Hedgehog™ Mid-IR Laser: High-Speed, Versatile Tuning

The Hedgehog Mid-IR Laser is the latest generation tunable laser head from DRS Daylight, perfect for OEM or laboratory applications. With its TEM₀₀ beam quality, high power, small size, CW or pulsed output, and unparalleled spectral repeatability, the Hedgehog laser is a one-of-a-kind device based on well-proven External Cavity Quantum Cascade Laser^TM technology.

High-SNR data acquired quickly is advantageous for applications using molecular spectroscopy. Wide-ranging mid-IR tuning is especially advantageous when exploring several molecules or an absorption feature with a large dynamic range.

The Hedgehog system's advantages are its low noise output, great spectral and spatial beam quality, and wide, fast tuning across the mid-IR spectrum. Accessing this performance is simple because of its sealed, alignment-free design, standard GUI, and SDK.

Choose between the following three basic Hedgehog models: Hedgehog (tunes up to 200 cm^-1), Hedgehog-UT (tunes up to 400 cm^-1), and Hedgehog-LT (tunes up to 30 cm^-1).
