collimating mirror वाक्य

उदाहरण वाक्य

1. One such application is high-resolution spectrographs that have large collimating mirrors ( ideally with the same diameter as the telescope's primary mirror ) and very long focal lengths.
2. Symmetric off-axis reflections from a single collimating mirror are employed to remove aberrations : the spatial resolution is limited by the telescope and the spectral resolution by the grating and aperture characteristics.
