A design method for a thermal control film advantageously used in cosmic space, especially for a multilayer film, includes: setting at least two candidate materials for forming the multilayer film and the number of layers of the multilayer film; and designing a combination of the candidate material and a layer thickness by using a genetic algorithm stored in a computer-readable medium using an evaluation function, and recording the obtained results on a computer-readable medium. The evaluation function includes: &#x3b1;s=1&#x2212;Rs, wherein Rs represents a reflectance of solar energy in a wavelength range used for design, within a solar radiation wavelength range; and &#x2208;H: &#x2208;H=1&#x2212;R, wherein Rrepresents a reflectance of heat radiation energy in a wavelength range used for design, within a heat radiation wavelength range.

Method for designing sunlight-reflection and heat-radiation multilayer film

The present invention provides a small sized wide wave-range spectroscope with a simple structure which requires a short time to measure light for measurement over a wide wavelength spectrum. The small sized wide wave-range spectroscope has a collimator () for changing light for measurement (L) transmitted through a slit () into collimated light (L), a plurality of diffraction gratings () with different grating constants d supported rotatably around a rotational axis in parallel with the incident slit () and disposed side by side in the direction of the rotational axis in the optical path of the collimated light (L), and a diffracted-light focusing members () for focusing a plurality of diffracted light rays (Lto L) provided by the plurality of diffraction gratings () by which the collimated light (L) is diffracted, each of the diffracted-light focusing members () being provided in association with each of the plurality of diffraction gratings ().

Small sized wide wave-range spectroscope

A wireless measuring deviceis provided which includes a plurality of child unitsand a parent unitto receive data measured by these child unitsby wireless communication. Each of the child unitshas a controlling sectionthat can move to a standby state, a measuring section, a signal receiving sectionto receive a measurement instructing signal from the parent unit, and a signal transmitting sectionto transmit the measured data by wireless communication. The parent unithas a signal transmitting section to transmit the measurement instructing signal to each of the child unitsand a measured data receiving sectionto receive measured data to be transmitted from the signal transmitting section
