DLP3010: Reflection efficiency of DLP3010

Hiroyasu Tazawa1

Part Number: DLP3010

Hi,

Let me talk about reflection efficiency of DLP3010

We think it can be calculated by the following formula.

DMD reflection efficiency = Window transmittance ^ 2 × mirror reflectivity × array diffraction efficiency × array filter

We understand Window transmittance is 97% from the data sheet (Window transmittance, both surface and glass)

but We could not find other parameters.
Could you tell me the following parameters for the calculation.

-Reflectance of mirror
-Array diffraction efficiency
-Array file factor

Best Regards

Dear Kyle

Thank you !

I did not get value of Array diffraction efficiency.
Could you tell me this value ?

Hello Hiroyasu,

I am looking at what information we have to share. Could you please confirm why you are looking for this information. Diffraction efficiency can change with system variables.

Thanks,
Kyle

Dear Kyle

I asked my customer.
They wanted to know DMD reflection efficiency.
We already know that. then It should be closed.

Thank you for your support !

Best Regards
Hiroyasu
