The substrate of
the lighten refrlection-mirror

Success Case A：Lighten the reflect scope’s
weight of aerospace remote sensor
In 1991, A research group led by our senior engineers
researched and manufactured a reflect scope of aerospace remote sensor successfully
for the former 508 institute of Chinese Aeronautics and Space
Administration.
With the increasing of the size and mass of the aerospace
instrucment, the
cost and complexity are increased as well a lot. So people
have do research on the smaller and l ighter
remote sensor. The former subject, that the 508 institute of Chinese Aeronautics
and Space Administration broached are designing and
making large reflect scope that can overcome the deformation
of self-weight and temperature variation. The technology group
completed the demonstration of choosing the raw material of the
mirror in a short time. Then resolved design and analysis work about how to make the round reflect
mirror lighter with aht finite element method. Finally, they succeed in lightening this large
reflect mirror under the requirement of strength, deformation and temperature variation. The mass of the mirror
was reduced to 51 percent.
This project breaks new ground in lightening aerospace remote
sensors in China.

Success Case B：Beam-splitting prism of
the aerospace remote camera
From 2000, our company took part in important national
aerospace project. Our company takes charge of designing and manufacturing the beam-splitting prism of an
aerospace remote camera. Depending on our own technology force
and hark working, we completed a series missions of researching
and manufacturing beam-splitting prisms. As perfect
performance and high quality products, we gained confirmation
and appreciation from other companies. We have ability to
undertake design and manufacture high quality and hith
technology.
The main parameters of these beam-splitting prisms are as
following: geometric dimension tolerance +/-0.02mm, length: 106 mm,
vertical tolerance: less than 15 seconds, angle tolerance:
less than 10 seconds, surface quality: 1/2 wavelength (the
local error less than 0.1)

64
degree roof prisms, single prisms, biprisms
and tetrahedral faces mirrors |
Success Case C：Long-term cooperation
with WENTER International Company Of The U.S.A
During 1996~2003, WENTER Company of the U.S.A. asked our
company to research and manufacture some prisms for them: high quality 64 degree
roof prism, a serials of complex single prisms, biprisms
and tetrahedral faces mirrors,etc. For their requirements,
our engineers chose high qualitity BK7 glass puoduced in China.
At last these products achieve the tolerance of the 64 degree roof
angle less than six seconds, the tolerance of the right
angle less than four seconds. And the second optical parallelism
is less than four 4 seconds. Now, all these products achieve
batch production and gain compliment from wide customers. |
