Mitutoyo G Plan Objectives - 20X or 50X
Description
Series 378 Objectives - G Plan Apo for Brightfield Observation
- The Mitutoyo 378 Series objectives have the world's longest working distance and an infinity correction optical system.
- These objectives provide flexible observation at high magnifications and independent correction of chromatic aberration.
- Long working distance objectives provide excellent clearance between the lens surface and the workpiece surface in focus, making it possible to observe features that are usually hard to bring to focus because of awkward projections.
- Specially designed objectives are also available with correction for near-infrared, near-ultraviolet, and ultraviolet, or for observing through LCD screen glasses.
- The mounting screw threads of objectives are designed to conform to JIS B-7141-1988.
- Glass Thickness (t = 3.5 mm) Corrected.
Note: Focal length and focal depth for objectives are specified at a reference wavelength of 0.55 µm irrespective of working wavelength.
Optimised for through-glass working
The G Plan Apo Series objectives are designed for observing a workpiece through glass (thickness = 3.5 mm).
