Glass & Optics Preparation

The Objective

What are we trying to achieve?

Ensure zero-defect visual clarity and prevent microscopic scratches on delicate optical coatings.

Invisible binders in standard wipes cause streaking, while rough fibers cause micro-scratches that ruin expensive optics.

Common Challenges

Types of Contamination

✕ Fingerprints ✕ Oil smudges ✕ Dust particles ✕ Chemical residue ✕ Outgassing film

SOP

Standard Cleaning Procedure

STEP 1

Dry Dust

Gently blow off large particulate with ionized air to prevent dragging grit across the lens.

STEP 2

Apply Cleaner

Apply optical cleaner directly to the wipe, never to the optic.

STEP 3

The "Drop and Drag"

For delicate lenses, lay the saturated wipe on the lens and drag it slowly across without applying downward pressure.

STEP 4

Final Polish

Use a dry cleanroom wipe to gently buff away any remaining solvent flash.

✓

Best Practices

✓ Handle optics by the edges
✓ Use the "Drop and Drag" technique
✓ Inspect under bright light
✓ Use laundered polyester

✕

Avoid These Mistakes

✕ Applying pressure
✕ Spraying cleaner on the glass
✕ Using paper products (scratches)
✕ Circular buffing
