UIS Objective Lens
After the Second World War, Olympus developed various objective lens series, including the Plan series, MPlan series, and the LB series of long barrel objective lenses. The company also launched infinity corrected (IC) long barrel objective lenses for industrial applications, further expanding its lineup.
In 1988, Olympus took the momentous decision to switch all its microscope models to the new universal infinity system (UIS) optics. The new UIS optical system was based on the concept of an ideal microscope to meet all needs. It incorporated the following features:
- World-class resolution and contrast for all observation methods.
- Infinity optics, unifying the design concepts for biological and industrial systems.
- Universal objective lens lineup, as this single objective lens series can be used for all types of observation methods.
- Expanded field of view of 22 for standard observations (the field of view is a unit expressing the breadth of view).
- Improved operability by expanding the range across which the objective lens can move.
- Excellent scalability of modular components.
The development and manufacturing teams at Olympus had given their all on this product. When they finally completed their work, they had achieved a novel design and reliable product quality; developed thin-film coatings (multiple coats) and more appropriate glass materials; and implemented automated lens processing methods to lower costs.
The UIS objective lens series was launched in 1993. These lenses contributed to greater product appeal in the AX, BX, CX, and IX series microscopes.
