Lunt Solar White Light Herschel Wedge - 2"
Lunt White Light Solar Herschel Wedge
The Lunt Wedge contains a fully integrated heat trap. The heat is allowed to pass thru the prism and is directed to the rear end of the Wedge. At the rear of the Wedge you will note a red disk. This disk serves to absorb the heat and prevent internal reflection of the residual light. The fins act to pull cooler air thru the rear part of the system as the heat sink heats up. This convection will keep the heat sink from getting too hot.
