The white color fluorescent tube W is arranged at a position closest to the end surface in a longitudinal direction of the light guide plate. Luminances of these fluorescent tubes W, R, G, B can be adjusted independently by control voltages supplied from external devices. Lights emitted from a plurality of light sources enter into the light guide plate, and then the lights are emitted from the light guide plate in a predetermined direction. Since the backlight unit itself has a color adjusting function, the reduction of the luminance and the change of the color balance due to degradation of the fluorescent tubes can be corrected.

    Abstract: An illuminating device of a projection-microlithographic device includes a light source, an objective, and a device which produces a particular image field configuration. The device has fields which, in the direction of scanning movement, are separated at least in parts by a free zone, and are located in a peripheral region of the circular image field of a downstream projection objective in a manner at least approximating rotation symmetry. The integral of the quantity of light passing through the fields in the scanning direction are constant over the entire extent of the image field configuration in the direction at right angles to the scanning direction. Such an image field configuration replaces a conventional rectangular scanner slot formation whose width in the scanning direction corresponds to the forementioned integral of the image field configuration. The design of the image field configuration permits an approximately rotationally symmetric illumination of the projection objective.

When the spring members (3a-3c) return the fine moving stage (1) to a statically balanced state, a rotation moment is generated to score or damage the stage. The spring constants of the three spring members (3a-3c) are set based on the relative positions of the spring members (3a-3c) to the barycenter (G), thereby preventing generation of the rotation moment.

  • Publication number: 20010052973
    Abstract: An apparatus for measuring polarization dependent loss is disclosed featuring several fiber optic couplers combined in tandem and oriented such that the PDL noise of the measurement system is reduced to a negligible level. By matching the PDLs of the couplers and vectorally subtracting opposite phases of polarization, the PDL of the measurement system is virtually eliminated. Thus, the PDL noise floor is lowered to near zero and the PDL of the optical device-under-test (DUT) can be accurately measured. The system is relatively inexpensive to implement and offers needed versatility because it measures the PDL of optical devices that operate in a reflection mode or in a forward transmission mode. Thus, it provides one PDL measurement solution for both types of devices.

  • Publication number: 20010052979
    Abstract: An apparatus incorporated within a spectroscopic imaging system, typically a microscope, but also applicable to other image gathering platforms, namely fiberscopes, macrolens imaging systems and telescopes employing a polarizing beam splitting element is disclosed. The apparatus allows simultaneous spectroscopic (i.e. chemical) imaging and rapid acquisition spectroscopy to be performed without the need for moving mechanical parts or time sequenced sampling and without introducing significant optical signal loss or degradation to the spectroscopic imaging capability. In addition, the apparatus affords a more compact design, an improved angular field of view and an improved overall ruggedness of optical design at a lower manufacturing and maintenance cost compared to previous devices.

  • Publication number: 20010052980
    Abstract: A compact and high-performance spectroscope capable of providing a resolution of 0.1 pm or less as in the case of a large-sized spectroscope with an increased focal length and suitable for measuring the spectral distribution of an excimer laser beam. A collimating optical system collimates light under measurement passing through an entrance slit. The collimated light is incident on a diffraction grating and diffracted at angles differing depending on wavelengths. An imaging optical system focuses a beam of light diffracted by the diffraction grating. An exit slit or a light distribution detector is placed in a focal plane of the imaging optical system. A beam diameter-expanding optical system is placed at least between the collimating optical system and the diffraction grating to expand the diameter of the beam of light collimated by the collimating optical system at least in the direction of dispersion of the diffraction grating.

  • Publication number: 20010052982
    Abstract: Amplified spontaneous emission light, which is low coherence light radiated out from an optical fiber doped with a light emitting material when excitation energy is applied to the optical fiber, is divided into signal light and reference light. A frequency of the reference light is shifted to a frequency slightly different from the frequency of the signal light. A tomographic image of a measuring site is acquired from an intensity of interference light formed by the signal light reflected from the measuring site and the reference light.

    Abstract: A device for quantitative assessment of the aligned position of two machine parts, workpieces or the like is used especially for purposes of axis alignment or spindle alignment. A light beam is incident on an optoelectronic sensor which can be read out two-dimensionally and the impact point there is determined by the sensor. Part of the light beam is preferably reflected by the sensor directly onto a second optoelectronic sensor. The impact point of the reflected light beam there is determined in a feasible manner by the second sensor. The orientation of at least the first sensor relative to the location of the light beam is determined from the signals of the two sensors.

  • Publication number: 20010052987
    Abstract: A film thickness measuring method and apparatus capable of measuring a film thickness with high accuracy even if the spectral reflection intensity is not sufficiently high to measure an accurate film thickness and gives a poor S/N ratio. A spectral reflectance ratio S(&lgr;) at a spot where the film under measurement is present and a spectral reflectance ratio R(&lgr;) at a spot where the film under measurement is not present are measured to determine a spectral reflectance ratio Rmeas(&lgr;)=S(&lgr;)/R(&lgr;). A theoretical value Rcalc(&lgr;) of spectral reflectance ratio at an assumed film thickness d is determined, and an evaluation value Ed is determined from the total sum of differences between the value of Rmeas(&lgr;) and the value of Rcalc(&lgr;). The film thickness d is changed in steps of &Dgr;d in a measuring retrieval range of from d1 to d2 to determine an evaluation value Ed at each film thickness, thereby obtaining an evaluation function E(d).
