At Wavelength Electronics, our Product Variation (PV) capabilities bridge the gap from prototype to production, helping our partners bring products successfully to market. Once systems satisfy the end customer’s performance needs, we collaborate with design teams to optimize the solution for manufacturing to reduce the cost of goods (COGS). Whether it’s building our electronics directly on your baseplates, removing nonessential cables and accessories, or tailoring configurations for your application, our PV process ensures a smooth transition to volume production while maintaining the precision and reliability Wavelength Electronics is known for. |
CASE STUDY: Multicolor Images of Hidden Materials with Interferometry Using THz QCLs
Imaging hidden materials requires more than just a strong signal. It requires sharp data. Using three QCLs at different THz frequencies, researchers from China and the UK built RGB composite images that clearly show the distribution and identity of hidden glucose and copper oxalate. This system demonstrates detection capabilities better than microgram-level in the THz band.
With precise laser drive current and modulation from the QCL2000 OEM, researchers collected repeatable data across multiple frequency bands, revealing detailed absorption contrasts invisible to traditional imaging systems.
By using ‘fingerprint’ spectra from THz spectroscopy for various materials, inspection and identification of explosives, drugs, and biological tissues can be further explored and optimized.
