    PlaneWave 17″ Optimised Dall Kirkham Telescope

    Please note pricing on our website is not final, Please contact us for best pricing and availability.

    The PlaneWave 17″ Optimised is a Dall-Kirkham optical design with coatings that are optimized to transmit in infrared or ultra violet wavelengths.  It is diffraction limited across a 20mm image circle at the focal plane.  There are no refractive lens, only reflective components to the design.  For IR application, reflectives coatings are a protected gold which give better than 98% reflectivity from .65 micron (650nm) to 5 micron (5000nm).  This design is ideal for infrared astronomy or LIDAR applications.  UV optimized coatings can also be used at an additional cost.

    Carbon Fiber Truss Design Minimizes thermal expansion which causes focus shift with changes in temperature
    Dovetail expansion joint Allows for the difference in thermal expansion between carbon fiber and aluminium. The expansion joint allows the aluminium dovetail expand and contract without stressing the carbon fiber lower truss
    Cooling Fans Three cooling fans ejecting air from the back of the telescope and four fans blowing across the boundary layer of the mirror surface. This helps the telescope to reach thermal equilibrium quickly. The fans are controlled by a computer if the optional Electronic Focus Accessory (EFA Kit) is purchased.
