System Description:

• The QE-R standard system has all the necessary functions required by IEC 60904-1, 60904-7, and 60904-8:
• The high-efficiency light collection system has a light collection effect of>70%, which is more than an order of magnitude higher than traditional lens light collection systems in terms of light intensity, providing excellent signal-to-noise ratio and measurement accuracy for the system.
• Czerny Turner multi grating single light analyzer has low stray light<10-5, high stability, fast scanning, and a spectral range of up to 200 nm~2000 nm.
• Dual beam optical path design:
• Signal multiplexer, exclusively integrated with computer-controlled signal switch, avoids damage caused by pulling and pulling signal line connectors, and reduces maintenance and consumables costs.
• The excellent signal-to-noise ratio of up to 100 dB is the result of overall system optimization. Customers do not need to read the thick operation manual of general lock-in amplifiers, nor do they need to optimize the measurement parameters themselves, avoiding the trouble and errors of human operation.
• In DC measurement mode, customers do not need to disassemble any hardware equipment, and can directly integrate the multi power meter into the system in a modular manner, greatly simplifying hardware space and the inconvenience of disassembly and assembly.
• High uniformity reference detector.
