Wider Aperture Optics -- 32 mm wide apertures on the telescope and collimator provide more light for brighter and sharper images. Rack and Pinion Focusing -- On both the telescope and the collimator. Focusing is easier and more precise. Rotatable Table -- For greater flexibility in measurements. Turn the table by hand for coarse adjustments. Use the fine lead screw for delicate adjustments. The Collimator -- High-quality, large-aperture optics with a 6 mm long slit of adjustable width. The collimators can be independently focused, leveled and aligned. The Telescope -- High-quality, large-aperture optics plus a 15x Ramsden eyepiece with a cross-hair graticule. The telescopes can be independently focused and aligned. Precision Ground Bearings -- The main bearings are ground as a single unit, so the movement is exceptionally smooth with virtually no backlash. This is essential for precise positioning. Vernier Scale -- For precision measurements. Magnifier -- For reading the Vernier Scale. Prism -- Dense Flint Glass Prism with holder.    科學教育首頁 最新消息 活動快訊 產品資訊 技術支援 聯絡我們 好站連結 電子報 網站地圖     回國揚
