New arrival of polarization beam splitter prisms

UltraOpto New Product Launch | Custom Polarizing Beam Splitter Prism, the Core of Personalized Optical Path Splitting for High-End Optical Systems

UltraOpto newly launches the custom polarizing beam splitter prism (custom PBS prism). Relying on polarization optics principles and military-grade processing technology, it achieves accurate separation of polarized light with no deviation and low loss. It can fully customize core parameters such as wavelength band, size, and extinction ratio according to customer needs, and also supports the integrated design of prism + wave plate. It perfectly meets the optical path control requirements of non-standard optical systems in fields such as laser systems, precision imaging, and optical communication, and is a core component for high-end customized optical applications.

The product supports customization with multiple substrates. The regular version uses N-BK7/H-K9L optical glass. Fused silica can be customized for ultraviolet scenarios. Special substrates such as αBBO/YVO₄ crystals are suitable for high-power laser/quantum optics scenarios, covering the full wavelength range from ultraviolet to communication bands. For coatings, customizations include multi-layer dielectric polarizing beam splitting films, broadband anti-reflection films, and exclusive anti-laser damage film systems for high-power scenarios, with a laser damage threshold of 10J/cm²@1064nm. The film layers are dense with strong adhesion, ensuring no peeling or oxidation during long-term use.

Three levels of precision customization are available: regular, high-precision, and research-grade. Indicators such as size, surface shape, and angle can be adjusted as needed. The extinction ratio can reach up to 3000:1 or higher, the beam splitting efficiency is >95%, and the insertion loss is <0.15dB. It adopts stress-free gluing, ultra-precision grinding, and ion beam sputtering coating technologies. The integrated version features gapless splicing without stray light, and high consistency can be ensured even in mass customization. The annual production capacity can meet the demand for ten million-level micro-components and ten thousand-level industrial components.

All products undergo comprehensive testing by high-precision equipment such as polarization state detectors and spectrum analyzers before leaving the factory, and pass rigorous tests such as high and low temperature cycles and high-power laser impact. The optical performance remains stable under temperature changes, vibrations, and high-power environments. The crystal substrate version can withstand extreme temperature changes from -200℃ to +400℃, adapting to different working conditions of industrial, military, and research grades. It is widely used in high-end scenarios such as lidar, AR/VR display, quantum communication, biomedical imaging, and optical fiber communication. It supports one-on-one customized technical solution docking, rapid prototyping of mainstream customized specifications, and stable delivery, providing exclusive beam splitting solutions for various non-standard optical systems.
