Low Stray‑Light, Reliable Dispersion: Holographic Diffraction Gratings for Spectroscopy Instruments
When accurate spectral separation matters for your spectrometer system, every groove counts. The METICULAB™ Holographic Diffraction Grating is manufactured via holographic interference lithography, delivering low stray‑light performance without ghost lines. Available in plane and Rowland concave types, with optional aluminum alloy mounting base for quick integration into analytical spectroscopy equipment.

Why METICULAB™ Holographic Gratings?
- Holographic Interference Lithography: Produce ultra‑low stray‑light performance, eliminate ghost‑line artifacts common with mechanically ruled gratings.
- Strict Optical Tolerance Control: Precise groove density, wavelength and surface figure guarantee consistent spectral dispersion performance.
- Flexible Material & Coating Selection: N‑BK7 for UV‑Vis‑NIR, Fused Silica for deep‑UV; Aluminum / Gold / Silver coating for different spectral bands, optional protective overcoat for anti‑oxidation and moisture resistance.
- Full Customization Available: Custom physical dimension, groove density, reflective coating and pre‑mounted aluminum alloy housing for fast system assembly.
- Full Inspection Before Shipment: Every grating goes through systematic optical test, ready for integration into commercial instruments and research setups.
