Just slide... and work with the wavelength you need!
A innovative and creative solution for an easy and fast change between different LEDs. You only need to choose the ideal wavelength and insert the LED slide into the slot holder on the side of LS-LED. Simple as that!

High Power Excitation
LED is the perfect light source to use in fluorescence measurements. In order to maximize the sensitivity, Sarspec supplies high-efficiency LEDs with full optical power concentrated in a short wavelength band. For users that want to have different levels of output power, there’s a knob to adjust the intensity for each application.
A wide range of LEDs
For a great excitation flexibility of your LED light source, Sarspec offers a large number of LEDs with different wavelengths, covering from 255 to 1550 nm.
Multiple modes of operation and easy integration
The advanced electronics allows the LS-LED to be operated in continuous, pulsed and modulated modes. Trigger functions makes this the perfect solution for integration in your experiment. Complete it with our SPEC Hub and turn this into a turnkey solution with full control via software.
