Why Choose This Beam Splitter Cube?

• High Polarization Contrast: Transmittance and reflectance values are optimized for clean beam separation, ensuring minimal cross-polarization leakage.
• Dual Functionality: Functions as both a beam splitter (splitting one beam into two orthogonal polarizations) and a beam combiner (coupling two orthogonally polarized beams into one) when the light path is reversed.
• Anti-Reflection Coating: AR coatings on all right-angle entry/exit faces minimize surface losses and ghosting for cleaner optical performance.
• Compact Mini Form Factor: The small cube dimensions make integration into tight optical assemblies and prototype setups easy.
• Precision Optics: Built to exacting tolerances for consistent, repeatable results in laboratory and professional photonics environments.

Common Applications

• Red laser beam management (635nm, 650nm, 660nm systems)
• Interferometry and holography setups
• Optical coherence and sensing instruments
• Polarimetry and optical testing rigs
• Laser communication and fiber optic systems
• Research, education, and photonics prototyping

Frequently Asked Questions

Q: What wavelength range does this PBS cube lens support?

A: This polarizing beam splitter cube is optimized for the 630nm–660nm wavelength range, making it ideal for red laser systems operating at common wavelengths such as 635nm, 650nm, and 660nm.

Q: Can this beam splitter cube be used to combine two beams as well as split them?

A: Yes. When the light path is reversed, the PBS cube can couple two orthogonally polarized beams into a single output beam, making it highly versatile for both splitting and combining applications.

Q: What sizes are available for the PBS-660-D10?

A: The cube is available in two sizes: 12.5 × 12.5 × 12.5 mm and 10 × 10 mm. Please verify your required size at checkout or via product variant selection.

Q: What coatings are applied to this optic?

A: The glued internal surface features a PBS (polarizing beam splitter) dielectric coating, while all exterior right-angle faces are coated with anti-reflection (AR) coating to reduce surface reflections and improve overall transmission efficiency.

Q: Is this suitable for professional or laboratory use?

A: Absolutely. With Tp > 95%, Ts < 1%, Rs > 99%, and Rp < 5%, these optical performance values meet the demands of professional optical benches, research labs, and precision photonics instrumentation.
