Hedgehog™ Mid-IR Laser: Advanced Performance with Broad Tuning Range

Charming name. Impressive capabilities. Perfect for both laboratory and OEM applications, the Hedgehog Mid-IR Laser represents DRS Daylight's latest tunable laser head.

Utilizing the established External Cavity Quantum Cascade Laser^™ technology, the Hedgehog laser combines a compact size with tuning speeds exceeding 5000 cm-1/second, options for continuous wave or pulsed output, high power, TEM00 beam quality, and unparalleled spectral repeatability.

Molecular spectroscopy applications both reap the benefits of rapid, high-SNRdata acquisition. The ability to investigate various molecules, or to assess an absorption feature with extensive dynamic range, is further enhanced by wide mid-IR tuning.

The Hedgehog system delivers these benefits with its broad, fast tuning across the mid-IR spectrum, low-noise output, and high spectral and spatial beam quality. Its sealed, alignment-free design and included GUI and SDK as standard features make it easy for users to access this performance.

Choose between the Hedgehog (which tunes up to 200 cm^-1), Hedgehog-UT (tunes up to 400 cm^-1), and Hedgehog-LT (tunes up to 30 cm^-1) standard models.
