Lunt 2-Inch White Light Herschel Wedge / Solar Wedge
LUNT 2" WHITE LIGHT HERSCHEL WEDGE / SOLAR WEDGE
Herschel Wedges / Solar Wedges will be used to observe the sun with refractor telescopes in white light. Approximately 95% of the sun light will be suppressed by the Herschel Wedge. The remaining 5% can be reduced to the desired level by variable polarizing filters and/or strong gray filters. The difference between Herschel Wedges and normal front mounted filters is, that the filtering takes place just before the eyepiece or camera. This will provide a better contrast and sharpness of the solar image.

The advantages of the new LUNT Herschel Wedges:
- especially high-quality optical surfaces for very good contrast
- fully closed body with integrated heat trap
- no stray light escaping - so it is very safe
Only for use with refractor telescopes up to 150mm aperture:
Because the full energy and heat of the sun will be inside the telescope, we advise to use only refractors with a Herschel Wedge. The refractors must not have corrector lenses at the back. Optical elements like corrector lenses or secondary mirrors of reflector telescopes become very hot by the concentrated solar energy and could be damaged.
Tuning the brightness:
5% of the sun light are too much for observing the sun, the light must be dimmed even further. Because the Herschel Wedge produce polarized light, you can use a normal polarizing filter at the eyepiece or camera-adapter. By turning the polarizing filter the brightness will be reduced. The remaining light will be reduced sufficiently by the included ND 3.0 gray filter.
Polarizing filter not included, but available as an optional and recommended extra.
