For Spectroscopy at Speed, Without Compromise™.
Molecular spectroscopy applications benefit from rapid, high Signal-to-Noise Ratio data acquisition. This demands fast-scan mid-IR lasers delivering high-quality light. Until now, high tuning speed has come with compromises. The new Hedgehog from Daylight Solutions changes this. For the first time, fast tuning and high-fidelity output is available from a compact, robust mid-IR laser.
Hedgehog is built on Daylight’s field-proven Quantum Cascade Laser (QCL) technology. Available center wavelengths span the mid-IR spectrum from < 4 to > 13 μm, and Hedgehog can provide pulsed or CW output2. Users can select from three model types (HHG, HHG-UT, or HHG-LT) depending on their application power and tuning range requirements. All models include: a GUI option for ultra-quiet CW operation; high wavelength repeatability; and multiple tuning modes.
Hedgehog’s small size and rugged design make it ideally suited to either laboratory use or OEM integration. Each Hedgehog is shipped with a compact, easy-to-use SideKick™ multi-function QCL controller. All control functionality is via USB/Ethernet connectivity and an included GUI and SDK command set. Daylight‘s proprietary HFQD™ (High-Fidelity QCL Drive) circuitry also protects your QCL chip.
With Hedgehog, high-speed, high-quality mid-IR spectroscopic data acquisition is now a reality. Hedgehog brings new capabilities to a wide range of molecular sensing applications including: process control; detection of pollutants, chemical and biological agents; time-resolved spectroscopy; and cellular imaging. Please contact us today to learn how Hedgehog, and our highly experienced team, can help your application.
