Spectral response

Other Parts Discussed in Thread: OPT3002

Hi,

We're trying to use OPT3002 for measuring light intensity for a single wave length around ~900nm.

Problem is the spectral response around 900nm is varying (almost ~50%).

1. Why is the spectral response so variant around 900nm?

2. Is this some kind of measuring error?

3. Can we get a zoomed in spectral response? (855nm - 925nm)

Thanks,

Shlomi

Hi,

Will get back on this today,

Hi,

By varying do you mean between different OPT3002 devices or varying over time? What is the light source you are using in this test?

Hi,

I mean varying depends on the wavelength. Spectral response.. 900nm Vs 920nm for example.

Hi Shlomi,

Understood. Zooming in on the datasheet plot we can see that ~50% change going from ~920nm to 900nm is reflected in the plot so this sounds correct.

Best,

Alex
