CO2 Composite Cleaning Critical for Photonic Devices
Advanced CO2 composite spray cleaning is an efficient and adaptable process for build-clean and maintain-clean protocols. A common aspect of photonic devices is the presence of critical components that emit, transmit, modulate, amplify, divide, switch or otherwise process light over the whole spectrum from ultraviolet over the visible to the near-, mid- and far-infrared. Particles and residues absorb, attenuate or obscure light. Because of this, critical light-processing elements of...
