GouMax Type II dual-channel Laser Scan Analyzer (LSA-220DC) product is a multi-function power meter module. It is called "Laser Scan Analyzer" because LSA-220DC module is usually used in various applications to measure powers in conjunction with laser scanning.sweeping. It consists of high-speed power meters used to measure powers with synchronized high-speed laser sweeping. Like LSA-220A, LSA-220DC can provide wavelength reference. Like LSA-220B, LSA-220DC provide two test channels. Specifically, LSA-220DC module can provide the following functions:

• It can be simply used as two-channel power meters to measure static laser output powers
• Built-in wavelength reference
• It measures powers of high-speed sweeping laser
• It measures wavelength of sweeping laser and provides wavelength reference
• It provides power reference for relative power measurements
