Please note that the LSM LED modules require the LDC-1 controller.

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.

The LSM LEDs are controlled by the LDC-1 compact single channel driver and controller packed with features and functionality. The LDC-1 controller has an easy to use touchscreen for displaying and accessing key information stored in the LSM LEDs. Proprietary electronics provide stable, high-current operation in continuous, pulsed, and modulation modes.

When using the internal modulation mode, the user can select sine, triangle or square waveforms. The LDC-1 also enables LSM LED control using an external source such as a function generator or a trigger/modulation signal from a spectrometer or other electronic device.

  • UV, Visible, NIR and broadband wavelengths
  • Passive cooling design
  • Smart controller with color LCD touch screen
  • Multiple mounting options (DIN rail, optical bench, rack)
  • External trigger option (function generator or trigger signal)

Please Note:  

The actual spectra for the LEDs may vary from those reported here due to differences in operating parameters and variations in the manufacturing process.

The peak wavelength may vary slightly from the nominal wavelength depending on the spectrometer configuratoin used to measure the LEDs.

UV protective eyewear should be used when working with UV LEDs (265, 280, 310, 365, 386 nm) to avoid eye damage.
