PRECISION TERAHERTZ OPTICS

Mastering Light Control with Metal-Mesh Technology At the core of Celtic Terahertz Technology’s hardware portfolio lies our world-renowned expertise in Quasi-Optical (QO) components and multi-layered Metal-Mesh Filters. Developed through decades of academic excellence at Cardiff University, these micro-patterned structures serve as the definitive "lens" for Terahertz radiation. Just as a high-precision camera lens focuses visible light, our optics manipulate sub-millimeter waves with exacting accuracy—defining precisely which frequencies pass, reflect, or are absorbed to ensure optimal system performance.

​

Space-Heritage Performance Our technology is not just lab-tested; it is space-proven. Leveraging the engineering heritage of historic missions like ESA’s Planck and Herschel, our optical components are built to withstand the most rigorous environments. We utilize sub-wavelength metallic grids embedded in ultra-low-loss dielectrics to achieve near-perfect spectral definition. From cryogenic vacuums to high-vibration launch conditions, Celtic Terahertz Technology delivers components that ensure signal integrity where it matters most.

​

Bespoke Engineering for Your System We understand that cutting-edge research requires more than off-the-shelf solutions. Celtic Terahertz Technology provides bespoke fabrication for specific frequency bands ranging from 0.1 to 15 THz. Whether you require high-pass filters, dichroics, polarizers, or complete quasi-optical benches, we engineer the optical heart of your instrument to deliver maximum sensitivity and focus for your unique application.
