2. Confocal microscopy - Wikipedia

   en.wikipedia.org/wiki/Confocal_microscopy

   Fluorescence and confocal microscopes operating principle. Confocal microscopy, most frequently confocal laser scanning microscopy (CLSM) or laser scanning confocal microscopy (LSCM), is an optical imaging technique for increasing optical resolution and contrast of a micrograph by means of using a spatial pinhole to block out-of-focus light in image formation.

3. Zoom lens - Wikipedia

   en.wikipedia.org/wiki/Zoom_lens

   A zoom lens is a system of camera lens elements for which the focal length (and thus angle of view) can be varied, as opposed to a fixed-focal-length (FFL) lens . A true zoom lens or optical zoom lens is a type of parfocal lens , one that maintains focus when its focal length changes. [ 1 ]

4. Optical transfer function - Wikipedia

   en.wikipedia.org/wiki/Optical_transfer_function

   In both cases the numerical aperture of the objective is 1.49 and the refractive index of the medium 1.52. The wavelength of the emitted light is assumed to be 600 nm and, in case of the confocal microscope, that of the excitation light 500 nm with circular polarization. A section is cut to visualize the internal intensity distribution.

5. Full-spectrum photography - Wikipedia

   en.wikipedia.org/wiki/Full-spectrum_photography

   Full-spectrum photography is a subset of multispectral imaging, defined among photography enthusiasts as imaging with consumer cameras the full, broad spectrum of a film or camera sensor bandwidth. In practice, specialized broadband/full-spectrum film captures visible and near infrared light, commonly referred to as the " VNIR ".

6. Optical microscope - Wikipedia

   en.wikipedia.org/wiki/Optical_microscope

   The optical microscope, also referred to as a light microscope, is a type of microscope that commonly uses visible light and a system of lenses to generate magnified images of small objects. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century.

7. Point spread function - Wikipedia

   en.wikipedia.org/wiki/Point_spread_function

   By virtue of the linearity property of optical non-coherent imaging systems, i.e., . Image(Object 1 + Object 2) = Image(Object 1) + Image(Object 2). the image of an object in a microscope or telescope as a non-coherent imaging system can be computed by expressing the object-plane field as a weighted sum of 2D impulse functions, and then expressing the image plane field as a weighted sum of the ...

8. Condenser (optics) - Wikipedia

   en.wikipedia.org/wiki/Condenser_(optics)

   A condenser is an optical lens that renders a divergent light beam from a point light source into a parallel or converging beam to illuminate an object to be imaged. Condensers are an essential part of any imaging device, such as microscopes, enlargers, slide projectors, and telescopes.

9. List of standard zoom lenses - Wikipedia

   en.wikipedia.org/wiki/List_of_standard_zoom_lenses

   Sony 28-70mm F3.5-5.6, a standard zoom lens. This is a list of standard zoom lenses that are designed for mirrorless cameras — limit one per brand, focal length, aperture, and zoom mechanism combination.
