position before the lens is integrated into instrumentation, eliminating the need for future
adjustments. A variety of fixed-aperture options allow maximum flexibility of resolution,
throughput and depth of field, and each focal
length is offered in a range of f/number options. Seventeen aperture stop versions, from
f/1.4 to f/8 in 16-, 25- and 35-mm focal lengths,
are available. Customized f/number versions
also are offered.
The IsoPlane SCT-320, an imaging spectro-
graph from Princeton Instruments, eliminates
the aberrations present in traditional imaging
spectrographs. It produces clearer and sharper
images across the focal plane, enabling more
photons to end up in spectral peaks and in-
creasing the signal-to-noise ratio. The spectro-
graph reduces coma, preserving spectral
resolution at all wavelengths. There is no
astigmatism, allowing many more fibers in
a bundle to be resolved and eliminating
crosstalk in multichannel spectroscopy. The
mirror-based device combines high-quality
imaging with an f/4.6 aperture, a motorized
triple-grating turret and an ultrastable me-
chanical design. Applications include multi-
channel spectroscopy, microspectroscopy,
Raman scattering, fluorescence, photolumi-
nescence, laser-induced breakdown spec-
troscopy, Fourier-domain spectroscopy
and biomedical imaging.
