Reflection Gratings - Ruled

Reflection Gratings - Ruled

These replicated diffraction gratings are produced from high quality ruled master gratings and are intended for use in spectrometers and monochromators where low cost and high efficiency are of primary concern.

In general, ruled gratings have a higher peak efficiency than holographic gratings. Applications that may require a ruled grating may include:

  • Fluorescence excitation
  • Analytical Chemistry
  • Life Sciences
  • Telecom Applications
  • Physics
  • Education
  • Space Sciences

Ruled diffraction gratings, due to their “sawtooth” groove profile, have a relatively sharp peak around their blaze wavelength while some holographic gratings have a flatter spectral response. Applications centered around a narrow wavelength range could benefit from a ruled grating blazed at that wavelength.

Damage Thresholds
Any standard Optometrics grating is available with either P-type or CW-type construction for higher damage thresh­old performance. They can also be produced on substrates with a lower coefficient of thermal expansion (Low CTE) for better stability. No damage threshold minimums apply to gratings with an overcoat.  Low CTE and P-type gratings are available on a custom order basis.  Please contact us for pricing.
