Online "focusing" method for collimator in optical communication

At present, there are two main online "focusing" methods for collimators in the optical communication market:

1. Traditional mirror debugging method (by means of power meter, mirror, etc.)

2. Debugging method based on beam analyzer (mainly slit and camera beam analyzers), and automation equipment based on camera beam analyzer.

Here we do not introduce the principle of the traditional mirror debugging method. We mainly introduce the online focusing method of the CINOGY camera beam analyzer:

Please see the basic principle diagram of the collimator online focusing below:

In the on-line focusing of the collimator, the debugging method of the beam analyzer is mainly to use the on-line measurement of the spot size (ellipticity) of the beam analyzer, and since the size of the spot size has no relationship with the power, the measurement process is performed. And the operation is very simple. It is only necessary to adjust the distance between the fiber and the lens at the corresponding measuring distance so that the measured spot size is the same (for example, the measuring distance is 60 mm and the spot size is adjusted to 350 um), so that the loss is the lowest (less than 0.2 dB).

1. The software interface is simple and clear, easy to operate, and measures the spot size, ellipticity, beam position and other parameters in real time.

1. Save new staff training time and cost

2.1~2 days, greatly reducing the training time and cost for new employees.

3. Low cost - tax-included price as low as 20,000 RMB

4.CINOGY camera beam analyzer with tax price as low as 20,000 RMB (CMOS-1202 camera), its high cost performance is one of the important reasons for customers to use in batch production and automation systems.

5. Can be replaced with a slit beam analyzer with higher accuracy and response speed

6.A. Support secondary development---automation equipment integration

B. Camera beam analyzer analysis software RayCi supports secondary development, we can provide the corresponding software secondary development kit (SDK), so that customers can easily use the beam analyzer for system integration (such as integration into automation equipment) .
