The operation principle explanation:
The radiant light that the xenon lamp xenon arc sends converges through the reflection of ellipsoid condenser and with given wrapping angle, changes optical axis direction through plane mirror again and projects on second focal plane of ellipsoid condenser, forms an irradiation profile in a big way.The element lens array symmetry division that this irradiation profile in a big way is positioned on ellipsoid condenser second focal plane becomes a plurality of little irradiation ranges; The element lens array superposition that is configured projection lens then is imaged onto the infinity; By projection lens's outgoing collimated light beam, form an irradiation range uniformly.The collimated light beam of projection lens's outgoing, projects near the back focal plane of collimator objective with certain illuminating aperture angle (being angle of collimation) through the collimator objective assembly, forms an irradiation face uniformly.
