先进的无昏迷LX200光学管配有Meade的超高透射涂层（UTHC），超大尺寸的低膨胀硼硅酸盐主反射镜，Schott Borofloat玻璃校正板，衍射极限光学元件，Losmandy风格的燕尾形和防尘罩。

先进的无昏迷（ACF）光学系统为大多数业余爱好者带来了*高水平的光学性能。使用Meade*家设计，ACF光学器件可实现与Ritchy-Chétien系统相当的非平面性能-平坦的视场，减少的像散和消除的衍射峰-仅需一小部分价格。结合Meade的超高透射涂层（所有LX200-ACF系统的标准配置），您将拥有*级的光学元件。

所有LX200型号均具有主镜锁定机制，可有效防止在长时间曝光天文摄影或观察过程中主镜移动。旋转位于望远镜主对焦旋钮正上方的锁定旋钮，而渐进张力主锁定则完全消除了在视觉，摄影或成像应用中由于镜移动造成的任何残留图像偏移。

14英寸LX200光学管组件＃0410-60-01的焦距为3556mm，焦比为f / 10，重量为57lbs。

Advanced Coma-Free LX200 Optical Tube comes with Meade's Ultra-High Transmission Coatings (UTHC), Oversized Low-Expansion Borosilicate Primary Mirror, Schott Borofloat Glass Corrector Plate, Diffraction Limited Optics, Losmandy-style dovetail, and Dust Cover.

The Advanced Coma-Free (ACF) optical system has brought the highest level of optical performance well within the reach of most amateurs. Using the Meade exclusive design, ACF optics achieve aplanatic performance — with a flatter field, reduced astigmatism and eliminated diffractions spikes — equal to Ritchy-Chétien systems, at a fraction of the price. Coupled with Meade’s Ultra- High Transmission Coatings (standard on all LX200-ACF systems), you have the ultimate in premium optics.

All LX200 models feature a primary mirror locking mechanism, which effectively prevents movement of the primary mirror during long exposure astrophotography or observing. Turn the lock knob located just above the telescopes main focus knob and the progressive-tension primary lock completely cancels any residual image shift due to mirror movement during visual, photographic, or imaging applications.

The 14" LX200 Optical Tube Assembly #0410-60-01 has a 3556mm focal length, an f/10 focal ratio, and weighs 57lbs.
