FaderLux Mini Viewing Glass - Red

Ø 53 mm, H 7 mm, 31 gr

The FaderLux Viewing Glass is a tool for DOPs, Gaffers, Electricians and First ADs which can be used for checking contrast settings, for lamp adjustment, F Stop / ND calculation and calculating cloud - sun intervals.
When turned to the darkest position, the FaderLux Viewing Glass provides 99% UV protection. 
The Viewing Glass´s density can be steplessly regulated by turning the knurled ring, so that you can freely choose the grade of translucence. 
Engraved onto the outside of the fixed ring is a scale marked from 1.5 to 7, which indicates by how many Stops the light transmission is reduced.

You can read the current setting by using the mark on the knurled ring.

The scale on the Viewing Glass corresponds to the ND scale as follows:
1.5 = ND 0.3 - 0.45
2 = ND 0.6
3 = ND 0.9
4 = ND 1.2
5 = ND 1.5
6 = ND 1.8
7 = ND 2.1


This makes it very easy to measure the required ND levels, i.e. for gels and filters.
