Lens or camera fungus is the popular name for the infestation of optical devices such as lenses, low pass filter (OLPF) or the camera sensor, by fungal threads ().By germination of fungal spores and further spore formation, the infestation can spread beyond the initial fungal network.
Oil immersion objective lenses look superficially identical to non-oil immersion lenses. In light microscopy, oil immersion is a technique used to increase the resolving power of a microscope. This is achieved by immersing both the objective lens and the specimen in a transparent oil of high refractive index, thereby increasing the numerical ...
These lenses are often color coded for easier use. The least powerful lens is called the scanning objective lens, and is typically a 4× objective. The second lens is referred to as the small objective lens and is typically a 10× lens. The most powerful lens out of the three is referred to as the large objective lens and is typically 40–100×.
This kit is designed to clean pretty much anything you might put over your eyes — prescription eyewear, blue-light glasses, sunnies, virtual reality gear, even cameras and devices.
The maximum NA is limited by the refractive index of the medium between the lens and the sample. As with objective lenses, a condenser lens with a maximum numerical aperture of greater than 0.95 is designed to be used under oil immersion (or, more rarely, under water immersion), with a layer of immersion oil placed in contact with both the ...
In light microscopy, a water immersion objective is a specially designed objective lens used to increase the resolution of the microscope. This is achieved by immersing both the lens and the specimen in water which has a higher refractive index than air, thereby increasing the numerical aperture of the objective lens.
Different kinds of camera lenses, including wide angle, telephoto and speciality. A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses (compound lens) used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.
Objective stop dispersion staining takes advantage of the fact that all light unaltered by the presence of particles in the field of view is focused at the back focal plane of the objective. If the substage condenser iris is closed down then all of the direct light is focused into a small image of the opening in the substage condenser iris at ...
