Microscopy Part 6 - Dark Field Microscopy Basics | Principle and Working | In Hindi

#Baayo Microscopy Part 6 - Dark Field Microscopy Basics | Principle and working in Hindi In this video tutorial we talk about Darkfield Microscopy principle, uses and working in hindi The dark field microscopy utilize detection of the signals away from the optical axis - i.e. scattered signals. light path through a dark-field microscope is : 1. Light enters the microscope for illumination of the sample. 2. A specially sized disc, the patch stop (see figure), blocks some light from the light source, leaving an outer ring of illumination. A wide phase annulus can also be reasonably substituted at low magnification. 3. The condenser lens focuses the light towards the sample. 4. The light enters the sample. Most is directly transmitted, while some is scattered from the sample. 5. The scattered light enters the objective lens, while the directly transmitted light simply misses the lens and is not collected due to a direct-illumination block . 6. Only the scattered light goes on to produce the image, while the directly transmitted light is omitted.
