These objectives are world-renowned for setting the standard of excellence for long working distance microscope optics.
They have achieved the best combination of working distance and optical performance by using a new approach¡ªavoiding outdated conventions used by competitors.
Making the objectives larger and longer has made the designs easier (95mm parfocalization length).
For an infinity corrected system, a secondary (or tube) lens is required.
All stated magnifications are based on a tube lens focal length of 200mm.
Works with all Mitutoyo parts and can be placed directly in a system currently utilizing Mitutoyo objectives.
