Product Details
Daylight Solutions is pleased to present its mid-IR fixed wavelength laser platform offered in either CW or Pulsed versions. This platform provides the ability to switch the laser on and off via TTL input from DC to 10 kHz.
In addition to performance parameters, the center wavelength of each laser is factory set to customer specifications. This ensures wavelength accuracy of ± 30 GHz (1 cm-1) and promotes stable and robust operation.
The compact design is both lightweight and rugged with a hermetically sealed laser cavity using TEC technology for behind-the-scenes temperature control — no cryogenic cooling! The result is an easy-to-use turnkey system that’s ideal for OEM requirements.
Common applications include mid-IR illumination, thermal imaging, and OPO seeding. Please contact us to learn how the fixed wavelength laser platform can meet your application needs today.
