940nm Infrared Laser-20W
The 940nm infrared laser adopts imported LD, which has the characteristics of high brightness, high modulation frequency and pure spectrum. It is suitable for scientific research, photodynamic therapy, fluorescence excitation, laser display and other fields.
The light source is controlled by a touch screen, which can easily set parameters such as output power, frequency, and duty cycle. At the same time, for the convenience of use, the light source also provides an external control interface. Customers can use the TTL modulation port to synchronize the light-on and off-time of the laser with the external control signal. A key switch on the front panel ensures that only authorized personnel can access the light source.
In addition, for different applications, we can provide customized services such as divergence angle and control method. For details, please contact our engineers.
