LD Chip Tester
This device is an LD test system that automatically measures and sorts the electrical and optical characteristics of a bare-chip laser diode at high speed. It is compatible with various LDs and has a large number of long wavelength and short wavelength deliveries.
We have a track record of supporting COS, COC, VCSEL, etc.
Basically, the measurement items are "IL / IV measurement" and "wavelength measurement".
Optional "FFPV, H measurement" "RF high frequency superimposition" "EA measurement" "Polarization ratio measurement" "High-speed pulse measurement"
The customer can add required items as option.
Bare chip LD, COS, COC, VCSEL, top 2 electrodes, flip chip, etc.
