  • Page 12 Focus Using the scope without the video function ① Completely lower the light path selector lever (① in Fig.22) to view. It is recommended that you begin with the 10x objective, to avoid contact with the specimen. Begin with the mechanical stage raised close to the objective and slowly lower the stage to obtain the best focus.
  • Page 13 Using the ND Filter Knob The ND Filter is interlocked with brightfield (BF) light path. It can be switched from engaged to disengaged according to the mirror selector lever (① in Fig.25). You can reduce the glare with the ND filter when you switch from darkfield (DF) to brightfield (BF).
