उदाहरण वाक्य
- Others include explosion proof enclosures, venting, oil immersion, powder and sand filling, and hermetic sealing.
- All specimens, regardless of consistency, are permanently stained prior to microscopic examination with an oil immersion lens.
- An "'oil immersion objective "'is an objective lens specially designed to be used in this way.
- This discovery remained controversial until the development of the oil immersion lens in 1884 and of superior staining methods in 1890 1891.
- Use of an oil immersion lens with the incorrect immersion oil, or without immersion oil altogether, will suffer from spherical aberration.
- Until the development of synthetic immersion oil in the 1940s, cedarwood oil was widely used for the oil immersion objective in light microscopy.
- With an optical microscope having a high numerical aperture and using oil immersion, the best possible resolution is 200 nm corresponding to a magnification of around 1200?
- Oil immersion can generally only be used on rigidly mounted specimens otherwise the surface tension of the oil can move the coverslip and so move the sample underneath.
- Dual dry / immersion condensers are basically oil immersion condensers that can nonetheless focus light with the same degree of precision even without oil between the top lens and the slide.
- Oil immersion objectives can have practical difficulties due to their shallow depth of field and extremely short working distance, which calls for the use of very thin ( 0.17mm ) cover slips, or, in an inverted microscope, thin glass-bottomed Petri dishes.
