Handling and cleaning instructions
Lensed fiber arays are extremely fragile due to the exposed microfabricated lenses, so before you start using them please observe the following FAQ on the topics of handling, storage, and cleaning.
Frequently Asked Questions (FAQ)
How are lensed fiber arrays shipped to me safely?
Our lensed fiber arrays (LFAs) are packaged in boxes with foam inserts. The foam inserts securely hold the fibers and the lid in place. The lid is protected by a dedicated enclosure, which can be reused for safe storage of the LFA. Make sure to keep the box and foam inserts at a safe distance from ESD sensitive equipment.
How do I safely unpack and handle a lensed fiber array?
Lensed fiber arrays should be handled with a lot more care than regular fiber arrays, because the microfabricated lenses at the edge of the lid are very fragile. Please observe the following instructions.
- Put on protective gloves and keep a pair of tweezers and an 1.5 mm (0.059″) allen key at hand.
- Remove the tape from the foamed insert of the box.
- Take the plastic enclosure containing the lid of the LFA out of the foam and open it.
- While gently holding down the LFA at the epoxy just behind the lid, loosen the bolt of the rotating clamp using the allen key.
- Open the rotating clamp and the black foam fiber holder and gently lift the LFA out of the enclosure, avoiding any contact with the exposed lenses.
- Take the fiber connectors out of the foam.
- You can reuse the plastic enclosure for storing the LFA after use. Please closely observe the correct position of the lid relative to the rotating clamp.
How do I clean a lensed fiber array?
Don’t ever touch the lenses or apply sonication! Cleaning of the lenses is best attempted by applying gentle compressed air or nitrogen, in a direction on axis with the lenses. If contaminations remain you can dip the lensed fiber array in isopropyl alcohol (IPA), limiting the exposure to a maximum of 10 minutes and avoiding any physical contact with the lenses. You can dry the unit with gentle on-axis exposure to compressed air or nitrogen.
