Abstract
PURPOSE:To accurately perform adjustment, which maximizes the shielding ratio, in a short time by independently rotating a pair of permanent magnets from the external after setting optical components into these permanent magnets. CONSTITUTION:A permanent magnet 2 is fixed in a holder case 1 and a polarizing element 3 and a Farady rotator 4 are set in this case 1, and a permanent magnet 6 is fixed in the other holder case 5 and an analyzer 7 is set in this case 5, and these permanent magnet holder members are engaged with each other and are rotatably joined integrally. The semiconductor laser beam is made incident on this optical isolator constitution body with cases 1 and 5 rotated to determine the position where the reverse direction loss is maximum, and they are fixed with an adhesive. Thus, the adjustment to maximize the shielding ratio is accurately performed in a short time.
