    Abstract: The present invention provides systems and methods for quantifying, purifying and separating fullerenes, such as single wall carbon nanotubes (SWNTs). The purification/separation combination provides nearly 100% carbonaceous impurity-free SWNT content from a given impure sample and provides a desired chirality and diameter from a given non-separated sample. Nanometrological validation of the success of purification and separation uses a pyroelectric detector and Raman spectroscopy in a single system, thus providing a critical aspect for the nanomanufacturing environment. The purification/separation and nanometrological validations may be performed in a feedback loop to provide a satisfactorily refined sample and optimized purification/separation settings.

    Abstract: A tunable transmissive grating comprises a transmissive dispersive element, a reflective element, and an angle θ formed between the two elements. A first optical path is formed according to the angle θ, wherein light dispersing from the dispersive element is directed onto the reflective element and reflects therefrom. At least one element is rotatable about a rotational center to cause a second optical path and thereby tune the wavelength of the light reflecting from the reflective element. Both elements can be rotatable together around a common rotational center point according to certain embodiments, and/or each element can be independently rotated around a rotational axis associated only with that element. According to some embodiments, the relative angle θ formed between the elements is held constant; however, in other embodiments θ can vary.

    Abstract: A spectrometer is designed capable of effectively covering the full desired spectral range using an array of multiple diffraction gratings arranged in gradually differentiated angles to diffract certain sub-range of photon wavelengths to the target detectors without relying on mechanically changing gratings or use of any moving parts. The optically subdivided spectral analysis results are then electronically integrated to accurately yield the desired full range spectral measurement at a speed compatible to the limit of optical and digital analyzers' speed of the measuring system without manual adjustment and/or mechanical movement delays.

    Abstract: A spectroscope is provided with a point light source which emits a dispersed light having a plurality of wavelengths, a first optical system which collimates the dispersed light which is emitted from the point light source into an approximate parallel light flux, a dispersing element which disperses the approximate parallel light flux, and a second optical system for condensing the dispersed light flux near a focal plane. Aberrations for a plurality of wavelengths of an off-axial light flux are compensated in the second optical system. By doing this, it is possible to provide a spectroscope which has a high wavelength resolution.
