Infrared Sources for Industrial & Safety Applications

Liquid Analysis using ATR


Attenuated Total Reflection (ATR) spectroscopy is a technique where a beam of infrared light is passed through a crystal which allows total internal reflection. The infrared beam penetrates the surface of a liquid or solid sample, and the eventual signal profile received at the detector can be used to characterize the sample.


The effectiveness of ATR spectroscopy has been further enhanced by use in conjunction with Fourier Transform Infrared Spectroscopy (FTIR). Today, ATR finds increasing acceptance as a measurement technology for various industrial applications, e.g. quality control of lubricants, cutting fluid, and other liquids such as gasoline, milk, chemical reagents, etc. A number of medical applications, such as glucose measurement in blood or urine, also rely on the ATR spectroscopic principle.


Axetris Infrared sources provide excellent emission characteristics in the mid-IR range for such applications, and the Axetris team also delivers competent support in achieving highly collimated beams by using suitable reflectors and optics.


Advantages of Axetris Infrared Sources :

- High emission at 4.26μm

- Small size

- Fast electrical modulation (Modulation frequency: >10Hz)

- High modulation depth 

- Low power consumption 

- Long lifetime 

Axetris offers solutions by providing a portfolio of IR sources with several reflector with /or without integrated windows (BaF2, CaF2, GeART100).
