Slim LED Transmitted Light Illumination Base with Turret System Expands Observation and Contrast Options for SZX/SZ/MVX10 Microscopes

Users of Olympus’ SZX™ and SZ™ series stereo microscopes and the MVX10 fluorescence microscope can expand their observation capabilities thanks to a new slim 41.5 mm (1.6 in.) LED transmitted light illumination base. The base contains a unique, easy-to-use turret system that can be loaded with up to four cartridges. Nine cartridges are available, offering different observation methods, including brightfield, darkfield, polarization, and oblique, as well as three levels of contrast (low, standard, or high) for the brightfield and oblique illumination. Users can easily switch the cartridge by rotating the turret to quickly find the optimal observational conditions for their sample.

The LED lamp in the transmitted light illumination base provides several advantages:

Color stability: LED light maintains its color even when users adjust the brightness or zoom.

Easy to maintain: With an average life span of 60,000 hours, these LED lamps last longer than halogen bulbs.

Reduced operating costs: Power consumption of LED lamps is about half that of halogen light sources.

Low running temperatures: The low heat dissipation from the LED light in the slim base makes it well-suited for long-term observation of live samples and clean rooms, such as in semiconductor production plants, where temperature management is important.

Nine different cartridges can be selected to vary the observation method and contrast
