Beam splitter prices vary widely, typically ranging from $50 for standard plate types to several hundred dollars for high-precision or polarizing cubes, depending on material, size, and coating.

General Price Ranges

• Plate Beam Splitters: Standard glass or quartz plates for visible light typically cost $50–$150 for small sizes (e.g., 12.5 x 17.5 mm) and can go up to $300–$500 for larger or UV/IR-compatible plates with anti-reflection coatings .
• Cube Beam Splitters: Optical glass cubes, including non-polarizing or polarizing types, generally range from $100–$400 for standard sizes (50–100 mm sides). High-end polarizing cubes or custom coatings can exceed $500–$800 .
• Pellicle and Polka Dot Beam Splitters: These specialty types, often used in laser systems or imaging, can cost $200–$600, depending on wavelength range and damage threshold .
• Dichroic Beam Splitters: Designed to split light by wavelength, prices vary from $150–$500 for standard visible or near-IR applications, with higher costs for broadband or custom coatings .

Factors Affecting Price

1. Material: Fused silica, calcium fluoride, and zinc selenide are more expensive than standard optical glass due to higher transmission and durability in UV or IR ranges .
2. Coatings: Anti-reflection (AR) coatings, dielectric layers, or polarization-specific coatings increase cost. Multi-layer coatings for broadband or high-power lasers are pricier .
3. Size: Larger beam splitters require more material and precision polishing, raising the price.
4. Polarization: Polarizing beam splitters are generally more expensive than non-polarizing types due to precise alignment and coating requirements .
5. Custom Specifications: Custom angles, splitting ratios, or high-power handling capabilities can significantly increase cost, sometimes exceeding $1,000 for specialized research or aerospace applications .

Suppliers and Bulk Options

• Edmund Optics and Thorlabs offer a wide range of standard and specialty beam splitters with transparent pricing online .
• Alibaba provides bulk purchasing options, often with competitive pricing for standard plate or cube splitters, including AR-coated glass and ZnSe options with warranties .
• GoPhotonics and DirectIndustry list multiple manufacturers, allowing users to request quotes for specific sizes, coatings, and polarization types . In summary, beam splitter prices are highly dependent on type, material, size, and coating, with standard small plates starting around $50 and high-precision polarizing cubes or custom devices exceeding $500–$1,000. Bulk orders or standard off-the-shelf components can reduce costs, while specialized research-grade splitters command premium pricing.
