Kohler illumination works with all methods of microscopy including dic, phase contrast, polarization, brightfield, darkfield and all epi-illuminations. Sometimes referred to as double diaphragm illumination, it uses both a field and an aperture diaphragm to focus the illumination and provides an evenly illuminated viewing field, a bright.

Microscope - microscope - the illumination system: the illumination system of the standard optical microscope is designed to transmit light through a translucent object for viewing. In a modern microscope it consists of a light source, such as an electric lamp or a light-emitting diode, and a lens system forming the condenser. The condenser is placed below the stage and concentrates the light.
For high resolution samples, electronic imaging quantitative microscopy or critical photomicrography, match the na of the condenser to the highest na of the objective.
But when doing remote microscopy, parfocality between different magnifications becomes a critical component for smooth observation. With the perfect parfocality setting, you won’t need to readjust the focus when switching magnifications.
Second harmonic generation (shg) is a second‐order non‐linear optical process produced in birefringent crystals or in biological tissues with non‐centrosymmetric structure such as collagen or microtubules structures. Shg signal originates from two excitation photons which interact with the material and are “reconverted” to form a new emitted photon with half of wavelength.
