Web18 nov. 2024 · Interferometers can measure objects with extreme accuracy. They work by taking a beam of light and splitting it into two equal halves using a beam splitter, effectively a piece of glass thinly coated with silver. When light is shone on the beam splitter, half the light passes through and half is reflected back. WebIn difference to interferometer, confocal optical microscope VKX-1000 is combining white light with a laser light source. Laser scanning confocal microscopes are able to scan a surface and collect both an optical image and high-resolution surface data. Nanometer-level heights can be measured by analyzing the intensity of the returned laser ...
