Changing the measured optical filter frequency for a CO2 like sensor

Sensors
1

I am trying to find a sensor(like a CO2 sensor) that can measure or is already set up to measure a different frequency. The frequency that I am trying to measure is between 2900-3000. As I understand, that would require changing the Optical filter in a CO2 sensor to let through the correct frequency.

Is there a sensor that can already do this, would I have to get a custom sensor made or am I looking at the wrong type of sensor for this application?

Thank you for any help you can provide

Is Methane your target ?

no unfortunally not the target

Have a custom optical filter made for an existing CO2 NDIR sensor. Naturally that would require dismantling, modifying and recalibrating the sensor.

am I looking at the wrong type of sensor for this application?

Seems likely, but if you can’t reveal the application, you can’t expect a better answer.
