OPT4001: Confirmation of Differential Impact of Same-Material Dustproof Film on ALS Component Itself

Part Number: OPT4001

CPN:14-100124     MPN: OPT4001YMNR

On the Amazon Amelia project, we found that after attaching the dustproof film, the test results for the following component shifted significantly. Please confirm with the original manufacturer why dustproof films made of the same material have such a large differential impact on the ALS component itself. The email below contains our internal verification results. Please help provide feedback and follow up. Thank you.

 

Background: After attaching the dustproof film to the Amelia ALS, under a fixed light source, the ALS test results showed two distinct ranges.

 

Sample #1 + Dustproof Film M1 / Sample #2 + Dustproof Film M2 – test results are as follows:

Through cross-validation, it has been confirmed that the bad test result discrepancy follows the ALS component itself.

Verification 1 (without film): Test OK.

Verification 2 (with film – abnormal test results): Test results are as follows:

Cross-validation 3 (swap dustproof films): The bad results moved with the ALS component.
