Price list for adjustable light attenuators

Adjustable light attenuators typically range from $20 for basic fiber-optic models to over $2,000 for high-precision electronic or laser beam attenuators.

Overview of Price Ranges

• Basic Fiber-Optic Variable Attenuators: Manual VOAs for singlemode fiber with attenuation ranges of 1–30 dB usually cost $20–$150. These are compact, connectorized devices suitable for lab testing, network installation, or system maintenance, offering low insertion loss and manual adjustment via a screw or dial .
• High-End Electronic or Benchtop VOAs: Devices with integrated optical power meters, digital displays, and precise control modes (constant attenuation or constant output power) can range from $500 to over $2,000, depending on features, wavelength range, and power handling .
• Laser Beam Attenuators: Precision prism-based attenuators for high-power laser applications (up to 200 W) are typically more expensive, often $300–$1,500, depending on prism material, coatings, and power rating .
• RF or Acoustic Attenuuators: While not optical, adjustable RF or acoustic attenuators for signal or noise reduction can vary widely, from $50 for small lab units to several hundred dollars for industrial-grade models .

Factors Affecting Price

1. Attenuation Range: Wider ranges (e.g., 0–50 dB) or finer step resolution increase cost.
2. Precision and Stability: Devices with ±0.1–0.2 dB accuracy or low insertion loss are more expensive.
3. Type of Adjustment: Manual screw/dial models are cheaper, while electronic or motorized VOAs with digital control are pricier.
4. Application: Telecom, laboratory, or high-power laser applications require more robust and precise devices, increasing cost.
5. Connector Type and Wavelength Compatibility: FC/PC, LC/APC, or AR-coated prisms for specific wavelengths can affect pricing. In summary, for general lab or telecom use, expect $20–$150, while high-precision or high-power applications can exceed $1,000–$2,000. Choosing the right attenuator depends on the required attenuation range, precision, and application environment.
