    • 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.
