Laser Beamsplitter Plate with Customizable Thickness and Coating
A Beamsplitter Plate is a thin optical element designed to divide an incident light beam into reflected and transmitted components with precise ratio control. Compared with cube beamsplitters, beamsplitter plates feature compact thickness, lightweight structure, and reduced absorption, making them ideal for integration in space-limited optical systems.
Feature:
- Precise reflection/transmission ratio control (e.g., 50/50, 30/70, custom ratios)
- High surface accuracy ensures low wavefront distortion
- Broadband or narrowband dielectric coating options
- Minimal absorption for high laser damage threshold
- Lightweight and thin profile suitable for compact systems
- Custom sizes, shapes, and coating designs available
Application: Widely applied in interferometry, imaging, laser systems, display optics, and optical testing setups.

Beamsplitters are typically manufactured from high-quality optical glass or crystal materials and coated with specialized optical films to achieve precise beam-splitting performance. Based on their splitting principle, beamsplitters are categorized into polarizing beamsplitters and non-polarizing beamsplitters:
- Polarizing beamsplitters (PBS): Separate light based on polarization state, ideal for laser polarization control and imaging systems.
- Non-polarizing beamsplitters (NPBS): Divide light by intensity or wavelength without significantly affecting polarization, suitable for general-purpose beam splitting.
Common types include plate beamsplitters and cube beamsplitters. Through different coating designs, the reflection/transmission ratio and polarization characteristics can be precisely controlled.
Key Advantages:
Beamsplitters offer accurate control over light propagation and energy distribution, providing versatile and efficient solutions for optical interference measurement, laser beam shaping, imaging, and scientific experiments. They enhance the performance and functionality of modern optical systems.
