Compensation Actually Paid vs. Total Shareholder Return [Text Block] | Over the three-year period from 2020 to 2022, our TSR trended in a manner similar to the Peer Group TS R . The increase in the Company’s TSR lagged our peers in 2020, and in 2021 our TSR showed a modest increase while the Peer Group TSR remained relatively flat. Our 2022 TSR performance was lower than that of our peers, which contributed to a significant decrease in “Compensation Actually Paid” to our CEO and NEOs in 2022. For 2020 to 2021, our TSR and net income showed a slight positive correlation to “Compensation Actually Paid”, which showed a larger increase because of the improvement in our financial outlook that drove a large increase in the yearend fair value of our PSUs. For 2021 to 2022, our TSR and net income showed a strong positive correlation to “Compensation Actually Paid” due to our emphasis on performance-based pay that ties our executive’s compensation to our stock price and financial performance. For 2020 to 2021, Core Illumina Revenue showed a positive correlation to “Compensation Actually Paid”, but an inverse correlation for 2021 to 2022. |  |
