Detecting Greenhouse Gases: Key Wavelengths and Optical Technologies
Greenhouse gases (GHGs) are a significant driver of global warming, making their detection and monitoring critical for environmental protection and climate change mitigation. Understanding the specific wavelengths at which these gases absorb infrared radiation helps in designing effective detection systems.
Innovation Award accepted by Omega Optical
August 4, 2024, Ayer, MA: Deep Ultra-violet (DUV) Transmission Gratings, especially those which transmit wavelength below 300nm were previously the domain of expensive Etched Fused Silica Gratings. No Longer! Omega Optical has introduced our patent-pending transmissive grating which uniquely transmits wavelengths below 200nm

Raman Filter Information
Omega offers several options for laser-line filtering and laser-wavelength blocking for Raman spectroscopy applications. Our hard coatings care prepared using plasma-assisted reactive magnetron sputtering for exceptional durability, low scatter, high blocking and high transmission at the desired wavelength.
General Capabilities Information
Omega Optical can manufacture filters from prototype to production. This flyer describes our primary applications, capabilities and how we can guide you to choosing the filter you need.
