Monochromators using high efficiency diffraction
gratings are found in many applications including the spectrophotometer
and spectroradiometer. Macam has designed and manufactured a range
of concave grating monochromators to meet the demands of high precision
Our monochromators are available in two focal lengths:
Each has a range of concave holographic
diffraction gratings covering the ultra-violet, visible and near
infrared spectra. Special models have interchangeable gratings for
extended spectral range.
The MCG990 double monochromator model
ensures low stray light levels for particular use in ultraviolet
spectroradiometry. All monochromators have multiposition entrance
and exit slits for a choice of output bandwidths. Grating motor
control and drive electronics with PC software allow automation
for routine spectral measurements.
