从总体看，中国望远镜镜片的质量到底怎么样？
今天和别人讨论时，别人提到中国透镜的质量差。诸位有什么看法？这里附上原文：
Hi:
I'm curious about why Chinese telescope optics are sometimes not up to par as compared to Russian optics which in my opinion are better to some US optics and just near the Japanese quality.
The story is Russian/Soviet optics were made under better control for military purposes and now they are being put out world wide by a few known companies like LOMO ( Leningrad Optics Mfg. company ) but the Chinese seem to be having problems with their optics at times, they are also a military power and should have very good optics.
What would be the major problem here? Is it that China is "new" to the optical exporting area and try to get telescopes out faster or are they more or less in the "experimenting" stages of making telescope optics for "commercial" use. China does have astronomical observatories and I'm sure those telescopes would be of good optical quality, but for "amateur" scopes there must be some problem somewere in the manufacturing.

镜片不差。
日本和美国不少生产厂家直接进口我们国产的镜片组装成他们的器材。我们国家光学器材最大的问题在于镜片的组装不够精细结果造成比较严重的像差。目前一些小望远镜生产厂家使用劣质镜片和简易的组装方式制造出的镜子的确存在问题。但只要购买大公司正规化设计制造和检验的望远镜就不会存在问题。 有个朋友回答得比较详细，有牌子，有分析。感兴趣的可以看看http://www.v-galaxy.com/v5k/showtopic.asp?TOPIC_ID=1409&Forum_ID=1 中国光学工业的一个弱项是没有很好的异常色散玻璃
我想这也是制约发展的一个重要原因吧
国内厂家的机械加工水平也不高！
希望国内光学研究所及厂家多办一些实事，为国争光。早日开发出萤石等超色散玻璃，满足军事工业及民用工业的迫切需要和天文观测的要求。
我想军事上应该有了吧.
军事领域也许有了吧
