LSU2-VAR Series Variable Wavelength Light Source Unit
High Power Light Source Unit
This product adopts LED as lighting source, and brightness is enhanced with unique condensed technique. The average lifetime of LED usage is up to more than 30,000 hours, and more energy-efficient, compared with traditional Halogen light source. Also, compact design help user be handy in installation.
The Product, providing high stable and efficient power, adopts high-frequency switching constant current driver. It can effectively extend the life of LED light by accurate constant current. By operating the knob, it makes user be more convenient and easier to adjust the light, and provides current adjustment of 256-level; by using USB, it is up to the adjustment function of 4096-level current. Moreover, the dual isolated communication design enhances the reliability and safety of system communication to effectively simplify the system.
Users can trigger the input signal externally to achieve the effect of LED strobe. The maximum input frequency can reach to 20 KHZ. The built-in abnormal detection and complete system protection (temperature, power output, input and voltage, etc.) allows users to grasp the product status immediately and provides sufficient system information to help users quickly solve the problems when they occur.
This product is able to switch multiple wavelength with free collocation according users need that is able to apply in many different inspections.
Applications :
> Machine Vision, Color and Spectrum Analysis
> Fluorescence Microscope
> Raman Spectroscopy
> Optical Coherence Tomography (OCT)
> Quantum Efficiency & Film Thickness Measurement
