1950nm SLD Benchtop Light Source
Idealphotonics' modular laser control is based on an advanced microprocessor control system, combined with high-precision ATC and ACC (APC) control circuits to achieve highly stable laser output, while ensuring that the light source is quick and intuitive to operate. We can also provide corresponding communication interfaces and control software according to user requirements to achieve computer control. This light source uses a one-key recovery function (Run/Stop button) to effectively help customers return to the previous working state. This is a highly integrated modular system light source that uses PC-side software intelligent control. Customers can set the required working temperature and current according to their needs. It is very suitable for experimental scientific research and production testing. In addition, we need to modulate the laser in some application fields. We have connected two external modulation ports, one for high frequency and one for low frequency, to better meet customers' needs for multiple uses of one machine.
Product features:Support one-key restore function (no need to restart and preheat)、 Software remote control, intelligent control、 Stable output power, continuously adjustable、 Compact structure、 High-precision ACC and ATC control circuit、 Built-in high and low modulation bandwidth BNC interface
Part Number:--
Application area:Fiber optic transmission system、 Fiber optic gyroscope、 Fiber optic sensor、 Optical coherence tomography、 Test light source
