Description

APM 2 Inch Solar Herschelwedge

APM 2 Inch Solar Herschelwedge features an integrated ND3 filter which allows for perfectly SAFE solar white light imaging and visual observing.

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 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.

APM Herschel prism is equipped with a ceramic light trap, an integrated multi-coated ND3 filter, APM Fastlock eyepiece clamp, and (removable) multi-coated polarizing filter. Image brightness can be adjusted by twisting of the 2” polarizing filter by rotating the 2” eyepiece holder from outside. Thus, the Herschel Prism can ideally be used visually and photographically.

With a clear optical aperture of 46mm, the use of the Herschel prism, in comparison with film filters, for solar observation is not only safer, but also of better quality. Images will have more contrast, razor sharpness, and allow higher magnification.

Important note: The application of the Herschel prism is only suitable for refractor and schiefspiegler telescope models.
