Product Description

Optical Near Infrared Volume Phase Holographic (VPH) Transmission Rectangular Gratings 

D iffraction gratings
Diffraction gratings are used to separate light into component wavelengths, are offered in both transmission and reflective varieties for use from the UV to the MIR. Our diffraction grating selection includes ruled (blazed), volume phase holographic, holographic, echelle, and a grating modulator. 

NIR Volume Phase Holographic Transmission Grating  
 
  • Five Design Wavelengths from 840 nm to 1300 nm
  • High First-Order Diffraction Efficiency
  • Resistant to Fingerprint and Aerosol Damage

Features

  • Design Wavelength (DWL) and Spatial Frequency Options:
    • 840 nm: 1200 Lines/mm
    • 900 nm: 1000 Lines/mm
    • 930 nm: 900, 1200, or 1500 Lines/mm
    • 1030 nm: 800 or 1800 Lines/mm
    • 1300 nm: 800 Lines/mm
  • High First-Order Diffraction Peak Efficiency (See Tables Below)
  • Uniform Performance Over Broad Bandwidths (See Diffraction Efficiency Graphs Below)
  • Extremely Low Scatter Between Orders (No Ghosting)
  • Dichromated Gelatin (DCG) Film Between Two Glass Substrates
  • Ideal for Spectroscopy, Optical Coherence Tomography (OCT), and Laser Pulse Compression
Near Infrared Volume Phase Holographic (VPH) Transmission Gratings are ideal for applications that require high diffraction efficiency.
