Microscope: 50X Microscope, 100X Microscope, 100X Microscope w/light. These high quality microscopes allow critical inspection of stencil openings, coating, and stencil development. Applications: Evaluate screen stencil exposure to light and reveal undercutting (over exposure), or under-exposure of emulsion from incorrect exposure times. Helps process control of fine halftones or line work. Inspect for air bubbles in emulsion caused by incorrect rapid coating procedures. (Air bubbles form behind the mesh knuckles when emulsion is coated too fast with an emulsion coater.) For print inspection to fine tune registration or definition of fine details.
