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.
