Optem Long Working Distance Objectives
Optem® Long Working Distance (LWD) Objectives are the perfect machine vision and industrial imaging solution for applications demanding higher magnification, resolving power and chromatic performance without compromising working space around your subject.
Optem M Plan APO Infinity-Corrected Objectives are available in 2X, 5X, 10X, 20X and 50X magnifications and provide flat-field imaging for both zoom and fixed magnification needs. These objectives are apochromatically corrected and designed for brightfield illumination.
Optem LWD HR Objectives are avaialble in 5X, 10X and 20X and designed to maximize NA for high-resolution critical inspection applications.
