OM150 Enhanced Focusing Coupled Triplet System

OM150 Enhanced Focusing Coupled Triplet System

The OM150 is an enhanced focusing coupled triplet system comprising three OM50 lenses, delivering submicron performance with high beam transmission.

Features & Specifications

  • Mounted on a precision micrometer controlled table for easy alignment: 5 µm vertical and horizontal, and 50 µradian rotational alignment
  • With large demagnification parameters in both horizontal and vertical planes, submicron performance with high beam transmission (100 pA) is routine
  • Using precision Hall effect probes to measure the magnetic field generated between adjacent poles for a particular beam focus, then this focus can be generated easily at a later stage by reproducing the lens magnetic fields
