AxioObserver, inverted microscope, Zeiss

The AxioObserver employs LEDs (Colibri, Zeiss) as an excitation source of fluorescence. Currently, 365 nm, 420 nm, 470 nm and 590 nm LEDs are installed. DefiniteFocus monitors and reliably compensates focus drifts with a closed loop system. The microscope equipped with an incubation chamber for temperature control.

Main Applications:

Long term bright field and fluorescence live cell imaging


Wide-Field Total Iinternal Reflection Fluorescence (TIRF) microscope

The TIRF microscope is built around an Olympus IX81 inverted microscope and equipped with a Hamamatsu EM-CCD camera allowing single-molecule detection. ZDC (Z Drift Compensation) module monitors and reliably compensates focus drifts. As fluorescence activation and excitation sources the following CW- laser lines are used: 405 nm, 488 nm, 514 nm, 561 nm and 640 nm.

Main Applications:

* Single-molecule imaging
* Super resolution microscopy
* Time lapse imaging
