The Rise of 1064nm: A New Era in SWIR Sensing

With rapid advancements in smartphones, wearables, and AR/VR technologies, the demand for short-wave infrared (SWIR) sensing is growing exponentially. Within the SWIR spectrum—spanning from 900nm to 1700nm—the 1064nm wavelength is emerging as the optimal choice for high-performance sensing applications, thanks to its unique optical advantages.

Why Choose 1064nm VCSEL?

▶ Deeper Penetration for Superior Biometric Accuracy

Compared to conventional 940nm solutions, 1064nm light has lower water absorption, allowing deeper tissue penetration. This enables superior precision and reliability in facial recognition, vein detection, and other biometric applications.

▶ Superior Interference Resistance for Reliable Outdoor Sensing

Light at different wavelengths is affected by water vapor and gases in the atmosphere, resulting in varying levels of absorption and scattering. The 1064 nm wavelength sits in a region of high atmospheric transmittance, offering excellent resistance to environmental interference. Even in bright sunlight, haze, or high-noise environments, it consistently delivers stable signal output while maintaining a high signal-to-noise ratio (SNR). This makes 1064nm an ideal choice for TOF ranging and 3D sensing, providing reliable performance in outdoor and challenging conditions.

▶ Invisible Wavelength for Enhanced Eye Safety

1064 nm wavelength significantly reduces retinal focusing and minimizes the risk of eye damage. According to IEC 60825-1:2014, the Class 1 pulsed AEL (@1 ns) for 1064nm is approximately 7 mW—nearly 9 times higher than the ~0.78 mW limit for 940nm. This enables higher-power designs while remaining eye-safe, making it ideal for safety-critical applications like children's wearables, medical monitoring devices, and in-vehicle sensing.
