Module Tester Product Line

VCSEL EOL Tx & Rx combined tester is used to control the quality of the product and do the OQC checking before shipment. By checking the performance of the fully assembled module, we can filter out the defective products with abnormal power or bad image performance.

The Z height of the image sensor would change as the OIS XY moves to different positions. Thus, there’s the need to calibrate the sensor Z height per module to ensure its good image quality while capturing images dynamically. And the camera module should be calibrated under different postures.

This machine performs optical testing and calibration of the VCSEL and its corresponding photoreceptor (Tx/Rx Sensor). The detection range includes reflectivity detection, transmittance detection, and band interference detection. The technology covers optics, vision, and circuitry, ultimately achieving production process quality control for products.

VCSEL FOL tester is used to control the quality of the product during assembling. By checking the optical characteristics of each emitter on the VCSEL, we can filter out the defective products with dead emitters or having lower power performance.
