High-resolution Czerny-Turner spectrographs, aberration-corrected spectrometers, and multiple stage configurations for researchers demanding maximum spectral purity.
Technical Guide
Monochromators and spectrographs are the foundation of spectral selection. By utilizing diffraction gratings, they select narrow wavelength bands from broadband sources or disperse complex light onto multi-element detectors.
The Zolix Omni-λ series utilizes the asymmetrical Czerny-Turner design. Broadband light enters through an entrance slit, is collimated by a curved mirror, and is directed onto a diffraction grating.
The grating separates the spectral components by angle. A focusing mirror then focuses the dispersed light. Depending on the exit port:
Pairing your monochromator with the correct grating determines the system spectral range, dispersion, and resolution. Grating turrets support dual or triple mounts, enabling automatic switching between UV-optimized (e.g. 1200g/mm, blazed at 300nm) and NIR-optimized (e.g. 600g/mm, blazed at 1.0μm) models.
By linking a broadband lamp (Xe, Halogen, Deuterium) to the input slit, the system outputs high-purity monochromatic light. Critical for characterizing detector Quantum Efficiency (QE), solar cells, and photochemical reactions.
Analyzing inelastic Raman scattering or Photoluminescence (PL) emission. Pair with deep-cooled CCD arrays (like our sCCD01AM) to capture weak molecular signatures, structural bounds, and semiconductor recombination kinetics.
Precise transmission, absorption, and reflection measurements. Perfect for analyzing out-of-band blockings, steep cut-on edges, and peak transmission characteristics of dichroic mirrors and bandpass filters.
Resolving narrow atomic emission spectra in gas discharges, plasma reactions, and pulsed laser pulses. Long focal paths (like the 750mm Omni-λ750S) resolve lines separated by less than 0.03 nm.
Determine model numbering and select entrance/exit slits and camera ports. Use our dynamic 2D port mapper tool to select standard, IR, silver-coated, or dual entrance and exit layouts.
Build and analyze your monochromator's triple or dual grating turret. Explore our comprehensive holographic/ruled database, run automated spectral overlap gap analysis, and load optimized UV-Vis or IR presets.
