The New Light in Thermal Imaging
infrared for EVERYONE

Mid-IR Lasers

Mid-IR spectroscopy is a powerful tool that has been in use for decades for the detection, quantitation and identification of virtually any organic material. Quantum Cascade and Interband Cascade lasers (QCL, IBL) are fabricated using semi-conductor manufacturing technologies for the production of mid-infrared light. This revolutionary laser technology now puts us on the brink of being able to routinely detect, measure and identify virtually everything that surrounds us, from the air we breathe, to the food we eat, to the objects we touch. The impact will be far reaching: improving our environment, making us safer and healthier, helping us avoid harm, and improving our quality of life. Imagine being able to detect the onset of an illness or disease before any noticeable symptoms just by simply sampling your breath, or avoiding an allergy by checking your food before eating.


RedShift is applying its expertise in micro system, tunable filter, and laser technologies to help move this revolution forward.

Leader in Infrared Tuning


RedShift’s TopTIR™ technology is based on themo-optic tuning and has been applied to applications as diverse as telecommunications, thermal imaging and spectroscopy. Our TopTIR optical filters are solid state devices with no moving parts, enabling compact and reliable components and systems. We fabricate our filters using MEMS (Micro Electro Mechanical Systems) technology, the same technology found in most personal electronics devices used today. We then integrate our TopTIR filters into solutions for the OEM and end user, helping our customers solve problems and improve their competitiveness in a broad range of markets and applications.


RedShift has now developed a broadly tunable Mid-IR laser solution by combining our tunable filters with QC lasers.


These TopTIR lasers are specifically designed for the spectroscopy OEM looking to enter new markets or provide higher performance solutions in existing FTIR or TDLAS applications.
