Plane Ruled Grating 400l/mm 430nm-2000nm

• Extended Broadband Coverage: Optimized for the 430nm-2000nm range, spanning the entire visible spectrum and extending well into the near-infrared. This single grating enables versatile instrument design capable of addressing multiple application needs.
• Optimized 400 l/mm Groove Density: The 400 l/mm groove density provides an ideal balance between spectral resolution and light throughput across a wide wavelength range. This lower density ensures high efficiency in the NIR region where longer wavelengths require wider groove spacing for optimal performance.
• Precision Ruled for Low Stray Light: Advanced ruling techniques create smooth, accurate groove profiles that minimize scattering and ensure that the plane grating diffraction efficiency translates into clean, high signal-to-noise ratio spectral data across the entire range.
• Broadband Coating Options: Available with protected aluminum or enhanced broadband coatings specifically designed to maintain high reflectivity from the visible through the NIR, maximizing system throughput.
• Excellent Wavefront Quality: Manufactured on high-quality substrates with exceptional flatness, guaranteeing minimal wavefront distortion-critical for maintaining focus and resolution in optical systems operating across broad spectral ranges.

This versatile plane reflection grating is an ideal component for instruments requiring broad spectral coverage from visible to near-infrared:

UV-Vis-NIR Spectrophotometers: Serves as the core dispersive element for multi-purpose instruments analyzing samples across the visible and near-infrared regions.

• NIR Process Analysis: Essential for industrial process control applications, including agricultural product sorting, pharmaceutical ingredient verification, and polymer analysis where spectral signatures appear in the NIR region.
• Plane Grating Monochromator: Perfect for monochromators used in tunable light sources, allowing a single grating to cover both visible and NIR wavelengths without changing components.
• Material Characterization: Used in instruments measuring reflectance, transmittance, and absorbance of materials with spectral features spanning the visible to NIR range.
• Optical Component Testing: Suitable for test systems evaluating the performance of filters, coatings, and other optical components across broad wavelength ranges.
