Nikon’s new Eclipse 50i and 55i models were designed to provide an unsurpassed ergonomic and digital imaging microscopy system for users handling a high throughput of samples.

“The Eclipse 50i and 55i have exceptional optical capabilities, utilizing world-famous Nikon CF160 optics, and a new, advanced, stress-free design with a solid platform for routine digital imaging applications,” says Stan Schwartz, Nikon Instruments’ division manager of microscopy product marketing.

The stage handles of the 50i and 55i remain in a fixed position during use, allowing hand and body positions to remain constant and in line with the instrument. Both left- and right-handed versions are available, and the hard “alumite” coating on the stage creates a resistant surface, providing the durability needed in a busy laboratory.

The 55i employs a white LED illumination system, which is ideal for bright field applications. It overcomes the excessive heat and color temperature changes that occur with halogen light sources when changing from high to low intensity. The digital LED illumination provides a homogenous and bright distribution of illumination across the field for optimal viewing and digital imaging, with vivid, true-to-life colors. The LED is low in IR wavelengths for coolness, thus reducing eyestrain for the user. The 55i LED has a long life cycle and low power consumption, and it can run on lithium batteries.

An optional, new “ergo-view” one-touch nosepiece and objective changeover system has been designed for the i-series for use in cytological screening. It facilitates rapid switching between 10x and 40x magnifications, and it also includes an easy-to-use slide-marking function. When the “ergo-view” is used in combination with the 55i’s LED illumination, it automatically adjusts itself to magnification changes, enabling the user to view samples at a constant brightness.

The tilting/telescoping ergonomic head has an extended telescoping feature and can accept Nikon’s DSC tube, allowing easy and direct connection of the recommended Digital Sight family of digital cameras, creating a compact, ergonomic, and easy-to-use microscope-documentation system. The digital system can either stand alone or be integrated into a network, enabling flexible image management.

A new dedicated laboratory Epi-fluorescence illuminator with a four-cube position turret incorporates Nikon’s exclusive fast cube changer and lockout mechanism for quick and sure changes between wavelengths. This, together with the 50i/55i microscope, provides extremely bright, high-contrast, crisp, fluorescent images.

“For our microscope customers charged with handling and recording samples in high volume, the best in ergonomic comfort and view just got better,” Nikon’s Schwartz says.
