AUC-294C Series Intelligent Trinocular Inverted Biological LED Microscopes

Tilting head and illumination column with coded optics, LCD status display and phase-contrast or LED fluorescence configurations

The AUC-294C Series is designed for comfortable, precise observation of cultured living cells, tissues and microorganisms. Both models combine NIS60 infinity optics, an intelligent coded quintuple nosepiece, automatic illumination management and a front LCD operating-status display.

The 5-35° tilting viewing head supports seated and standing operation, while the tilting transmitted-illumination column creates additional space for changing larger Petri dishes, flasks and culture vessels.

Important: the built-in LCD displays microscope settings such as magnification, illumination intensity and operating status. It is not a specimen-imaging screen. A microscope camera, monitor and imaging software are optional.

AUC-294C-I

Intelligent coded phase contrast

4× NIS60 LWD plan brightfield objective
PH10×, PH20× and PH40× NIS60 LWD plan phase-contrast objectives
Intelligent coded quintuple nosepiece
Automatic objective-specific illumination adjustment
Front LCD operating-status display

AUC-294CF-I

Intelligent coded LED fluorescence

4×, 10×, 20× and 40× NIS60 LWD plan semi-APO fluorescence objectives
Reflected LED fluorescence illuminator with fly-eye lens
Configurable with up to three LED sources and B, G and U filter blocks
Intelligent coded quintuple nosepiece
Front LCD operating-status display

Intelligent illumination management

Both models use a coded nosepiece that recognises the selected objective and can recall its preferred illumination intensity. This helps maintain consistent observation conditions, reduces repeated adjustment and limits visual fatigue.

Automatic objective-specific brightness adjustment
Light-intensity lock and unlock
Standby/sleep mode
Selectable automatic switch-off time
Transmitted and fluorescence source selection where fitted
LCD display of magnification, light intensity and operating status

Ergonomic tilting design

5-35° tilting Seidentopf viewing head supports comfortable observation when sitting or standing.
Tilting illumination column improves access when moving large culture vessels on and off the stage.
Left-side camera port reduces interference with routine controls.
100:0 or 0:100 light distribution directs all light to either the eyepieces or camera port.
Compact anti-UV body is suitable for work around clean benches.
