PRODUCTION DEVICE FOR PROJECTION LENS, PRODUCTION METHOD FOR PROJECTION LENS, PROJECTION LENS PRODUCED BY THIS PRODUCTION METHOD FOR PROJECTION LENS, AND PROJECTOR PROVIDED WITH PROJECTION LENS
Projection lens 46 is a lens group 110 are sequentially arranged, and a lens barrel 100 in the optical path is set inside a lens barrel (100) perpendicular to third group lens 113 to the optical axis that are orthogonal to each other is located in a position adjusting opening (122A) is formed. Projection lens holding mechanism image the light emitting mechanism for introducing a test pattern image is formed in accordance with the light emitted from the 550, the light source device 521 to the projection lens (46) for holding the projection lens 46 to the lens adjustment position ( 526) and a projection lens (lens position adjusting mechanism 570, and a third group lens after adjustment for adjusting in accordance with the position of and detecting the projected image light 3 group lens 113 in the X-axis, Y-axis through 46) and a bonding fixture 580 for fixing the 113 adhesive.
