产品介绍

Product Overview:

PLCTS offers a range of monochromator platforms featuring a core asymmetric horizontal Czerny–Turner optical layout with astigmatism correction for improved spectral line symmetry and optical resolution, and secondary dispersion cancellation to effectively reduce stray light. Configurable with multiple gratings as needed, these monochromators provide fully automated broadband testing via PC control of grating exchange, filter switching, and wavelength scanning. USB hot-plug support enables plug-and-play convenience with high transfer speeds. The input port is compatible with PLCTS light sources and optional standard fiber-optic interfaces for fiber input/output. Designed for out-of-the-box usability, these systems combine ease of use with superior performance.

Key Advantages:

  • Asymmetric horizontal Czerny–Turner layout with astigmatism correction
  • Secondary dispersion cancellation for minimal stray light
  • Flexible multi-grating configuration per application
  • PC control of grating exchange, filter switching & wavelength scanning
  • ● USB hot-plug support for plug-and-play with high transfer rates
  • ● Input port compatible with all PLCTS light sources
  • ● Optional standard fiber-optic interface for fiber I/O
  • Ready-to-use out of the box, with user-friendly design and high performance
