  2. Oil immersion - Wikipedia

    en.wikipedia.org/wiki/Oil_immersion

    Immersion oils are transparent oils that have specific optical and viscosity characteristics necessary for use in microscopy. Typical oils used have an index of refraction of around 1.515. [1] An oil immersion objective is an objective lens specially designed to be used in this way. Many condensers also give optimal resolution when the ...

  3. Raman microscope - Wikipedia

    en.wikipedia.org/wiki/Raman_microscope

    Raman microscope. The Raman microscope is a laser-based microscopic device used to perform Raman spectroscopy. [1] The term MOLE (molecular optics laser examiner) is used to refer to the Raman-based microprobe. [1] The technique used is named after C. V. Raman, who discovered the scattering properties in liquids.

    Immersion oils are transparent oils that have specific optical and viscosity characteristics necessary for use in microscopy. Typical oils used have an index of refraction around 1.515. [ 2 ] An oil immersion objective is an objective lens specially designed to be used in this way.

  5. Optical microscope - Wikipedia

    en.wikipedia.org/wiki/Optical_microscope

    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.

  6. Objective (optics) - Wikipedia

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

    Two Leica oil immersion microscope objective lenses; left 100×, right 40×. The objective lens of a microscope is the one at the bottom near the sample. At its simplest, it is a very high-powered magnifying glass, with very short focal length. This is brought very close to the specimen being examined so that the light from the specimen comes ...

  7. Total internal reflection fluorescence microscope - Wikipedia

    en.wikipedia.org/wiki/Total_internal_reflection...

    A total internal reflection fluorescence microscope (TIRFM) is a type of microscope with which a thin region of a specimen, usually less than 200 nanometers can be observed. TIRFM is an imaging modality which uses the excitation of fluorescent cells in a thin optical specimen section that is supported on a glass slide.

  8. Condenser (optics) - Wikipedia

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

    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 slide/coverslip and the lens of the condenser. An oil immersion condenser may typically have NA of up ...
