OBJECTIVE LENS OF MEDIUM POWERPURPOSE:To obtain a flat image and provide a high resolving power by using an optical system consisting of three combined lenses which satisfies the specific conditions with respect to the radii of curvature of the lenses, the thickness thereof, the interval ...
or two positive lenses, the fourth lens component is a negative meniscus lens with its convex surface positioned toward the object, and for which the number of lenses constituting the objective is small, the working distance is large, flatness of image is high and resolving power is also high...
The bias on the specimen is set near the mirror condition, and focusing by the objective lens was adjusted to obtain maximum contrast. The tilted bright lines represent magnetic bits recorded onto the hard disk before experimental viewing. The image in Figure 43b, showing the same area of the...
The coloration of glass was carried out under the irradiation of 473 nm laser with and without focusing. The 473 nm laser (MBL-N-473 nm-1 W) was focused by a 50× (NA = 0.55; WD = 8.2 mm) objective lens (EPLE-50). The resolution of the laser spot was about ...
Recently, a scatter-plate microscope32, which uses the scatterer as a tunable objective lens of a microscope and can detect objects through scattering layers, has been demonstrated, but the reconstruction procedure has not shown 3D imaging capability. Similarly, another incoherent imaging technique33 ...
A major objective in recording optical disc masters is to control the geometry of the pits used to record data on the disc. Poor pit geometry makes the separation of duplicate discs from the disc stampers difficult. Also, data transmission can be affected by pits having raised areas surrounding...
The recording laser lights in both the channels, which have passed through the light expander unit 44 are condensed by the objective lens 45 and subjects the photoresist 20 on the glass master 23 to the exposure. The exposure spots of both the channels are spaced apart by a minute distance ...
PROBLEM TO BE SOLVED: To make it possible to accurately correct the tilt of an objective lens with respect to an information recording medium without being made large in size and high in price.;SOLUTION: When the tilt of the objective le... 武田 浩 被引量: 0发表: 2003年 Optical informat...
(b) selectively effecting either a first type of recording by irradiating the medium with a light beam having a power sufficient to heat the medium close to the Curie point of the first magnetic layer, thereby orienting the direction of magnetization of the first magnetic layer in a direction ...
