LSM series LED light sources are ideal for fluorescence excitation and other measurements requiring narrowband illumination. The innovative optical design of the LSM LED family provides highly efficient coupling into an optical fiber, ensuring high power for fluorescence excitation where every photon counts.

LSM LEDs are available in discrete wavelengths ranging from 265-880 nm and in a warm white option with color temperature of 3689 K. LSM LEDs accommodate multiple mounting options (DIN rail, optical bench, rack) and are supplied with a rugged plastic case for carrying multiple LEDs and accessories.

The LDC-1 single channel driver/controller is required for LED operation.


  • LSM LED options -- UV, Visible, NIR and broadband wavelengths
  • LED control module -- compact single channel driver and smart controller (LDC-1)
  • Visible kit versions -- includes the controller plus 405 nm, 470 nm, 533 nm and 635 nm wavelengths
  • Additional wavelength options -- select from UV (265, 280, 310, 365 nm) wavelengths, or purchase with a mix of wavelength models (280, 365, 470 nm and 3689K warm white)
