One-Dimensional Beamsplitter

Diffractive optical elements use diffraction for beam shaping and wavefront transformation. Precisely etched micro/nano surface-relief structures modulate laser phase or amplitude, producing diffraction/interference that reconstructs a designed intensity distribution in the far field or specified target plane. They split beams, homogenize illumination, or generate patterns. A one-dimensional splitter is a typical DOE. Definition: it divides one incident laser beam along one dimension into equally spaced 1×N sub-beams with a defined divergence angle. Applications include machine vision, motion-sensing technology, sensing, and aerospace; see the schematic below. Key parameters: 1. Operating wavelength. Diffractive splitters are wavelength-sensitive and designed for a specific laser wavelength, such as red or green. Custom substrates include fused silica, silicon, and ZnSe. 2. Split count. Linear 1×N spot arrays can have custom one-dimensional counts such as 2/3/5/9/11. 3. Split angle. Adjacent-beam angles are customized, with strong angular-tolerance control and consistent spot arrangement. 4. Energy uniformity. Output intensity differences are kept very small, with no obvious beam-to-beam brightness variation. 5. Diffraction efficiency. The desired spots' energy divided by total energy measures utilization. 6. Zero-order suppression reduces the bright central zero-order spot and avoids interference from it, especially important for even split counts. Working principles: 1. Phase modulation. Specific etched micro/nanostructures, effectively a complex grating, precisely modulate the incident laser wavefront. 2. Splitting/replication. Diffraction forms discrete spots in the far field or lens focal plane. Each sub-beam is a precise replica of the input, retaining diameter, divergence, polarization, and other optical properties apart from propagation direction, as stated. Customization/manufacturing: one-dimensional splitters are a core independently developed diffractive product. The company describes itself as a Chinese independent developer with years in micro/nano-optical manufacturing. Its engineers cover optical design, micro/nanofabrication, and precision inspection, with extensive practical DOE experience. An integrated lithography/dry-etching platform provides independent design-through-production capability and control of core processes. Customer laser parameters, working distances, and system-space constraints guide custom split counts, output angles, operating wavelengths, and substrates. Optimization targets spot-array uniformity and zero-order suppression to prevent uneven splitting and angle offsets. A dedicated engineer can assist from the initial phase, reducing prototype trial-and-error costs. Flexible delivery serves small nonstandard research/university prototypes and advanced experimental development as well as standardized high-volume industrial orders. Every finished device undergoes full item-by-item inspection of diffraction efficiency, beam uniformity, split-angle precision, and other core metrics. Formal test reports can accompany delivery, ensuring batch consistency. A complete domestic in-house line improves production turnaround. Dedicated one-to-one support responds efficiently to presales changes, on-site setup, and after-sales corrections. The company presents itself as a trusted Chinese one-dimensional splitter supplier.
