High-Quality Broadband Design: Meeting Multi-Wavelength Requirements
Crafted with broadband optical design and high-purity fused silica fiber cores, our Broadband Fiber Collimator supports an ultra-wide spectral range from 400nm (UV) to 1700nm (NIR), with bandwidth tolerance of ±30nm for each center wavelength. The collimator utilizes aspheric C-lens or GRIN lens with optimized refractive index distribution, minimizing wavelength-dependent aberration and ensuring uniform beam divergence across the entire broadband range. The fiber core is available in various sizes (9μm single-mode, 50/62.5μm multimode) to match different light source requirements, with end-face AR coating reducing reflection loss to below 0.3%.
Precision Manufacturing Process: Ensuring Broadband Stability
Our Broadband Fiber Collimator is manufactured using precision alignment technology and hermetic encapsulation processes. The fiber and lens are aligned with sub-micron precision to ensure concentricity error <1μm, maximizing coupling efficiency for all wavelengths in the broadband range. The collimator features three optional broadband AR coating options: 400-650nm, 650-1050nm and 1050-1650nm, each with maximum reflection <0.5% in their respective ranges. The metal housing (stainless steel or aluminum) is filled with thermal conductive silicone to optimize heat dissipation, enabling stable operation across -40℃ to 85℃ temperature range.
Core Performance Advantages: Adapting to Broadband Application Scenarios
Ultraopto’s Broadband Fiber Collimator boasts low insertion loss (≤0.2dB for single-mode, ≤0.3dB for multimode) and high return loss (≥60dB), minimizing signal attenuation in broadband systems. The collimator delivers stable beam divergence (0.06-0.14mrad) and waist beam size (10.2-15.2mm), ensuring consistent performance across all wavelengths. It features excellent pointing stability and mechanical durability, with vibration resistance tested to 10g RMS (20-2000Hz). The broadband design eliminates the need for multiple wavelength-specific collimators, reducing system complexity and cost for multi-wavelength applications.
Full-Scenario Application Coverage: Empowering Multi-Wavelength Systems
Our Broadband Fiber Collimator is widely applied in communication, industrial and scientific fields. In WDM systems and 400G/800G high-speed optical modules, it enables efficient coupling of multiple wavelengths for high-capacity data transmission. For precision spectroscopy and environmental monitoring, it provides stable collimation for multi-wavelength analysis of materials and pollutants. In multi-wavelength laser systems, it serves as a universal collimator for laser processing and scientific research. The collimator also finds use in optical sensing, quantum communication and test equipment, delivering reliable broadband performance for diverse high-precision applications.
