Cleaning the Aesthetix

Cleaning the Aesthetix sensor

This page explains how to clean the Aesthetix sensor optics and contact surfaces to maintain reliable measurements while avoiding damage to the instrument or samples.

Safety and general rules

  • Do not attempt to open the sensor housing.
  • Always stop measurements in the software before cleaning.
  • Never use household cleaners, abrasive materials or unapproved solvents on any part of the sensor or adaptors.

Cleaning the sensor lenses and optical window

The optical window and internal lenses are precision components and must only be cleaned using a dedicated lens cleaning kit (e.g. camera/optical lens kit including blower, lens brush and lens tissues or cloth).

  1. Inspect the window under good lighting for dust, fingerprints or smears.
  2. Use the blower from the lens kit to remove loose dust; do not use your breath.
  3. If particles remain, use the soft lens brush from the kit with very light strokes.
  4. For fingerprints or smears, apply a small amount of lens cleaning fluid to a lens tissue/microfiber from the kit (never directly to the window).
  5. Wipe the window gently in straight lines, then dry immediately with a fresh lens tissue.

Do not:

  • Use paper towels, standard cloths or cotton buds.
  • Press hard, scrub in circles or reuse dirty tissues.
  • Spray or drip liquid directly onto the sensor.
Optic cleaning may result in measurement issues if not performed correctly. Contact Rhopoint Service if in any doubt- if possible return instrument for factory or service centre cleaning

Cleaning adaptors and contact surfaces

  1. Remove the adaptor from the sensor.
  2. Wipe the outer contact faces and rubber feet with a clean, lint‑free cloth slightly dampened with water or mild detergent if required; then dry thoroughly.
  3. Keep the measurement opening free from paint, dust and fibres; if needed, use the blower from the lens kit around the aperture (avoiding direct contact with the optics).

Avoid solvents that could attack rubber or plastic parts, and ensure all surfaces are completely dry before re‑attaching the adaptor.

Good practice to prevent contamination

  • Store the sensor and adaptors in their case when not in use.
  • Avoid placing the instrument face‑down on dusty or painted surfaces.
  • Do not measure on uncured or heavily contaminated coatings.
