Description

The Baader U (Venus) Filter enables amateurs to successfully image in the deep UV from 300nm to 400nm.

The filter has a peak transmission of 80% and completely blocks the rest of the spectrum from 200nm to 1500nm.

Used to record cloud structures on Venus, the Solar Calcium K-Line is also within the passband of this filter.

 

The Baader U Filter is now the filter of choice for imagers exploring the UV world of Astro, landscape, floral, and even forensic imaging.

The latest filter has even higher transmission and improved out of band (IR) blocking and consists of a 20 layer dielectric coating stack on a special optically polished UG-11 substrate.

 

The human eye is nearly insensitive to UV, but can be damaged by it.

We recommend imaging using at least a 5″ to 8″ aperture scope (depending on camera sensor type) for good results.
