Baader Planetarium Dielectric Mirror Telescope Diagonal with ClickLock - CLDIAG-2

Baader Planetarium 2 Inch Dielectric Diagonal    With their ground-breaking introduction several years ago of the all-dielectric 2" Dielectic star diagonal, Baader Planetarium brought mirror star diagonals into the 21st century.  The new 2" Clicklock Star Diagonal takes this innovation another step further.  Like its predecessor, the 2" Clicklock Star Diagonal uses the proprietary Baader Dielectric mirror coatings.  The Baader coating process eliminates the Achilles Heel that has plagued other all-dielectric mirror coatings - normally the multi-layer coating results in high surface stresses that  cause a star diagonal's mirror to warp as much as 1/2 wave, ruining the figure and distorting the optical wavefront.  Baader's proprietary coating process maintains the 1/10 wave mirror surface accuracy - After Coating!     Baader's Dielectric coatings deliver an amazingly high 99% photo-visual reflectivity along with an extremely hard durable surface.  The Maxbright mirror coatings will last
