🟦 Beamsplitters

Precision Beamsplitters for Imaging, Laser, and Optical Instrumentation

Beamsplitters are essential components in many optical systems, designed to split a beam of light into two or more paths based on intensity, wavelength, or polarization. At Yighen Ultra Precision, we provide custom beamsplitters tailored for high-performance applications in biomedical imaging, interferometry, laser diagnostics, and optical sensing.

Whether you're designing a microscope, laser cavity, or AR display system, our beamsplitters offer unmatched accuracy, durability, and flexibility.

🔹 Types of Beamsplitters We Manufacture

• Plate Beamsplitters (Dielectric or Metallic)

• Cube Beamsplitters

• Polarizing Beamsplitters

• Non-Polarizing Beamsplitters

• Dichroic (Wavelength-Selective) Beamsplitters

• Fiber Optic Beamsplitters

• IR & UV Beamsplitters

• Custom Shaped Beamsplitters (Elliptical, Square, etc.)

We can tailor the split ratio, wavelength range, and polarization characteristics based on your specific system requirements.

🧠 FAQs

Q: What's the difference between dielectric and metallic beamsplitters?
A: Dielectric coatings provide high transmission efficiency and low absorption, ideal for high-power systems. Metallic coatings offer broader wavelength tolerance but lower efficiency.

Q: Do you provide beamsplitters for femtosecond lasers?
A: Yes, we offer custom LDT coatings specifically engineered for ultrafast laser systems.

Q: Can I order custom split ratios and shapes?
A: Absolutely. We support 10:90, 30:70, 60:40, or any custom ratio, along with elliptical, rectangular, or miniaturized geometries.

Yighen can help you design and manufacture the right optical beamsplitter for your application—whether you need one piece for R&D or a thousand for system integration.
