Product Description

PrimaLuceLab XP 90° 31.8mm Dielectric Diagonal

PrimaLuceLab XP dielectric diagonal mirrors have raised the bar when it comes to optical accessories thanks to their high optical and mechanical quality at a great price. When you point a telescope with back focus (such as a refractor or a Schmidt-Cassegrain) at zenith (ie vertically), the eyepiece is in an exceptionally difficult position for proper observation. The PrimaLuceLab XP dielectic diagonal mirror positions the eyepiece in a more comfortable position while retaining 99% reflectivity!

Overview:

  • Dieletric mirror to ingrease images brightness: standard mirror diagonals use mirrors with reflectivity around 94% then, with our XP mirror diagonal, you will have 5% more light with your telescope!
  • Lambda/10 correction mirror for high contrast images: while classic mirror diagonals reduce image's contrast (an effect particularly visible at high magnifications), our XP dielectric mirror diagonal uses a high precision mirror (lambda/10) to keep the image contrast high.
  • Quality built: our XP mirror diagonal are completely metal built with high quality materials. 31,8mm accessories inserted in the mirror diagonal are blocked with a brass ring to avoid damaging the inserted accessory.
  • 31.8mm filter thread: on the 31,8mm nose (that lets you connect the mirror diagonal into the 31,8mm focusers) there's a thread to connect 31,8mm diameter filters.

NOTE: Picture shows OTA and eyepiece which are NOT included!

XP 90° 31,8mm mirror diagonal (with LE Planetary eyepiece inserted in) connected to AIRY APO80 telescope's focuser.
 
The XP 90° 31.8mm dielectric diagonal is made entirely of aluminum with anodized finish and it fits in all 31.8mm eyepieces and provides the connection for 31.8mm diameter accessories. On eyepiece side it offers a closure with brass ring to avoid damaging the inserted accessory (other diagonal secure the accessory directly closing it with a screw that marks the barrel).
