A rotation of the plane of polarization is not, however, measured by an adjustment of the analyser, but by annulling the rotation with a compensator.
Another feature I'd like to add in the future is a weather compensator.
As a vertical expansion compensator, it requires a support every 18m.
At one end of the instrument is placed a polarizer and the biquartz, and at the other a Galilean telescope, that must be focused on the edge of biquartz, having in front of its object-glass the compensator and an analyser that is regulated for producing the sensitive tint, when the plates of the compensator have the same thickness.
AtmDCC An atmospheric dispersion compensator and field corrector (AtmDCC) is required to correct for atmospheric refraction and field curvature.
Component parts of a simple variable mica compensator for polarizing microscopes.
He had been diving in 7m and had no buoyancy compensator.
I always thought that the rear compensator is present to take account of ABS failure.
One method consists in finding directly the elliptic constants of the vibration by means of a quarterwave plate and an analyser; but the more usual plan is to measure the relative retardation of two rectangular components of the stream by a Babinet's compensator.
The chief features of Soleil's saccharimeter are the biquartz and the compensator.
The rear brake compensator can cause trouble and, at worst, replacement may entail the removal of the gasoline tank.
You can also choose to purchase a buoyancy compensator with an integrated weight system.
