Overview
The AXA40n1 Collinear Adapter is an accessory for the Luna T-Ray 5000 pulsed terahertz measurement system. The T-Ray 5000 is a compact, rack-mount system with fiber-coupled, replaceable sensor heads, which allows the system to be configured for a given application. The adapter couples a stand-alone transmitter and receiver head so that they operate as a collinear reflection transceiver.
Because the transmitter and receiver share the same lens, reflection measurements can be acquired directly. The manufacturer reports spatial resolution down to 100 microns with this arrangement using a 1 in. focal length lens, and describes the transceiver configuration as suited to reflection tomography.
Alignment pins provide positioning of the heads. The adapter has two lens ports, so it can be assembled in a right- or left-handed orientation, and lenses can be changed without tools. When used with an HTS40nm transmitter and an HRS40n1 receiver, the assembled collinear transceiver provides over 3.5 THz of bandwidth and 60 dB of signal-to-noise ratio.
