LED, picosecond & calibration sources
Multiwavelength LED Source System
Modular LED heads spanning UV, visible and near-infrared wavelengths, with controller options for manual illumination or programmed multi-channel operation. Select heads and drive current around the required wavelength and optical power.
Best suited to
Discrete-wavelength excitation, fluorescence and repeatable LED illumination experiments.
Selecting a configuration
Choose the LED wavelength and rated current first, then the controller functions. The MLED4S timing features and interfaces should not be assumed for the simpler MLED-CONTROLLER-X.
Measurement & configuration
- 24 nominal wavelengths from 290 to 1030 nm.
- MLED4S: four channels, 1 kHz PWM, timers and programmed sequences.
- MLED-POST1 to POST4 mounting options for source-head arrangements.
