Spot PhotoMeter

A spot photometer captures light from a specific small area through an optical lens, converts it into an electrical signal via a sensor, and measures the brightness value. It is used to detect the local brightness on surfaces of materials such as coatings and plastics, ensuring visual consistency in applications like color difference control in printed materials and paper whiteness inspection.
Selection
When selecting, consider matching the measurement aperture to the size of the object being measured, ensuring the measurement range covers the sample's brightness levels, and verifying that the observation angle complies with industry standards. Calibration should be performed using a standard whiteboard. Portable models are suitable for on-site inspections, and connectivity to software allows for data recording. Pay attention to shielding from ambient light and ensuring the stability of the instrument.
