Luna’s T-Ray® 5000 is the first compact pulsed terahertz measurement system that is robust enough to be deployed in an industrial environment. With Luna’s T-Ray® 5000 HTS/HRS transmitters and receivers, the T-Ray® 5000 can be configured to fit your specific application.

Operating in either reflection or transmission mode, the fiber-coupled transmitter/receiver heads deliver a picosecond duration time-domain terahertz pulse, allowing high speed, scanned images to be easily produced. Coupled with an HRS40n1 receiver, the transmitters provide bandwidth above 3.5 THz and signal to noise ratio above 70 dB (HTS40n1/2) or 55 dB (HTS40n3)

The T-Ray® 5000 HTS40n1 Transmitter Type 1 provides high output power with high spectral bandwidth. The enhanced low frequencies provide higher material penetration for imaging voids and disbonds in high-frequency scattering media. By maximizing low-frequency power, the HTS40n1 is ideal for applications where high material penetration is required for imaging, particularly in scattering or absorbing materials.

The T-Ray® 5000 HTS40n2 Transmitter Type 2 balances high output power with high spectral bandwidth and minimizes features following the pulse to allow high quality images and detection of multiple layers in reflection with less need for post processing of the waveform. By balancing bandwidth and power, the HTS40n2 is ideal for applications where both high-resolution imaging and broad spectral range are desired.

The T-Ray® 5000 HTS40n3 Transmitter Type 3 provides uniform signal to noise over an extended range for high-resolution spectroscopy, while minimizing waveform distortions after the pulse to allow high resolution temporal measurement of layer thicknesses without the need for post processing of the waveform. By providing a uniform signal to noise over a broad bandwidth, the HTS40n3 is ideal for applications where both high resolution and broad spectral range are desired.

The T-Ray® 5000 HRS40n1 Receiver provides high spectral bandwidth when coupled with any of the HTS40nm transmitters. The HRS40n1 provides bandwidth over 3.5 THz and signal to noise ratio above 70 dB. By embedding amplification close to the signal source, the receiver is able to produce high signal to noise, and eliminate the need for a lock-in amplifier.
