Wavelength lineup


Ushio's epitex series has been producing and selling SWIR LEDs for over 15 years, and has achieved the world's highest output and efficiency.
We can offer the customization of SWIR wavelength in increments of 10nm with a variation of up to ±10nm to suit your needs.
The ideal optimal solutions are ready for each customer's application with variations in SWIR wavelength (1000nm to 1750nm),
chip size, lens type, etc.

We have released a new website dedicated to SWIR LEDs. To learn more about SWIR LEDs, please visit https://swir-led.com.
