Original question:

850nm peak spectrum sensitivity

OPT101: newer alternatives?

Part Number: OPT101
Other Parts Discussed in Thread: OPT3002

Hello team,

I saw a previous thread about any newer device that has high sensibility around the 850nm wavelength and wanted to double check again.

They complain that the device is quite old, their specs needed the most are:

- ability to read around 850nm

- integration time a lot less than 1ms

- product should be resistant to sulfuration

Please let me know if we have any update.

Thank you and best regards,

Adrian

    Hi Adrian,

    We have newer parts (OPT300x line). OPT3002 is the only one that has a response at 850nm.

    Two potential issues you may have with it given your requirements are that it is wide spectrum response so please check if that is okay. Also response time is 100ms or 800ms so it cannot do 1ms or less.

    Currently, only the older analog output parts can to the faster response times.

    Best,

    Alex
