1/8 Monochromator/Spectrograph

CM/CMSP 110

Features:


·Compact size (5.25 x 3.25 x 3.25 inches) & Connection to computer via RS 232

·Scans in both directions. Programmable in Angstrom, nanometers, microns, wavenumbers, or eV.

·Dual double-grating turrets with automatic grating change allowing for broad spectral range coverage and broad spectral range coverage

·Suitable for fluorescence, radiometry, process control, colorimetry, tunable filtering, Raman spectroscopy, among others ; Able to change slits on the fly

·May be configured as a spectrograph or a monochromator (can also be factory configured for right angle or straight through beam path)


 

Single piece base construction, direct grating drive, and anti-backlash gearing ensure the unit is rugged and stable enough for demanding applications. Loaded with SP Optics and able to hold two high quality gratings, the CM110 is optiomal for spectrometry in the UV-IR spectra. 

 


CM/CMSP 112

Features: 


·  Compact Size(5.25 x 6.25 x 3.25 inches) & Connection to computer via RS 232

·  Scans in both directions. Programmable in Angstrom, nanometers, microns, wavenumbers, or eV.

· Dual double-grating turrets with automatic grating change allows for broad spectral range coverage.

· Modes to minimize image distortion and pulse spread, with sub-picosecond residual broadening of regular monochromators & increased dispersion and low stray light for Raman fluorescence studies.

·   May be configured as a spectrograph or a monochromator(can also be factory configured for right angle or straight through beam path)



The CM112 are two single monochromators in series. The exit slit of the first monochromator is the entrance slit of the second. The two monochromators act as a double filter with the rejection of stray light being almost the square of the single monochromator value. 

As an additive instrument, the first grating spreads the spectrum over an angular range while the second grating then doubles this dispersion, achieving twice the resolution of a single 1/8m monochromator.

As a subtractive instrument, the first monochromator selects a bandpass wihle the second monochromator then removes the temporal and angular aberrations introduced by the angular spectral dispersion in the first monochromator. 

The CM112 supercedes ordinary monochromators with its second substractive monochromator which can recombine multiple wavelenghts in the bandpass and instead of creating multiple, overlapping images, it creates a clear image. Also, its subtractive dispersion mode can also utilize its second monochromator to equalize the optical path lengths such that broadening is reduced to a minimum.

Monochromators act as tunable bandpass filters for light. They are the critical component for many spectral applications since they can be used to create tunable light sources and also to take high precision spectral measurements. The Digikröm line of monochromators, available in 1/8, 1/4 and 1/2 meter focal lengths, use electronics that are 'designed-in', rather than appended via accessories or other add-ons after the instrument has been manufactured. The Direct Digital Drive is simple and reliable; a microprocessor-controlled stepper motor, moving in wavelength increments as small as .01nm per step, is linked directly to the grating mount by a worm and worm wheel arrangement. This results in improved accuracy, automatic grating changes and exceptional ruggedness.



Application

SP monochromators can be applied to various applications: includes semiconductor, biomedical, manufacturing, petrochemicals, pulp/paper, clinical labs, QC labs, research & development, pharmaceutical, environmental control, polymers, mining/metals.

We offers a full line of monochromators.
