New high-brightness monochromator improves photon delivery for analytical and experimental success
Today intense light - of any wavelength - often originates small. Today's surface mount LED sources are on the scale of couple hundred microns. High harmonic generation laser capillaries are in this size range too and for UV/Vis wavelengths and laser plasma sources focus even smaller. Material scientists and chemists must often work with tiny sample volumes / quantities.
- (1888PressRelease) November 30, 2016 - The McPherson Model 207 is the best spectrometer when you need high-brightness over a broad spectral range. It serves from the deep UV, through visible into the long-wave infrared. It is an ideal instrument for use in tunable light source systems for illumination, imaging and spectroscopy.
The new Model 207A is a 670mm focal length optically fast f/4.7 monochromator. It is now available with off-axis parabolic optics. The off-axis parabolic (OAP) mirrors provide both low f/number and stigmatic monochromator performance. Stigmatic monochromators are somewhat exotic because so many other monochromator designs use spherical optics and exhibit astigmatism to some degree. The Model 207A with OAP optics provides coincident sagittal and tangential foci and perfect collimation and focusing. These highly polished OAP mirrors with smooth surfaces are especially suitable for work in the deep UV and vacuum region. The Model 207A preserves high brightness with no chromatic aberrations.
Other features include Snap-In™ diffraction gratings, precise and durable slits for free-space or fiber optic coupling, and an accessible oversize focal plane for your CCD of choice. Researchers that need versatile high brightness as a tunable light source for diagnostic or analytical spectroscopy in the life sciences use the Model 207A. Consult McPherson and we will help make sure the spectrometer is ready for implementation in your specific application.
