FAQs
Which wavelengths fit pulse oximetry?
Oximeters commonly use a pair of wavelengths around the 880–910nm region; device teams select exact pairs based on detector response and optical stack.
Do you have consistent electrical characteristics across wavelengths?
Yes. The 880–910nm parts share similar electrical characteristics and are designed for interchangeability in many drive circuits.
What about reliability data?
Contact sales for available reliability summaries and to discuss test data needed for your design review.
