Optics
All VIEW systems use our exclusive Dual Magnification Optics System to provide accurate images under a wide variety of lighting conditions.
The Dual magnification optics system provides two internal magnification multipliers - "Low" magnification is a 1X multiple of the front lens, while "High" magnification is a 4X multiple. Both magnification images are always present; selecting one camera or the other determines the magnification image that is used for measurement. The choice of low or high magnification is instantaneous and requires no movement of any optical element so there is no change in calibration or datum references. This makes for a highly accurate and repeatable system.
The dual magnification optics system also provides a direct through-the-lens surface light, an optional Ronchi Grid pattern projection for increased focus resolution, and provisions for a through-the-lens laser for precise height and contour measurements.
The front objective lens may be selected for the application at hand. A lower magnification provides a larger field of view, while a higher magnification provides higher resolution. VIEW offers a choice of front lens magnifications including 0.8X, 1X, 2.5X, 5X, and 10X.
