“…Prism spectrometers have a higher transmission efficiency over a wide spectral range as compared with diffraction gratings [23], so they are more suitable for this application. The spectrometer is an aplanatic design [24], with a dispersion element that consists of a spherical wedge prism and a spherical concave mirror. The design was optimized using optical design software (Optics Software for Layout and Optimization, Lambda Research Corporation) to minimize distortion.…”

Many cellular signaling processes are initiated by dimerization or oligomerization of membrane proteins. However, since the spatial scale of these interactions is below the diffraction limit of the light microscope, the dynamics of these interactions have been difficult to study on living cells. We have developed a novel high-speed hyperspectral microscope (HSM) to perform single particle tracking of up to 8 spectrally distinct species of quantum dots (QDs) at 27 frames per second. The distinct emission spectra of the QDs allows localization with ∼10 nm precision even when the probes are clustered at spatial scales below the diffraction limit. The capabilities of the HSM are demonstrated here by application of multi-color single particle tracking to observe membrane protein behavior, including: 1) dynamic formation and dissociation of Epidermal Growth Factor Receptor dimers; 2) resolving antigen induced aggregation of the high affinity IgE receptor, FcεR1; 3) four color QD tracking while simultaneously visualizing GFP-actin; and 4) high-density tracking for fast diffusion mapping.

“…In addition, they do not suffer from order effects and stray light. The spectrometer proposed here basically follows the optical design of Warren et al [32], which is based on aplanatic conditions and was derived from earlier designs of Wilson [33]. The advantage of this design is an almost coma and aberration free image together with a flat image plane suitable for modern FPA detectors.…”

“…We found, that the dispersion of BaF 2 optimally fulfills our design specifications when compared with CaF 2 . In addition, BaF 2 ensures a fast F-number of the spectrometer due to its low index of refraction [32].…”

“…A preliminary solution for the optical design of the spectrometer was found following the recipe of Warren et al [32] that was consequently optimized by performing non-sequential ray tracing computations with both the software packages SYNOPSIS [34] and Zemax [35]. The optimized parameters for the optical elements of the spectrometer core are summarized in Table 3.…”

a b s t r a c tSeveral attempts have been made to extend time-resolved mid infrared spectroscopy to higher time resolution. Such methods are either limited to specific samples that are cyclic and therefore allow the reaction under investigation to be repeated multiple times in the same manner, or they lack spectral resolution or sufficient signal-to noise ratio. Here, we report on a single-shot spectrometer concept which overcomes the aforementioned limitations utilizing fast linear detector arrays and highly brilliant infrared synchrotron radiation. The spectrometer may find applications, beside others, for the investigation of irreversible cascades of structural alterations in proteins.

“…When the instrument is being assembled or adjusted, heating the NaCl lens above the dew point and providing a local dry nitrogen purge are sufficient to prevent damage from ambient humidity. Our previous prism instruments 10 have a combined 20-year history employing NaCl prisms with only one damaged prism caused by a corroded vacuum fitting.…”

The Dyson spectrometer form has the potential to deliver good imaging performance, high throughput, and low distortion in a compact configuration suitable for cryogenic infrared applications. The three main requirements for a practical implementation-availability of the required concave diffraction grating, availability of the Dyson lens material, and clearance for slit and focal plane packaging-are now within the state of the art, opening the Dyson form to serious consideration. Several high-performance Dyson designs for the long-wavelength infrared are presented. © 2008Society of Photo-Optical Instrumentation Engineers.
