Abstract: A spectroscope is equipped with a temperature compensation mechanism that can reliably reduce a drift of a spectral image in the wavelength dispersion direction caused by a change in the environmental temperature irrespective of the form of the spectroscope. The spectroscope is provided with a first support member 17 that integrally supports an incidence member 11, a collective optical system 13 and a detection element 15, a second support member 21, made of a material different from the first support member, that supports a wavelength dispersion element 14, and a transmission member 24, 25 that transmits a contraction/expansion amount of the first support member to the second support member when environmental temperature changes. The second support member includes a deformation member 28 that elastically deforms, when environmental temperature changes, in accordance with a difference between its own contraction/expansion amount and the contraction/expansion amount of the first support member and a rotation member 26 that rotates minutely in accordance with elastic deformation of the deformation member. The said wavelength dispersion element is mounted on the rotation member in such a way that its wavelength dispersion direction is oriented perpendicular to the axial direction of the rotation member.

Abstract: A cooling fan for air-cooling a lamp housing is installed near to the lamp housing in which the lamp is accommodated. This cooling fan is adapted to suck out heated air surrounding the lamp housing directly to the outside of an apparatus. A time taken by the temperature of the lamp housing, which rises due to heat generated by the lamp, to reach a stable temperature is preliminarily set in a fan control portion. The fan control portion controls the cooling fan in such a way as to stop until this time elapses. Alternatively, the fan control portion initially operates the cooling fan at a rotating speed that is lower than a normal operation rotating speed, and thereafter causes the fan to start rotating at the normal operation rotating speed.

Abstract: A spectroscopy system is provided which operates in the vacuum ultraviolet spectrum. More particularly, a system utilizing reflectometry techniques in the vacuum ultraviolet spectrum is provided for use in metrology applications. To ensure accurate and repeatable measurement, the environment of the optical path is controlled to limit absorption effects of gases that may be present in the optical path. To account for absorption effects that may still occur, the length of the optical path is minimized. To further account for absorption effects, the reflectance data may be referenced to a relative standard. Referencing is particularly advantageous in the VUV reflectometer due to the low available photon flux and the sensitivity of recorded data to the composition of the gaseous medium contained with the optical path. Thus, errors that may be introduced by changes in the controlled environment may be reduced. In one exemplary embodiment, the VUV reflectometer may utilize a technique in which a beam splitter is utilized to create a sample beam and a reference beam to form the two arms of a near balanced Mach Zehnder interferometer. In another exemplary embodiment, the reference channel may be comprised of a Michelson interferometer.

Abstract: The invention concerns improvements in spectrophotometry. Aspects of the invention may be used independently or together to increase the sensitivity of spectrophotometry. One aspect of the invention is a spectrophotometer detection circuit. In this aspect of the invention, currents attributable to reference and sample beams are cancelled in the current mode. The detection circuit produces a first voltage proportional to the difference in currents and a second voltage proportional to one of the reference or sample beams. Both voltages are available to allow simultaneous measurement and analysis. Another aspect of the invention concerns thermal stability. According to the invention, thermal conductivity is established among the housing and optical system components to promote equilibrium. Another preferred embodiment has a unitary solid metal housing with a hollowed portion defined to mount and place optical system components. Recognition and identification of important noise sources in spectrophotometers forms an aspect of the invention contributing to the features and combinations of features in preferred embodiments. Many noise sources would not normally be considered in conventional spectrophotometry because the magnitude of particular noise sources dominates device performance.

Abstract: A wavelength division multiplexer/demultiplexer (WDM) for use in an optical network and in an optical performance monitor that minimizes increases in insertion losses over temperature variations has a structure for holding at least one optical component. A diffraction grating assembly having a substrate is held in relation to the at least one optical component by the structure. A lens assembly having a focal length is held in relation to the at least one optical component. The coefficient of thermal expansion of the lens assembly and structure are approximately equal. The grating assembly has an angular dispersion that changes with temperature and the product of the focal length and angular dispersion remains constant over temperature. The WDM further comprises a prism having a change in index of refraction with temperature that is approximately equal to a negative of a coefficient of thermal expansion of the substrate.

Abstract: The method and system operate to maintain a widely tunable laser (WTL) at a selected transmission wavelength. To lock the WTL to an ITU grid line, a portion of the output beam from the WTL is routed through the etalon to split the beam into a transmission line for detection by an etalon fringe detector. Another portion of the beam is routed directly to a laser wavelength detector to determine the power of the beam. A wavelength-locking controller compares signals from the two detectors and adjusts the temperature of the etalon to align the wavelength of one of the transmission lines of the etalon with the wavelength of the output beam, then controls the WTL in a feedback loop to lock the laser to the etalon line. The wavelength-locking controller thereafter monitors the temperature of the etalon and keeps the temperature constant to prevent any wavelength drift attributable to the etalon.

Abstract: This portable light source apparatus accommodates a deuterium lamp in a lamp box and, at the same time, in a housing in order for the influence of temperature changes in the outside air to become very small. Namely, the deuterium lamp, which is susceptible to changes in temperature, is enveloped not only by the lamp box but also by the housing, thereby being accommodated in a double shield structure. Further, it has been known that ozone is generated when ultraviolet rays are emitted in the air. Therefore, a light guide tube for extending a light exit opening of the lamp box is provided, so that cooling winds do not traverse the ultraviolet rays. As a result, ozone is restrained from occurring in the part where the ultraviolet rays occur within the housing, whereby the emitted light is appropriately kept from fluctuating due to the occurrence of ozone.
