Part Number: OPT8241

Hi,

Let me ask you a question about the optical passband.

Is it possible to modify the band from 850nm to 940nm?

That is to say, can we use 940nm IR for OPT8241?

Thank you for your support.

Hi Takumi,

It is possible in principle to have an optical filter which works at 940nm light wavelength. However, TI doesn't have a variant which supports this wavelength of light.

Hi Subhash-san,

Thank you for your reply.

The application is for in door use but the customer would like "invisible" light.

850nm light is visible for us..
