MEDIUM MAGNIFICATION OBJECT LENSPURPOSE:To obtain a lens for video disk application which is longer in its operating range and flatter in its image and better in its resolving power by composing an optical system with four groups of lenses which are given with specific conditions regarding its ...
A medium magnification objective for video disks comprising a first, second, third and fourth lens components in which the first lens component is a negative lens, the second lens component is a positive meniscus lens with its concave surface positioned toward the object, the third lens component...

In those cases, the optical set-up is built around a microscope and the spot size is mainly defined by the magnification of the objective lens. When this is not the case, e.g., in the case of nanoscale roughness, additional film layers are required in order to model the rough thin ...

a To maximize the bright-field microscope’s resolving power, an oil immersion lens (the one with highest magnification) must have a drop of oil placed at its tip. This forms a continuous medium to transmit a beam of light from the condenser to the objective lens and effectively increase th...
(including 90D and SuperPupil XL lens). The cornea has a high refractive power; thus, it is possible to see only the anterior one-third of the eye using a slit-lamp biomicroscope.[1]Special lenses, thus, need to be placed in front of the slit-lamp objective lens to...
