Olympus has taken this one step further with the CKX41 developing a modular design approach with the capability of a fluorescence illuminator for GFP; documentation of images with digital imaging and video monitoring. The CKX41 is routinely used for checking cell viability in petri dishes, culture flasks, and multi-well plates.
A binocular tilting tube, which allows observation while standing, and a trinocular observation tube which is compatible with various video cameras are available. Numerous accessories make it easy to upgrade the CKX41 according to need.
CKX series microscopes make cell checking quicker and easier than ever —because they are simple to operate, require minimal optical adjustments and capture the best possible observation images with outstanding efficiency. Use of a tilting observation tube, which allows the user to make observations while standing, is an especially convenient feature. In addition, the compact design allows installation right beside the incubator, improving safety and saving time spent on carrying specimens elsewhere for observation. Multiple observation methods are supported, and the range of applications has been further increased. The CKX series: designed to make routine cell checking quicker, easier and more efficient.
The UIS2 optical system combines with the simplicity of the light path and the imaging excellence of a relay lenses to maintain the highest possible image intensity and to arrive at the highest optical correction level. Thanks to this feature, the UIS2 infinity-corrected optical system deliver unsurpassed resolution and contrast. In addition to improved image quality, the maximum field of view has been extended to F.N. 22. This allows the use of various observation tubes provided for upright microscopes (patented, CKX41 only).
Incorporation of the world-renowned Olympus UIS2 optical system in the CKX series makes a dramatic improvement in flatness for 10 to 15% and enables very clear, high contrast images to be obtained up to the edge of the field view.
The UIS2 phase plate adjusts the contrast according to the thickness of the cell culture, producing higher contrast images than those obtainable from conventional systems.
The PHC objective is minimally affected by surface tension of the culture fluid, which can compromise clarity at the image periphery. Easier multi-well observation is one of several benefits. Combined with the improved flatness resulting from the use of UIS2 optics, this feature facilitates clear observation of cells even at the edge of the container.
The advanced Olympus UIS2 optical system maximized the advantages of infinity correction. Light travels through the body tube as parallel rays as it passes through the objective. These are focused by the tube lens to form a completely aberration-free intermediate image. Attachments can be added between the objective and the built-in tube lens in the observation tube without any magnification factor alterations to total magnification. Additional correction lenses are not required The UIS2 optical system delivers optimum image quality with any configuration.
