In optical power meters, especially those integrated with spectrometers or optical spectrum analyzers, the slit acts as a narrow aperture that shapes and limits the light reaching the photodetector . By controlling the width of the slit, the instrument can:
Slits are typically micrometer-scale openings, ranging from a few micrometers to several hundred micrometers in width, with heights usually between 1–2 mm . The width must be carefully chosen based on the measurement requirements:
In instruments like optical spectrum analyzers, the slit works together with monochromators, gratings, and detectors. The slit defines the input “object” for the optical system, and the focusing optics project the slit image onto the detector. The final spectral resolution depends on the slit width, optical magnification, and any additional image broadening caused by the optical design .
