摘 要
|
中国科学院南京天文仪器研制中心在20世纪80年代研制35cm太阳磁场望远镜滤光器取得巨大的成功，其在双折射滤光器领域内的水平，
已被国际太阳物理界公认。 1989年以来，
已向日本和韩国出口了11台复杂而昂贵的Lyot滤光器，并已在有关国立天文台和天文馆投入常规观测。
最近， 还为国外客户修复3台Lyot滤光器，它们都是德国和法国在30年前生产的。

Abstract
|
Since 1960s, Nanjing Astronomical Instrument Research center of CAS
have been developing the birefringent filters for China solar
observatories, the most famous one in the world is the 0.15Å(0.12Å)/5324
Å (4861Å)
filter for the 35cm Solar Magnetic Field Telescope of the Huairou
Solar Station of Beijing Observatory. The big success in the field of
Lyot filter has been proved by the international solar physics circle,
since 1988, Japanese and Korean Astronomers have been paying a lot of
orders for making Lyot filters from China, up to now we have exported
11 sets of such sophisticated optical instruments, they have been used
for routine solar observations in the observatories and planetariums
in the two countries. We also begin to repair old Lyot filters made by
Germany and France from foreign countries, as India and Germany. |
