N-PLAN Achromatic Objectives

Achromatic objects ensure versatile and reasonable priced entry-level lenses for brightfield.

They are specially designed to achieve optimal contrast and thus maximise yield on the instrument.

100X with water – A new frontier in education

Same objective for oil and water use

  • Oil represents the best media for high numerical apertures
  • Water combines relevant results with convenience
  • Water is recommended especially for educational purposes

High Eyepoint Eyepieces

These eyepieces are designed in such as way that the exit pupil is further away from the eye lens than standard eyepieces, being well suited for students wearing glasses

They are specially designed to achieve optimal contrast and thus maximise yield on the instrument.

X-LED Lighting – Only available at Optika

Powerful and uniform Illumination

  • Incomparable light intensity, exclusive lens and collector design
  • Constant pure-white colour temperature at all intensity levels
  • Unmatched colour fidelity and brightness of your specimen

Money & energy saving
