OPT8241-CDK-EVM: Bandpass filter

leon park

Part Number: OPT8241-CDK-EVM

What is the transmission curve for the IR filter on the detector? If I would like to use other wavelengths, is the filter applied a thin film that can be easily removed? We may need to go down to 790nm.

Hi Leon,

The transmission curve is present in the datasheet of OPT8241, Figure 5.

Thank you Subhash. Are you able to tell me about the construction of the filter?

Leon,

The filter construction is proprietary. We would not be able to reveal details about the filter besides the transmission characteristics.

Subhash
