Biological Microscopes

Plan objectives for image clarity

Setting the standard for clinical inspection microscopes ultimately depends on image clarity. Olympus' choice of plan objectives ensures bright, clear observation images with excellent flatness and full compensation for chromatic aberrations.

Improved viewing contrast

The combination of UIS2 objectives with the fully multi-coated UIS2 eyepieces (WHN series), gives higher image contrast and a striking improvement in overall visibility. Stained specimens show greater clarity with a whiter background.

Even illumination to the edge of the visual field

Using original transmitted light diffusion simulation technology, Olympus developed a diffusion optical device which provides bright, even illumination from low to high magnifications.

Environmentally-friendly UIS2 optics

Recognizing the interdependence of optical excellence and care for the environment, Olympus makes all UIS2 objectives and WHN eyepieces from lead-free eco-glass. We will continue to seek new ways to incorporate this material into optical parts that have glass components.

Ideal color temperature for digital imaging

Because UIS2 optics' color temperature at both the eyepiece and on the CCD surface is closer to natural daylight (5500K), color reproduction on the monitor matches more closely to what is seen during observation.

Advanced, high-performance UIS2 optical system

Olympus' principal reason for replacing the popular and well regarded UIS optical system with its UIS2 successor is to meet a more diverse and demanding range of future needs. Olympus' infinity corrected optical system has the tube lens inside the observation tube, which prevents image deterioration even if other optical components and items of equipment are added in the parallel luminous flux. In addition, UIS2 flexibility provides greater freedom in system structure, even allowing equipment to be added in two tiers simultaneously.

Infinity-corrected optics

Infinity-corrected optics incorporates a parallel luminous flux along the light path. Even if a half-mirror (or other components) are inserted into the parallel luminous flux, there is no image retardation and no deterioration in image clarity.
