Precision and Unlimited Versatility
The SpectraPro series of monochromator's and spectrographs are recognized as industry standards for rugged, high-performance operation and versatility. Each features an automated, multiple-grating turret for extended spectral coverage. Four standard focal lengths and a host of unique, customized features make SpectraPro spectrometers ideal for environmental, industrial, educational, and research applications. Through innovative engineering, these monochromator's and spectrographs can be incorporated into completely integrated spectroscopy systems customized to suit your specific application.

Higher Throughput
All SpectraPro monochromator's and spectrographs have high-aperture optics, and feature corrected and computer-optimized optics to reduce astigmatism. The SpectraPro models 300i, 500i, and 750 can be equipped with optional 68 x 84-mms to ensure that the full aperture of the spectrometer is maintained even at longer wavelengths. Other spectrometers typically suffer as much as a 30% loss in aperture at the longer wavelengths. All SpectraPro monochromator's and spectrographs also feature enhanced UV-to-VIS reflective coatings with 90% or better average reflectance. Specialized gold and silver reflective coatings for IR and NIR wavelengths are available as options.

No-Compromise Resolution
In high-aperture imaging spectrographs, the off-axis aberrations can compromise system performance. The best focal plane for spectral resolution is not the same as the best focal plane for spatial resolution of multiple fiber inputs. Only SpectraPro offers interchangeable focal-plane adapters optimized for your particular needs. Anything less is a compromise in performance.

Positrack Interchange
The advantage of having a multiple-grating turret is to be able to quickly changes. The wavelength of the spectrometer from to interchange should be maintained to the same precision as expected on a single.
