NettetUniform illumination has the additional advantage of creating higher contrast. One way to create such illumination is by using what is called a Koehler illumination system . To create a Koehler illumination setup, we need two adjustable diaphragms: one near the light source (also called condenser diaphragm or CD) and the other close to the ... NettetThe invention discloses a condenser lens of an LED (light emitting diode). The condenser lens is a rotary body in a shape of a circular truncated cone and is provided with an optical axis which is superposed with a rotary shaft of the rotary body. The condenser lens comprises a light source containing slot, a light emitting surface and a full reflecting …
Köhler illumination is a method of specimen illumination used for transmitted and reflected light (trans- and epi-illuminated) optical microscopy. Köhler illumination acts to generate an even illumination of the sample and ensures that an image of the illumination source (for example a halogen lamp filament) is not visible in the resulting image. Köhler illumination is the predominant technique for sample illumination in modern scientific light microscopy. It requires additional opti… NettetLeslie’s team also led the design and development of the Nike Wing, a groundbreaking unibody lens worn by Olympic track and field athletes …
