    For solar white light imaging and white light visual observing. The APM White Light Wedge comes with a built in ND3 filter which allows perfectly safe imaging or visual observing of the Sun

    The function of the Herschel prism (also called Herschelprima) is based on the principle that only a small part (approx. 5%) of the incident light is used for the actual observation. The part, which is incomparably larger and also energetic, is guided through the housing and forms a focal point outside the prism. Even far behind this focal point, the light concentration is still very intense, so that (with older prisms) caution had to be exercised, so that no inexperienced observer would accidentally look into the output light beam.

    The APM Herschel prism is equipped with the ceramic light trap, an multicoated  integrated multicoated ND3 filter and (removable) multicoated  polarizing filter. 

    The sun can be safely observed with the APM Herschel Prism.The image brightness can be adjusted by twisting of the 2 "polarizing filter by rotating the 2" eyepieceholder from  outside  . Thus, the Herschel Prism can be used both visually and also photographically same good!

    The clear optical aperture  is 46mm!

    The use of the Herschel prism (in comparison with film filters) for sun observation is not only more safe , but also of better quality. The image  has more  contrast, imore sharpness  and allow higher magnification. 

    Important note: The application of the Herschel prism is only suitable for refractors and schiefspieglers .

    The Production version has a white body !
