Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 55 words
Optical instrument with a chassis of ceramic, on which several optical components are attached in a position adjusted to one another, characterized by the fact that for obtaining a good strength and a permanent precise holding of the optical components at least the parts of the chassis essential for this purpose exist of compacted ceramic.
Claim 2
Dependent Claim 55 words
Optical instrument with a chassis of ceramic, on which several optical components are attached in a position adjusted to one another, characterized by the fact that for obtaining a good strength and a permanent precise holding of the optical components at least the parts of the chassis essential for this purpose exist of compacted ceramic.
Claim 3
Dependent Claim 27 words
Optical instrument according to Claim 1, characterized by the fact that the coefficient of thermal expansion of the compacted ceramic is equal to that of optical glass.
Claim 4
Dependent Claim 24 words
Optical instrument according to Claim 1 or 2, characterized by the fact that the chassis is developed as a three-dimensional torsionally- resistant hollow structure.
Claim 5
