QUIJOTE CMB 实验旨在表征 10-30 GHz 频率范围和大角度范围内 CMB 的偏振。它将安装在泰德天文台，遵循宇宙微波背景各向异性小组过去开发的项目（特内里费岛实验、IAC-Bartol实验......）并且目前正在运行（VSA、Cosmosomas）。 QUIJOTE CMB 实验将由两台望远镜组成，这两台望远镜将安装在一个已经建造好的独特外壳内。两台望远镜的布局均基于支撑主镜和副镜的经纬仪安装座，该主镜和副镜以偏移格里高利龙方案布置。使用类似工业的制造技术，例如砂型铸造、数控加工和用于对准的激光跟踪仪测量，提供了微波观察所需的性能。快速建造方案加上这些制造技术的使用，使得望远镜的光学机械装置在 14 个月内就可以设计和制造出来，并于 2008 年 12 月交付并最终启动。
The QUIJOTE CMB experiment aims to characterize the polarization of the CMB in the frequency range 10-30 GHz and large angular scales. It will be installed in the Teide Observatory, following the projects that the Anisotropy of the Cosmic Microwave Background group has developed in the past (Tenerife experiment, IAC-Bartol experiment...) and is running at the present time (VSA, Cosmosomas). The QUIJOTE CMB experiment will consist of two telescopes which will be installed inside a unique enclosure, which is already constructed. The layout of both telescopes is based on an altazimuth mount supporting a primary and a secondary mirror disposed in a offset Gregorian Dragon scheme. The use of industrial-like fabrication techniques, such as sand-mould casting, CNC machining, and laser tracker measuring for alignment, provided the required performances for microwave observation. A fast-track construction scheme, altogether with the use of these fabrication techniques allowed designing and manufacturing the opto-mechanics of the telescope in 14 months prior to delivery for final start-up in December 2008.
