Precautions Optical Equipment

Precautions for Using Microscopes – Optical Equipment

• Never strain, twist, or drop objectives or other optical components. Optics for
  polarization microscopy are especially susceptible to failure due to mishandling.
• Never force the focus controls of the objective or condenser, and always watch lens
  surfaces as they approach the specimen. This is especially important for highpower
  oil immersion lenses.
• Never touch optical surfaces. In some cases, just touching an optical surface can
  remove unprotected coatings and ruin filters that cost hundreds of dollars. Carefully
  follow the procedures for cleaning lenses and optical devices.
