Aug 17, 2017 Koehler realised that for consistency in illumination, every single component of the microscope needs to be considered and correctly aligned in relation to each other. By making adjustments to the diaphragms and condensers, he overcame the main problems of overheating and light consistency even using an opera glass in place of a convex lens.
Light from a point on the left the light source filament in Fig.1 expands in all directions.If emitted at a distance from the lens equal to the lens focal length, it is organized to a collection of parallel rays upon exiting the lens.While only the direct, central ray and a large angle ray are illustrated, every ray in the collection angle of the lens behaves similarly.
K hler integration can be achieved by a single solid lens or by a pair of lens arrays to render an arbitrary intensity distribution of collimated light into a pill box intensity distribution. Figure 1 shows two symmetrical lenslet arrays separated by a dielectric material refractive index n 1 by a distance t that is equal to their focal length.
