The Model 262-TR Transmissometer / Reflectometer is a precision instrument designed to accurately measure the transmissivity and reflectivity of a wide range of samples. The system consists of a sample measurement stage fiber optically coupled to a signal processing and display console. The sample stage is built on a rigid rail system for stability and is adjustable to accommodate a wide range of optics. The console includes a large, bright LED display for the Transmissivity/Reflectivity measurements allowing operators to quickly and reliably make measurements. The console also includes a USB port on the rear for remote monitoring of Model 262-TR measurements by an external PC.
