Orthogonally oriented imaging spectrometers generate duplicate diffraction profiles to verify detections, reducing false positives from optical clutter.
A modular optical coupling mates via kinematic interfaces to constrain lateral displacements and maintain beam alignment.
Removable probe cover uses a camming surface to flex snap-on fasteners for secure attachment.
Off-axis parabolic mirror collimator aligns fiber axes to reduce angular sensitivity in optical measurement systems.
Concentric diffraction patterns on a substrate diffract extreme ultraviolet light to achieve high transmittance and resolution.
Controller acquires observation window environment information to correct optical property parameters, eliminating position-dependent measurement inaccuracies.
