Tpeak ca. 80% at ZWL=350nm
Features: Baader 2-Inch ZWL 350nm U-Filter
- Halos and ghost free
- A new generation Venus filter
- Allows Amateurs to image fine detail on Venus for the first time
- The special threading has been designed to fit the wide variety of eyepieces and accessories
- The latest coating technologies permits to transmit from 300nm to 400nm, with a peak transmission of 80%
- The ultra-thin filter cell results in the maximum possible clear aperture, in order to minimize vignetting
- Due to the high optical quality and highly efficient anti-reflection multicoatings, it can be stacked and combined
- The front 'crown' of the filter incorporates milled notches which make handling and threading the filter a more secure operation in the dark
- Completely blocks the rest of the region from 200nm to 1500nm using a 40 layer dielectric coating stack, on top of a special optically polished UG-11 substrate
- Can be used with UV sensitive CCD cameras or similar imaging equipment Visual observations are not possible, since the eye is not sensitive in this spectral region
