This limited edition leverages a 1\/10 lambda glass-ceramic mirror with a Broad Band Hard Silver (BBHS®) coating to achieve 98-99% reflectivity from 390 to 2000 nm. The entire optical system is housed within a precision-adjustable CNC-milled body with an optical length of 112mm, connecting via M48, M55, and 2\" threads.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eA 60-Year Legacy: The German-Made Vantablack® Anniversary Edition\u003c\/h3\u003e\n\u003cp\u003eTo celebrate its 60th anniversary, Baader Planetarium has created a special edition of its 2\" BBHS® mirror diagonal. This limited edition is more than a cosmetic update: its purpose is to suppress internal reflections and stray light even more effectively. The housing components are manufactured on Baader's own CNC machines, the optics are polished and coated in Germany, and final assembly, adjustment and quality testing take place at Baader's facility in Mammendorf.\u003c\/p\u003e\n\u003cp\u003eEach anniversary diagonal is presented in an elegant, black-lacquered beechwood case, specially manufactured in Austria from locally sourced wood. This collector's box provides stylish, lasting protection for a unique piece of astronomical equipment built to commemorate a six-decade legacy of precision engineering.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eVantablack® Meets BBHS®: 98-99% Reflectivity and Higher Contrast\u003c\/h3\u003e\n\u003cp\u003eThis diagonal combines two advanced coatings for an uncompromising optical experience. The interior surfaces are coated with Vantablack® 310, an ultra-black material originally developed for aerospace that absorbs stray light more effectively than a conventional matte-black coating, helping to preserve image contrast and the finest details.\u003c\/p\u003e\n\u003cp\u003eThe mirror itself features Baader's Broad Band Hard Silver (BBHS®) coating, which delivers 98-99% reflectivity across a vast spectral range from 390 nm to 2000 nm. Unlike standard dielectric coatings that are optimized for a narrow visual spectrum, the protected silver layer of BBHS® provides a brighter image, richer color saturation, and superior performance well into the infrared.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e1\/10 Lambda Glass-Ceramic: Fast Temperature Adaptation\u003c\/h3\u003e\n\u003cp\u003eThe substrate for the BBHS® coating is a glass-ceramic material with an exceptional surface accuracy of 1\/10 lambda.

This allows the diagonal to be precisely collimated, just like a high-quality refractor objective. While every unit is perfectly aligned at the factory using a 3-point system on an optical test bench, this adjustability is invaluable for advanced users building custom optical systems, such as binocular telescopes, that require perfect alignment between components.\u003c\/p\u003e\n\u003cp\u003eFor standard use, you will not need to alter the collimation. However, should you choose to, please note that changing the alignment voids the warranty on the factory collimation only; all other warranty coverage remains unaffected.
