LD Chip Tester

LD2900MTB

Overview

This device is an LD test system that automatically measures and sorts the electrical and optical characteristics of long-wavelength (for optical communication) laser diodes in the bare chip state at high speed.

LD2900MTB measures the measurement items of "IL measurement (FRONT / BACK)", "IV measurement", "Ir, Vr measurement", and "wavelength measurement" at a single temperature (-40 ° C to 95 ° C).

Customers can add necessary items such as "OCR function", "RF high frequency superimposition", and "EA measurement" as options.

Measuring Holder

・ Index turntable method (1 unit / temperature)

・ 2 stations / TT type

Position 1: Supply, storage, gaugeing position

Position 2: Probing, measurement position

(IL measurement (FRONT / BACK), IV measurement, Ir, Vr measurement, wavelength measurement)

・ Measurement holder: 2 holders

Temperature Range

・-40℃~95℃

Chamber test room / Supply / Discharge pass box

The measurement room has a chamber structure, and during the -40 ° C test, the inside of the tank is filled with dry air or N2 gas to prevent dew condensation. The grip ring can be taken in and out of the measurement room via the pass boxes on the left and right.

Contact Method

・ Needle type probe contacts top electrode, bottom electrode contacts by measurement stage
