Mob Microscope Objective Wavefront Aberration Measurement Instruments Mob10
High-resolution microscope objectives require good geometric optical design and wavefront control from physical optics, especially at high magnification and numerical aperture where higher-order aberrations are large. Image quality is evaluated using spherical, chromatic, and coma aberrations as well as wavefront aberration; the source's ru/4 Rayleigh criterion is a general evaluation standard. The Mob objective wavefront instrument is a Twyman-Green laser interferometer that treats the objective as the test sample for wavefront measurement and computer-aided alignment, monitoring results after adjusting lens spacing or decentration. Universal objective interfaces enable rapid switching in batch production.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
