325nm uv led DOWA TO18 310nm 340nm
Product Details Description
The xFxVL-1H411 series is a DOWA UV LED diode intended for engineers that need compact ultraviolet light sources in a TO18 package. The series comes with three wavelength options, which are 310nm, 325nm, and 340nm. Thus, the manufacturer allows selecting different UV bands depending on the target application of the optical, sensing, and analysis system.
The 325nm uv led is the most appropriate choice for those projects that need a deep ultraviolet / near-UVA light source in a small metal can package. This UV LED delivers radiant flux equal to 1.4mW at 325nm wavelength, works at 4.5V forward voltage, consumes 40mA current, and features 40° view angle. The hemi lens helps forming the emission pattern for compact optical paths, small test chambers, sensor modules, and laboratory instruments.
It is important to note that the 325nm uv led is not the decoration UV lamp, nor the high-power curing lamp. This is the precise UV LED component for OEM systems, such as spectroscopy equipment, fluorescence excitation instruments, chemical detection tools, biological analysis devices, UV sensing systems, etc. It is practical for those engineers that need a compact UV emitter with specified electrical and optical parameters.
The 310nm option can be selected when shorter UVB wavelength is required, while the 340nm one – when a longer UVA is needed. In case of middle wavelength – it is possible to use the 325nm uv led, because it covers projects with UV output around 325nm. The final optical performance will depend on the driver circuitry, thermal management, lens design, target distance, detector response, and system calibration.
To ensure stable work, this UV LED should be driven correctly with proper current control and adequate thermal management. Even with such low current as 40mA, UV LED performance can be impacted by heat, electrical overstress, reverse voltage, soldering, and optical contamination. Therefore, engineers should check the LED in the final system before launching mass production.
This 325nm uv led delivers ultraviolet radiation and should be used correctly. Do not look directly at the working LED and do not expose skin and eyes to UV radiation. Please use appropriate protective eyewear, shielding, warning labels, and other measures to ensure safety during testing and integrating the component into equipment.
