PURPOSE:To perform centering operation irrelevantly to the kind, size, thickness, etc., of a lens by applying an adhesive which has flowability after fitting the lens in a holding frame, oscillating the holding frame with an ultrasonic wave before the impregnation and curing of the adhesive, and setting the adhesive after the alignment of the lens. CONSTITUTION:The lens 10 to be held is inserted into the fitting part of the lens holding frame 11 and the adhesive is applied properly between the lens 10 and holding frame 11 through a dispenser to impregnate. Then, an ultrasonic wave generator 13 is driven to oscillate an oscillation table 14 by an oscillator 15 at a frequency of 55kHz. The axis O1 of a lens barrel 11 is aligned to the optical axis O2 of the lens 10 through the cooperation between the oscillation energy of the ultrasonic oscillating operation and the surface tension of the adhesive 12, and the lens 10 and lens barrel 11 are aligned automatically to each other. Then, the adhesive is irradiated with ultraviolet rays and set. |
