Baader T2 BBHS is a great quality diagonal mirror with T2 threads on both ends and it provides greatest reflectance over most spectral range from 390 to 2000nm. Much higher in brilliance than cheap dielectric coatings thanks to BBHS (Broadband Hardsilver) coating with dielectric protective overcoating.
