| Zusammenfassung |
| A breadboard demonstrator of a novel UV/VIS grating spectrometer has been
developed based upon a concentric arrangement of a spherical meniscus lens,
concave spherical mirror and curved diffraction grating suitable for a range
of atmospheric remote sensing applications from the ground or space. The
spectrometer is compact and provides high optical efficiency and performance
benefits over traditional instruments. The concentric design is capable of
handling high relative apertures, owing to spherical aberration and comma
being near zero at all surfaces. The design also provides correction for
transverse chromatic aberration and distortion, in addition to correcting
for the distortion called "smile", the curvature of the slit image formed at
each wavelength. These properties render this design capable of superior
spectral and spatial performance with size and weight budgets significantly
lower than standard configurations. This form of spectrometer design offers
the potential for exceptionally compact instrument for differential optical
absorption spectroscopy (DOAS) applications from LEO, GEO, HAP or
ground-based platforms. The breadboard demonstrator has been shown to offer
high throughput and a stable Gaussian line shape with a spectral range from
300 to 450 nm at 0.5 nm resolution, suitable for a number of typical DOAS
applications. |
