Surfaces to be bonded tested for cleanliness. Equipment includes commercial photoelectron-emission sensor. Inspected surface irradiated with ultraviolet photons from source in sensor head while anode in sensor head collects photoelectrons ejected from surface by absorbed photons. If intensity and spectrum of ultraviolet light and distance between sensor and surface held constant, then photocurrent varies according to amount and type of contamination.
