken with each of these filters using a full-spectrum camera.
Available filters (empirical imaging has no affiliation with these companies):
| Baader Venus-U filter | This is the standard filter which has been used for many years. It has excellent IR blocking, and the transmission is in a suitable range. It can also be easily paired with the Baader UV/IR blocking filter for photography in the visible region. One downside is that the thread sizes are standard for astronomical instruments, but not cameras. |
| Andrea “U” | The specifications of this filter are excellent, and it uses a more standard thread size than the Baader filters. |
| Kolari Vision UV Photography Filter | The specification of this filter sounds ok (though with fairly low maximum transmission of 50% at 365nm), and decent sounding IR suppression. But they haven’t published a full transmission profile. We haven’t tested it though. The colour-correcting UV/IR cut filter from the same supplier sounds ideal for getting a more sensible colour in the visible-range than the above Baader UV/IR cut filter. |
