Supports slit scanning and CCD/CMOS camera measurement methods, automatically identifying the spot size of the 1/e² energy distribution, calculating divergence angles (full angle / half angle) and ellipticity (accuracy ≥ 90%), and intuitively assessing collimation performance.

Agilent 8163B optical wave test system: 

With a resolution of 0.001dB and support for C/L band scanning, it accurately measures insertion loss (≤0.3dB), return loss (≥50dB for PC interface), and polarization-dependent loss (≤0.1dB).

Schmidt + Haensch FVA-3100 polarization analyzer: 

With a wavelength range of 1260-1650nm, it specializes in detecting polarization-dependent loss to ensure the polarization stability of single-mode transmission.

Laser power meter: 

Compatible with different power levels, it uses the power test method to measure the device's transmission rate and accurately calculate the proportion of light energy loss.

III. Mechanical and Structural Precision Testing Equipment

Veeco NT9100 white light interferometer: 

With a three-dimensional end face morphology analysis accuracy of 0.01μm, it can detect geometric parameters such as the fiber end face curvature radius (10-25mm) and vertex offset (≤50μm).

EXFO FTB-500 optical time-domain reflectometer: 

With a dynamic range of 45dB, it is used to measure the fiber attenuation coefficient and fault location, verifying the reliability of the fiber and collimator connection.

Precision rotating fixture and observation screen: 

The fixture supports 360° rotation, and in combination with a remote observation screen, it calculates the pointing angle by measuring the beam offset radius, evaluating the coaxiality of the optical axis and the mechanical center axis.
