Introduction 

 

The FlexIR Hollow Waveguide Accessory is an excellent tool for remote and specific area analysis of a 
wide variety of samples. Visible surface contamination, small area material identification and bulky 
materials too large to fit into the FTIR sample compartment are a few of the many samples and 
application types for the FlexIR accessory. 
 
The FlexIR Hollow Waveguide (HWG) Accessory is designed for high throughput, ruggedness and wide 
spectral range. The FlexIR utilizes a custom optical design with diamond-turned focus optics providing 
exceptional IR throughput. The new hollow waveguides are very durable and free from the typical 
fracture problems encountered with polycrystalline and glass core fibers. The highly reflective HWG 
fibers transmit maximum energy through the mid-IR spectral region 

 ̶

  eliminating the need for multiple 

fibers for a complete spectrum. 
 
Available probes include ATR, diffuse reflectance, and specular reflectance. The ATR probe may be 
configured with a zinc selenide, germanium, or diamond/zinc selenide composite crystal. The PIKE 
Technologies FlexIR Hollow Waveguide Accessory is built and tested for optimum performance for your 
FTIR spectrometer.
