IRDiO Series
IRDiO is based on TD (Time-Domain) OCT technology utilizing a Michelson interferometer. By leveraging the unique characteristics of this interferometer, it can not only measure reflection loss (RL) with high sensitivity but also simultaneously acquire distance information up to the point where reflection occurs. Since its launch in 2016, the OCCR series has been recognized as a long-selling product for Micro crack checking. A new feature, “Insertion Loss (IL) Measurement,” has now been added. This all-in-one tool measures three parameters—IL (Insertion Loss), RL (Retern Loss), and Micro Crack detection (Detect)—with just one connector connection and a single click.IRDiO is highly effective for optical characteristic inspection of silicon photonics (SiPh) devices and chip-level evaluation during development. Its extremely low second peak (noise peak) and clear measurement waveforms make it easy to distinguish the real peak, ensuring accurate evaluation results. This characteristic enables stable data acquisition even for SiPh products with complex optical circuits.
