Collimated LED Mounted LED LED Illumination Fiber-Coupled LED Touchscreen Driver LED Sources and Drivers Thorlabs offers a wide range of unmounted, mounted, and collimated LED sources that provide emission within the 245 nm to 46 nm spectral range. These semiconductor light sources are available in many output powers and configurations, making them useful in applications including illumination, microscopy, optogenetics, spectroscopy, and industrial curing. LED Array Lamp A selection of benchtop current controllers is available to drive our mounted and unmounted LEDs. These drivers feature internal or external modulation (via TTL input) of the LED source's pulse width and frequency. Thorlabs' 4-Channel Drivers allow for the control of multiple LEDs or our 4-Channel LED Source. Our LED sources can be easily integrated into any experimental setup. Mounted and Collimated LEDs are threaded for compatibility with lens tubes. Adapters for microscope illumination ports and liquid light guides enable these LEDs to be used with most microscope systems.
High-Power LED Sources Thorlabs' High-Power LED Sources are available in multiple packages for easy integration into any experimental setup. Select from a wide variety of wavelength output options. Single-color LEDs emit light at nominal wavelengths from 265 nm to 165 nm, while white light LEDs provide broadband emission over the visible spectrum. Dual-color and broadband LEDs allow for additional customization.
