William Optics 1/10λ mirror diagonal
William Optics 全新一代超高精度二吋天體稜鏡 ( 2" Dielectric Carbon
Fiber Diagonal + FREE SCT ring! ) 外觀延續前 一代現代大方造型，在結構主體採
鋁合金外框，側面用碳纖包裝，結構輕便、穩固耐用，全新一代接目鏡端採流線化造型，更增添造型上的科技感。
天體稜鏡不像傳統稜鏡成像時需經過數次透射、反射易有像品質不良情形出現。William
Optics全新一代超高精度二吋天體稜鏡 ( New Generation 2" Mirror Diagonal )採用比前一代更高精度 ( 1 /
10λ)、更高反射率鏡面 ( 99.0% )，
提供成像時最佳的成像品質，最適合搭配高精度天文望遠鏡進行如行星、月面等高倍率天文觀測，或是對成像品質要求極高的數位望遠鏡攝影，已成為天體觀測或數位望遠攝影時不可或缺的配件。
使用William Optics 全新一代超高精度二吋天體稜鏡( 2" Dielectric Carbon Fiber
Mirror Diagonal )搭配二吋超廣視角視目鏡 ( Super wide angle eyepiece ) 目視視角可達
85度讓您享受一次看個夠！」「一次看個清楚！」的舒適體驗。

If what you are looking for is
the highest achievable brightness, contrast and sharpness during critical
observations with high-end instruments, WO 90° 2" mirror Dielectric star
Diagonal is your choice. This dielectric diagonal features 100% real carbon
fiber side plates that add that touch of class your scope deserves. A premium
product at a discounted price. Check it out and see the difference between a
"budget diagonal" and a real bargain!
Free SCT adapter with each diagonal
Included in the price you will have an SCT ring that makes your diagonal work on
SC telescopes or our ZS66 series as well! Get one diagonal, use it on ANY
telescope! This alone is worth US$ 40 and will save you the costs of buying
another diagonal!
Top-Notch Performance and brightness
• Dielectric coating allows 99% reflectivity.
• 10mm thick substrate flat for optimal image stability.
• Polished to 1/10th wave accuracy*.
• Accurate design guarantees constant alignment. No further alignment needed.
Meticulous Craftsmanship
• 2” to 1.25” eyepiece adapter included.
• Lock screw for eyepiece/adapter.
• Big, knurled thumbscrews easy to turn even with gloves on.
Strikingly Beautiful
• Patented, elegant design*.
• High-quality machining out of the best aluminum.
• Internally antireflection threaded for highest contrast.
Superbly Constructed
• Compression rings (both on diagonal and adapter) to prevent barrels’ marring.
• Internal safety stop prevents 2” barrels from hitting the mirror.
Why W.O. diagonals do not feature an Adjustable alignment system?
•Having an adjustable alignment system is an admission that the diagonal can go
out of collimation due to poor mechanical construction. Thanks to the patented
design of WO diagonals, you will always have a diagonal that performs perfectly
like the first day you got one!
