| CM112 Compact 1/8 Meter Monochromator | |
| | - Compact size - Only 5-1/4"x6-1/4"x3-1/4"
- Connects to any computer via RS232.
- Scans in both directions. Programmable in angstroms, nanometers, microns, wavenumbers, or eV.
- Dual double-grating turrets with automatic grating change allows for broad spectral range coverage.
- Subtractive dispersion mode minimizes image distortion and pulse spread, with sub-picosecond residual broadening versus nanosecond pulse broadening of regular monochromators.
- Additive mode gives increased dispersion and low stray light for Raman and fluorescence studies.
- May be configured as a monochromator or a spectrograph.
- Monochromator may be factory configured for right angle or straight through beam path.
The Digikröm CM112: Much More than a Monochromator The CM112 is 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. The CM112 may be factory configured as an additive or subtractive dispersion double monochromator. As an additive instrument, the first grating spreads the spectrum over an angular range; the second grating then doubles this dispersion. The result is twice the resolution of a single 1/8 meter monochromator. As a subtractive instrument, the first monochromator selects a bandpass, the second monochromator then removes the temporal and angular aberrations introduced by the angular spectral dispersion in the first monochromator. The CM112 offers a solution to practical problems in monochromatic imaging. Selecting a monochromatic image with an ordinary monochromator fails because multiple wavelengths in the bandpass create multiple, overlapping images. In the CM112, the second subtractive monochromator recombines these multiple images, creating a clear image. Finally, the CM112 is a unique solution to practical problems in the spectroscopy of pulsed sources. An ordinary monochromator has a spread in the internal optical path lengths that will introduce a 25 to 100 picosecond broadening in light pulses that are passed through the monochromator. In the subtractive dispersion CM112, the second monochromator equalizes the optical path lengths so that broadening is reduced to a minimum. Feature Value| Design: | Double cascaded Czerny-Turner.
