Toxic sample hold by a scientist in a laboratory - radioactive - fluorescence in conical flask - erlenmeyer flask
Squash preparation of  onion root tip cells stained to reveal chromosomes,  Bright field illumination, light microscopy.  This image was taken with the X40 objective lens.  Depth of focus is extremely low at this magnification.  Smaller apertures give greater depth of focus, but image quality deteriorates and resolution is greatly reduced.  The aperture in this image was optimised for contrast and resolution. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
The scientist is meticulously working in a biosafety cabinet, wearing protective mask, gloves, and lab coat. Using a Bunsen burner, test tubes, and various lab equipment for experiments.

Squash preparation of stained onion root tip cells showing various stages of mitosis. Differential interference contrast optics on a Leica microscope, Image taken with the X40 objective lens.  Depth of focus is extremely shallow (just a few microns).  Differential interference contrast results in an optical slice horizontally through the specimen providing maximum possible resolution at this magnification and good contrast. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
