Resolve the line, not just the band

Resolve the line, not just the band

Gas-phase absorption lines are narrow and, at low pressure, largely unblended. That makes them highly specific — provided the measurement resolves them. Comb-based sources deliver both the resolution and the broad coverage needed to identify several species in one acquisition.

What the comb brings

  • An inherently calibrated frequency axis, so line positions are absolute rather than relative to a scan.
  • Broad coverage in a single acquisition, so several species are quantified at once.
  • Ultralow relative intensity noise, which sets the detection floor of the instrument built around the source.
  • A turn-key OEM source for developers integrating gas sensing into a product.
