Quantum Cascade Laser DP-QCL5260nm-V
A Quantum Cascade Laser (QCL) is a new semiconductor laser retaining the compact size and long life of conventional devices. A major innovation in semiconductor laser theory, it extends emission beyond traditional visible and near-IR wavelengths into mid/far-IR and terahertz bands. Applications increasingly include gas detection, space communications, infrared countermeasures and THz imaging. This product integrates the QCL, active cooling and collimating optics for plug-and-play use, attractive appearance and low weight. Standard M4 and M6 mounting holes simplify assembly. Narrow-linewidth output centered at 5260nm is especially suited to nitric oxide (NO) detection.

Sunday-optics
Enclosure material: Aluminum or Copper Optical element: Aspheric lenses, two-element lenses, three-element lenses (glass), single rubber rings, and two-piece rubber rings Dimensions: M6X0.5、M7X0.5、M9X0.5、M8X0.5、M12.7X0.5
A collimating lens converts light from each point in an aperture column into a parallel, collimated beam. Lens selection depends on aberration requirements. Simple plano-convex or biconvex lenses with larger relative apertures suit low demands; achromats with smaller relative apertures suit higher demands. Collimators are a key Sunday product, available as standard or custom designs. Sandi Optoelectronics offers single aspheres, doublets and triplets.
