APM Telescopes New Ceramic Safety Herschel Prism Released Just in Time for 2017 American Solar Eclipse

APM’s new 2-inch Ceramic Safety Herschel Prism operates on the principle that only a small portion – approximately five percent – of the incident light is used for the actual observation. Herschel Prisms of the classic design guide the unused and incomparably larger, more energetic portion of light through the housing to form a focal point outside of the prism.

But even far behind that focal point, the light concentration remained very intense, so that caution had to be exercised to prevent an inexperienced observer from accidentally looking into that too-bright output light beam.

APM’s refinement of the Herschel Prism incorporates a ceramic light trap, an integrated multicoated ND3 filter, plus a removable, multicoated polarizing filter, which refinement eliminates the danger of inadvertent observation of the output  beam. The result is a white-light system that is perfectly safe for both imaging and visual observation of the Sun. The inclusion of the 2-inch polarizing filter allows adjustment of image brightness by simply twisting the filter via a lever.

When viewing the 2017 Solar Eclipse, this system is not only safe, but also produces an image of higher quality than that produced by most front-mounted white-light solar filters, with greater sharpness and higher contrast which allows for viewing and imaging at higher magnifications.

The new Ceramic Safety Herschel Prism also features APM’s Fast-Lock system for precise, automatic centering of inserted accessories to the optical axis. The device even ships in an included metal carry case with a die-cut foam insert that provides room for other accessories.

APM’s new Ceramic Safety Herschel Prism is priced at €395, including VAT, or €331.93 for export. For more information, please visit www.apm-telescopes.de.
