High dry lens magnification
Web12 de jul. de 2024 · This is due to the fact that most lenses would not be able to collect 180° of light from the specimen and the widest angle is approximately 144°. The sine of 144° is 0.95 and as air has a refractive index of 1.0, the theoretical maximum NA is close to 0.95. A high magnification objective lens with low NA will consequently have low resolution. Web5 de ago. de 2024 · The high-powered objective lens (also called “high dry” lens) is ideal for observing fine details within a specimen sample. The total magnification of a high-power objective lens combined with a 10x eyepiece is equal to 400x magnification, giving you a very detailed picture of the specimen in your slide.

WebA wet mount must be very secure to use oil. Oil immersion lenses are used only with oil, and oil can't be used with dry lenses, such as your 400x lens. Lenses of high magnification must be brought very close to the specimen to focus and the focal plane is very shallow, so focusing can be difficult. WebFor lenses of equal magnification, image brightness in epi-illumination systems is proportional to the fourth power of the numerical aperture. Calculations show that in comparing an ordinary high-dry lens of 0.65 NA with the 40X immersion lens of 1.30 NA, a 16-fold increase in brightness is obtained. Better High-Dry Images
