Coarse and Fine Adjustment
 
109
  • Includes 42mm plano-concave mirror.
  • NOTE: With bright artificial or natural light, mirror model will provide very adequate illumination. However, if light conditions are poor, it is necessary to incline the microscope on its inclination joint for the mirror to catch sufficient light. For a poorly lit environment, we recommend selection of 109-L or 109-LED, with electric illuminator.
 
109-L
  • 115v 15 watt substage illuminator with on/off switch permanently factory mounted.
