This is done by turning the knurled knob on the condensers illustrated in Figures 2-6. There is a small yellow arrow or index mark located on this knob that indicates the relative size of the aperture when compared to the linear gradation on the condenser housing.

20 Δεκ 2023 · The condenser is crucial to microscopy, shaping image quality and precision. Its structure, resembling a cylinder or prism, is strengthened by adjustment mechanisms. It forms the basis for fine-tuning optics. The complex lens system guides and focuses light, enhancing specimen illumination.
1 Ιουν 2019 · The condenser uses a high magnification lens to bring the rays of light into a fine point. The advantage of having a condenser is that the light will be sharper and it makes the most of the available light. The most common type of condenser is called an Abbe condenser.
The chapter explores the different types of condenser. The principal function of the eyepiece is to deliver parallel or near-parallel rays of light within the aperture of the eye. All eyepieces use the Keplerian method to deliver parallel rays of light to the eyes.
23 Μαΐ 2024 · Learn to optimize illumination in transmitted light microscopy by adjusting condenser light cone & aperture diaphragm. Know condenser types & capabilities.
Condenser -- This focuses the light on the slide and field of view. Diaphragm Lever -- This lever adjusts the condenser. You may need to use this when you change from one objective to another as the field of view shrinks.
Different brands and different models of microscopes position the key parts differently. When you first sit in front of a microscope, you should always take a second to find the key parts, especially the focus knobs, the condenser adjustment knob (if present), and the stage control knobs.
