Microscope overview
The ZEISS Axio Imager with Apotome 2 is a fully automated upright microscope capable of magnifications from 2.5x to 160x and equipped with two cameras: On the left port a 5MPx CMOS color camera (Axiocam 105 RGB, for brightfield/DIC) and on the top port a high sensitivity 4 Mpx monochrome sCMOS camera (Hamamatsu Flash 4.0v2, for fluorescence). The system has a Colibri 7 excitation light source with 5 LEDs (see table below). The system’s stage, which can accommodate 8 slides simultaneously, is motorized in XYZ, capable of z-stacks, multiple positions or tile and stitching acquisition (thereby allowing acquisition of large fields of view with several hundred megapixels). The Imager is also equipped with ApoTome.2, which allows optical sectioning of fluorescent samples using structured illumination. A grid pattern is placed on the illumination path and is projected and shifted sideways; 3 (or more) images are acquired and between each image the grid is moved 1/3 of its cycle. This movement generates images where only the in-focus light is modulated by the grid pattern while out-of-focus light is largely unaffected by the grid. By subtracting pairs of these images, the system removes out-of-focus light and the grid pattern, thus creating an optical section of the sample.
System components
LEDs
| Line | Wavelength | Power (with 10x) |
|---|---|---|
| UV | 385 nm | ~ 160* mW |
| B | 475 nm | ~ 120 mW |
| G | 555 nm | ~ 20 mW |
| Y | 590 nm | ~ 14 mW |
| R | 630 nm | ~ 44 mW |
* don't exceed 5% power as this line bleaches samples quickly.
