Hi @Ben-El,
We haven’t done it internally, so you’re in unknown territory here. A few requirements would be:
- A 5mm LED that sources 488nm (example)
- A 5mm PD that sinks 510nm (example)
- Optical filters to prevent leakage of the source LED into the PD
After a quick google search, I think the hardest part is going to be finding optical filters, 3. Ideally the optical filter(s) are flexible, and could be placed between the vial and vial holder.
However, most optical filters are both i) expensive, and ii) not flexible.
Maybe others have some ideas?
