Optical surface topography measuring device for e.g. lens of infrared camera, has measurement support having support surface on which optical part is placed, where support surface fits in elastically compressible cushion

摘要

The device has a measurement support (6) having a support surface (10) on which an optical part e.g. lens (1), is placed. The support surface fits in an elastically compressible cushion (15). The cushion is formed by a pressurized air chamber (33) that is delimited by an inflatable flexible layer (30). The support has a body (16) having an annular surface (12) on which the layer extends.
