12 10 07 Astro Systems Holland ADC
Atmospheric Dispersion Corrector
ASH has developed a high quality atmospheric dispersion corrector.
This sophisticated instrument will help to cope with atmospheric
abberration which can negatively influence the quality of astronomical
images. It eliminates color deviation caused by atmospheric distortion of
the light rays. The ASH dispersion corrector will significantly improve the
quality of (planetary) astronomical images.
This corrector contains two broadband antireflection coated wedge
prisms, which can be rotated against each other.
At 0° angle the effect is zero, and at 180° you have the maximum effect.
