Abstract:
Micro-pore optics (MPO) has been employed in space x-ray telescopes for
large field-of-view observations. For x-ray focal plane detectors with visible photon sensing capability, the optical blocking
filter (OBF) on MPO devices is critical for preventing signal contamination by those photons. In this work, we designed a piece of
equipment to measure the light transmission with high accuracy. The transmittance test results of the MPO plates meet the design
requirements of less than 5×10 −4 . Based on the multilayer homogeneous
film matrix method, we estimated possible combinations of film thicknesses (with alumina) that show a good agreement with the
OBF design.
