Plane Ruled Grating 50l/mm 1500nm-10600nm

• Extreme Broadband IR Coverage: Optimized for the 1500nm-10600nm range (1.5μm to 10.6μm), spanning near-infrared (NIR), short-wave infrared (SWIR), mid-wave infrared (MWIR), and long-wave infrared (LWIR)-including the critical 10.6μm CO₂ laser wavelength.
• 50 l/mm Ultra-Low Groove Density: The 50 l/mm ultra-low groove density is ideally suited for long-wave and far-infrared applications, providing optimal dispersion and diffraction efficiency for wavelengths up to 10.6μm. This extremely low density ensures maximum throughput where longer wavelengths require significantly wider groove spacing.
• Precision Ruled for Minimal IR Scatter: Advanced ruling techniques create ultra-smooth groove profiles that minimize scattering in the infrared region, ensuring that the plane grating diffraction efficiency translates into clean, high signal-to-noise ratio spectral data critical for low-light thermal emission measurements.
• IR-Optimized Coatings: Features specialized coatings-including protected gold and enhanced aluminum-designed for maximum reflectivity and durability from 1.5μm to 10.6μm, critical for applications involving high-power CO₂ lasers, thermal emission, and long-wavelength spectroscopy.
• Exceptional Substrate Quality: Manufactured on high-quality IR-grade substrates with outstanding flatness and thermal stability, guaranteeing minimal wavefront distortion across the entire spectral range-essential for maintaining focus and resolution in long-wave infrared optical systems.

This far-infrared optimized plane reflection grating is an essential component for advanced instruments operating across the near to far infrared spectrum:

• CO₂ Laser Systems: Serves as the wavelength-selective element for tuning 10.6μm CO₂ lasers used in industrial cutting, medical surgery, LIDAR, and scientific research applications.
• FTIR Spectrometers: Ideal as the primary dispersive element in Fourier-transform infrared spectrometers for materials characterization, chemical identification, and environmental monitoring across the full 1.5-10.6μm range.
• Thermal Emission Spectroscopy: Essential for characterizing thermal radiation sources, measuring material emissivity, and analyzing combustion processes where spectral features extend to 10.6μm.
• Plane Grating Monochromator: Perfect for monochromators in tunable infrared light sources, synchrotron beamlines, and spectroscopy setups requiring ultra-wide wavelength selectivity from NIR to LWIR.
• Atmospheric and Environmental Sensing: Enables detection of greenhouse gases, pollutants, and chemical agents with absorption features across the near to far infrared, including CO₂, CH₄, N₂O, and H₂O.
• Quantum Cascade Laser (QCL) Systems: Can be used for wavelength selection and tuning in QCL-based sensing platforms operating in the mid-to-long-wave infrared.
