DOWA TO46S UVB LED Diode

xFxVL-1H321 is the DOWA 310nm uv led series fabricated in a TO46S semi-sphere can housing. This UVB LED diode is intended for engineers who wish to integrate an ultraviolet light source in optical instruments, sensing modules, lab equipment, and OEM UV sources.

310nm, 325nm, and 340nm Series

The UV LED series comprises the 310nm, 325nm, and 340nm versions. The 310nm uv led variant features 0.9mW radiant flux, 5V forward voltage, and 40mA current. The design enables engineers to have control of the UV source in specific analytical and experimental systems.

Narrow 6° Optical Emission

The 6° field of view facilitates directing the UV energy to the optical path instead of emitting it across a large area. In that way, the 310nm uv led becomes useful in detector calibration, excitation of samples, test chambers, sensing and optical systems using a specific wavelength.

TO46S Package with Hemispherical Lens

The TO46S metal can housing incorporates the hemispherical lens and φ5mm TO diameter. The package allows mounting this UV LED as a component in compact optical housings, test fixtures, instrument modules, and custom PCB assemblies with the through-hole type mounting.

For OEM Analytical Instruments

This 310nm uv led is a component ultraviolet light source used in spectroscopy, fluorescence excitation, curing tests, chemical and biological analysis, sensing, and special inspection devices. The product is not a lamp or consumer lighting application.

Product Details Description

The xFxVL-1H321 is DOWA UV LED diode series designed for engineering solutions requiring compact UV emission in TO46S package. The series contains 310nm, 325nm and 340nm wavelength models enabling equipment designers to choose different UV bands for optical measurement, sensing, analysis and instrument design purposes.

The 310nm uv led version is good for applications needing UVB / deep ultraviolet light source with narrow beam. The model has 0.9mW radiant flux at 310nm, 5V forward voltage, 40mA current and 6° view angle. This optical configuration is useful in case when target solution needs a narrow UV beam rather than wide-area black light.

The TO46S hemispherical can package provides a compact φ5mm metal-can design with hemi lens. This allows engineers to incorporate the LED into small optical path, sensor, sample holder, testing chamber, and lab-like equipment. The narrow beam angle can ease alignment in case when system requires sending UV radiation towards detector, material surface or any other measurement point.

This 310nm uv led can be used for spectroscopy equipment, fluorescence excitation instrument, chemical detection systems, biological analysis instrument, phototherapy equipment development, UV curing tests, material response testing, and customized optical modules. It is best fitted for precision UV LED component for OEM systems and not as a universal UV strip, black light lamp or disinfection product.

The 325nm version has 1.0mW radiant flux at 4.5V, while the 340nm version has 0.9mW at 4V. All three wavelength versions operate at 40mA. The xFxVL-1H321 series is useful for engineers who want to compare 310nm, 325nm and 340nm wavelength performance under one same TO46S design.

In order to get reliable work from the LED it needs to be driven by a proper current-based circuit. The UV LED performance can be influenced by electrical overstress, thermal issues, soldering process, handling, contamination and optical alignment. The system level testing is recommended before mass production, especially in case of spectroscopy, curing, phototherapy-related equipment or biological analysis instruments.

This 310nm uv led produces ultraviolet radiation and therefore needs special treatment. Do not look directly on the working LED and do not expose skin and eyes to UV radiation. The shielding, protective eyewear, warning labels, and safe testing procedures are needed during engineering evaluation and device integration.
