Both light and electron microscopy techniques that omit the unscattered beam from the picture are referred to as dark-field microscopy (also known as dark-ground microscopy). As a consequence, there is typically no light in the area surrounding the specimen (i.e., where there is no specimen to scatter the beam).
To guide a cone of light away from the objective lens in optical microscopes, a darkfield condenser lens must be used. Oil immersion is used, and the objective lens's numerical aperture (NA) must be less than 1.0 to achieve the highest amount of dispersed light collection potential.
Only objective lenses with an adjustable diaphragm, which lowers the NA, can be used with greater NA objective lenses.
The Global Dark field microscope market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
For absorption and transillumination imaging modes, a number of dark-field condensers have been developed and offered commercially.
The use of a standard microscope for dark-field imaging is possible with a special dark-field condenser. Some unique objectives with built-in dark-field illumination characteristics have been created and made available for sale for reflectance imaging mode.
For dark-field imaging, the suggested device is capable of both reflectance and transmission modes of operation, a dark-field transmission lens.
Lens L1 (Thorlabs AC508-150-A-ML, focal length: 150 mm) images the structured light pattern from the digital micromirror device (DMD) projector (DLP® DiscoveryTM 4100 Development Platform) first to an intermediated image, which is then collimated by lens L2 (Doublet, focal length: 500 mm).
In order to produce dark-field illumination, the objective O1 (NA=0.75) is used with a ring aperture to block the light's central portion while allowing the light's periphery to pass through and focus on the sample plane.
In this lighting arrangement, a wide angle of the DMD array is projected onto the object. As a result, the item can be covered with a collection of phase-shifted fringe patterns.
The objective O2 gathers the light that is scattered from the sample and obstructs the light from the direct illumination due to its smaller aperture (NA=0.4) than the objective O1.
Lens L3 (Thorlabs AC254-150-A-ML, focal length=150 mm) creates a darkfield picture on the detector plane (IDS, UI-3080SE-C-HQ, 2456 x 2054 pixels resolution, 3.45 m pixel pitch).
