Instructions for using ArmD™ MIR fibers

1. Handling Silver Halide Fibers:

Avoid touching the bare core/cladding; use dry, soft polymer, or paper.

Never touch the surfaces at the ends of the fibers to prevent laser damage.

Protect fibers from visible and UV radiation, including luminescent light.

2. Storage:

Maintain optical properties by storing in a dry, dark environment (e.g., loose, black polymer tube).

3. Protection During Storage:

Cover fiber tips with opaque caps to shield against contamination and UV/visible radiation.

Remove caps just before use, ideally in red light.

4. Preventing Deformation:

Ensure a minimum bending radius of 100 times the fiber diameter to prevent deformation. 

5. Connecting to Laser Beam:

Begin at low intensity and check spot size before increasing laser power.

Do not place the fiber too close to the irradiated area during intense radiation.

6. Preventing Overheating:

Use cooling measures when cables are employed for laser cutting or drilling.

Prevent fiber tips from melting (melting point: approx. 412 °C).

7. Smoothing Fiber Tip:

Use the sharpened edge of a knife, scalpel, or diamond knife (preferably from a dielectric material).

A microtome is recommended for optimum results; cut the thin part of the fiber slowly after the first cut.
