GoPhotonics has broadened its range of Beam Splitters, showcasing a versatile selection of high-performance components. These beam splitters are designed to deliver precise, stable, and efficient light division across visible and near-infrared (NIR) wavelengths, supporting demanding applications in imaging, interferometry, spectroscopy, and laser diagnostics.
By combining advanced dielectric coatings, high-quality substrates such as UV fused silica and BK7, and optimized optical geometries, the featured solutions ensure low wavefront distortion, minimal insertion loss, and highly stable reflection/transmission ratios. Available in both plate and cube configurations, they enable flexible integration into compact laboratory setups as well as robust industrial systems.
Thorlabs BST11 - NIR Plate Beam Splitter with Controlled 70:30 Ratio
The BST11 from Thorlabs is a precision plate beam splitter designed for operation in the 700 nm to 1100 nm wavelength range. Fabricated from UV fused silica, it features a 25.4 mm diameter and 5 mm thickness, providing excellent optical homogeneity and mechanical stability.
It delivers a consistent 70:30 (R:T) split ratio at a 45° angle of incidence, ensuring predictable performance across the entire operating range. The front-surface coating defines the splitting ratio, while the wedged rear surface helps suppress unwanted interference effects and ghost reflections. This makes it highly suitable for laser-based systems, optical testing setups, and NIR instrumentation requiring stable intensity division.
CVI Laser Optics BS1-800-50-2025-45P - Laser-Optimized Beam Splitter for Precision Applications
The BS1-800-50-2025-45P from CVI Laser Optics is engineered for high-precision laser applications, offering a balanced 50:50 split ratio at a 45° angle of incidence. Designed with specialized dielectric coatings, it ensures uniform reflectance and transmittance with minimal absorption and scatter. Its optical performance is optimized for laser wavelengths, making it ideal for interferometry, beam diagnostics, and optical metrology systems where equal beam intensity and phase stability are essential.
Optoman NPBS14-AR622 - Non-Polarizing Beam Splitter with High Transmission Efficiency
The PP-UVFS-25.4-6.35-NPBS14-AR622 from Optoman is a non-polarizing plate beam splitter built on a UV fused silica substrate, ensuring high transmission and low absorption across its operating range.
Its advanced anti-reflection coatings reduce Fresnel losses while maintaining polarization-independent performance, enabling consistent beam splitting regardless of input polarization. This makes it particularly suitable for spectroscopy, imaging systems, and broadband optical setups where signal integrity is critical.
Edmund Optics 43-359 - High-Accuracy Beam Splitter for Imaging and Analytical Systems
The 43-359 from Edmund Optics is designed for precision imaging and metrology applications requiring high optical clarity and minimal distortion.
With carefully controlled surface flatness and coating uniformity, it ensures accurate beam division while preserving wavefront quality. These characteristics make it well-suited for microscopes, inspection systems, and analytical instruments where optical fidelity and measurement accuracy are paramount.
Ross Optical Industries B-CHC011 - 50:50 Cube Beam Splitter for Stable Optical Alignment
The B-CHC011 from Ross Optical Industries is a cube beam splitter featuring a 50:50 reflection/transmission ratio and a compact 25.4 mm cube design. Constructed from BK7 glass and assembled from two precision prisms, it provides excellent mechanical stability and ease of alignment.
Cube beam splitters inherently reduce beam displacement and ghosting compared to plate designs, making them ideal for interferometric setups and precision optical systems. They typically offer high surface quality and tight angular tolerances, ensuring consistent beam propagation and reliable system performance.
Supporting High-Performance Optical System Design
Beam splitters play a critical role in dividing and directing light in modern photonic systems, whether based on intensity or polarization. Available in plate and cube formats, they enable engineers to tailor optical paths for specific applications, from laser processing and spectroscopy to biomedical imaging and optical sensing.
From laboratory research to industrial inspection and advanced imaging, these beam splitters provide the accuracy, efficiency, and flexibility required to optimize optical performance across a wide range of photonics applications.
