Ondax, Inc. is the market leader in the design, manufacture and marketing of high-performance holographic optical filters, wavelength-stabilized laser sources, and high-performance, THz-Raman® Low-frequency (Low-wavenumber) Raman Spectroscopy Systems for a wide range of industrial, scientific, defense and consumer applications. Our core technology is state-of-the-art Volume Holographic Gratings (or VHGs, also known as Volume Bragg Gratings or VBGs) – which are specialized optical filters fabricated from proprietary photosensitive glass. VHGs are exceptionally versatile optical components that provide wavelength stabilization, spectral and temporal control for lasers/laser-based systems, and dramatically enhance the optical performance and resolution of spectroscopy systems. Our products enable our customers to make their lasers and optical systems, smaller, more portable, more efficient, less expensive and more environmentally stable and robust.

THz-Raman® Low-frequency Raman Spectroscopy Systems
Ondax’s patented THz-Raman® Spectroscopy Systems extend the range of traditional Raman spectroscopy into the terahertz/low-frequency regime, exploring the same range of energy transitions as terahertz spectroscopy – without limiting the ability to measure the fingerprint region. The THz-Raman spectral region covers both Stokes and anti-Stokes signals from ±5 cm-1 to 200 cm-1, (or 150 GHz to 6 THz), which contain important structural information about the molecule or crystal lattice
