Extensive Capabilities

Setup-Design allows easy adaptation to a multidude of different applications


• Spectral Range from Deep UV to IR (180 nm to 75µm)
• Excellent stray light rejection
• Interchangeable Grating Turrets
• 3 Gratings per Turret


• Additive & Subtractive Dispersion


The first monochromator stage disperses the spectral radiation into separate wavelength components, allowing a specific bandpass to enter the second monochromator. The second monochromator stage re-disperses the light, increasing spectral dispersion while further reducing stray light levels


In subtractive mode, the first and the second stages of spectrometer work as a tunable bandpass filter to allow only the desired portion of spectrum to pass through. A polychromatic light enters the first stage through the entrance slit and is dispersed by the first grating. The intermediate Slit acts as a bandpass filter passing only the light between wavelengths λ1 and λ2. The grating in the second Stage recombines all the dispersed light and focuses it into exit slit, producing again a polychromatic light limited to the spectral range between wavelengths λ1 and λ2.
