Technical Excellence

The 1064nm wavelength represents one of the most important laser lines in modern photonics, serving as the fundamental output of Nd:YAG (Neodymium-doped Yttrium Aluminum Garnet) lasers, which are widely used in industrial, scientific, and medical applications. Our BP1064-35 filter's balanced 35nm bandwidth provides excellent spectral selectivity while maximizing light collection efficiency for both pulsed and continuous-wave laser systems.

With OD4 (10,000:1) blocking performance, this filter delivers exceptional out-of-band rejection critical for LiDAR applications, where weak return signals must be detected against bright ambient backgrounds. The superior blocking ensures that solar radiation and other unwanted wavelengths are effectively suppressed, enabling accurate distance measurements and 3D mapping even in challenging lighting conditions.

The 1064nm wavelength offers unique advantages for atmospheric transmission and eye-safety considerations. While this wavelength requires appropriate safety precautions, it provides excellent atmospheric transmission with minimal scattering, making it ideal for long-range LiDAR and remote sensing applications. The wavelength also penetrates biological tissue effectively, making it valuable for medical imaging and therapeutic applications.

Manufactured using advanced ion-beam sputtering technology, the BP1064-35 delivers consistent performance across the entire aperture with minimal wavefront distortion. The hard-coated surfaces are engineered to withstand high laser power densities, ensuring long-term stability and resistance to laser-induced damage in demanding applications.

The 35nm bandwidth is optimized for Nd:YAG laser applications, providing sufficient spectral width to accommodate laser line broadening and temperature variations while maintaining excellent rejection of adjacent wavelengths. This makes the filter ideal for both narrow-linewidth solid-state lasers and broader-spectrum laser diode sources operating near 1064nm.

The filter's robust construction ensures reliable performance in harsh environments, from autonomous vehicles operating in extreme temperatures to industrial laser systems running 24/7. The hard-coated surfaces resist environmental degradation, maintaining optical quality through years of continuous use.

Whether you're developing LiDAR systems for autonomous navigation, cleaning up Nd:YAG laser output for materials processing, building laser range finders for surveying applications, or conducting biomedical imaging research, the BP1064-35 provides the wavelength precision, blocking performance, and optical quality that professional laser applications demand.
