Advantest TQ8111 Light Source

The Advantest TQ8111 is an LED-based precision light source engineered for optical testing and characterization across the visible to near-infrared spectrum. It delivers stable, calibrated output across two independent multimode fiber channels, spanning 400 nm to 1750 nm with power levels ranging from 0.01 µW to 10 W. The instrument serves research and development environments where consistent, accurate optical measurements are critical for component and system characterization.

– Technical Specifications

• Type: LED Light Source
• Wavelength Range: 400 nm to 1750 nm (0.4 µm to 1.75 µm)
• Output Power: 0.01 µW to 10 W
• Output Channels: Two (multimode fiber)
• Input Power: 110 V / 60 Hz (USA)

– Key Features

Dual-channel architecture enables simultaneous or independent optical sourcing. Multimode fiber output ensures broad compatibility with standard test fixtures and measurement systems. The extended wavelength range spans applications from visible through SWIR imaging and sensing. Wide dynamic power range accommodates both low-level signal detection and high-power optical characterization tasks.

– Operating Requirements

The unit must operate in horizontal position with unobstructed ventilation ports to maintain thermal stability. Installation requires connection to a grounded electrical outlet; extension cords must include safety ground terminals. Power cables must match the specified voltage rating; grasp the plug when disconnecting—do not pull on the cable itself. Hands must remain dry during power plug handling. Operation is prohibited with the enclosure open.

Maintain the instrument in clean, vibration-free environments away from magnetic fields and sudden temperature fluctuations. Avoid areas with moisture, dust, or dirt contamination. When storing or transporting, secure the unit to prevent tipping.

– Maintenance and Calibration

Calibration must be performed by Advantest or an authorized service center. Recommended calibration interval is one year. Standard AC adapters are no longer included with this product.
