The CEL-FES300 is an upgrade to previous photocatalytic Xenon light sources, designed as a multi-functional solution that enables a variety of experimental setups and configurations within a single machine. It is ideal for researchers requiring spatial flexibility, precise beam control, and the ability to conduct multiple types of photocatalytic and photoelectrochemical experiments.

Key Technical Features:

• Multiple Functionality: Supports 300W Strong Photocatalysis, Optical Fiber Output, and Simulated Daylight experiments, all in one system.

• Solar Simulation: Capable of replacing conventional solar simulators, featuring light stability of less than 1 percent and built-in AM1.5 standard filtering.

• Fiber Output: Optical fiber output eliminates spatial limitations and allows for square spot size adjustment (from 10 by 10 mm to 60 by 60 mm).

• High Uniformity: The output uniformity of the fiber square spot is less than 5 percent (for areas smaller than 40 mm).

• Fast Electronic Control: Includes a high-precision electronic shutter (0.01 second precision), allowing arbitrary setting of opening, closing time, and cycle numbers, which is crucial for photocurrent testing.

• Wide Spectrum: The total luminescence spectrum ranges from 300 nm to 2500 nm (No ozone). The fiber output simulates the solar spectrum from 350 to 1100 nm.

• Superior Stability: The optical output stability via fiber is plus or minus 0.5 percent.

• Key Applications: Essential for: Photoelectrochemistry (PEC), Solar Cell Testing, Photocatalytic Water Splitting for Hydrogen/Oxygen, $\text{CO}_2$ Reduction, and Photodegradation of gaseous and liquid pollutants.

• Optional Accessories: Supports the LMP400 Automatic Lifting Platform and the LB70 Optical Dark Box.
