3. セットアップとインストール

Proper installation of the F-Theta lens is crucial for optimal performance and safety. Always wear appropriate personal protective equipment, including laser safety glasses, when working with laser systems.

1. 準備： Ensure the laser marking machine is powered off and disconnected from the power source.
2. 既存のレンズを削除します（該当する場合）： Carefully unscrew and remove any existing lens from the galvanometer scanner head.
3. Install F-Theta Lens: Gently screw the Cloudray F-Theta Lens into the M85x1 threaded port of the galvanometer scanner head. Ensure it is tightened securely but not excessively to prevent galling of the threads.
4. インストールの確認: Confirm the lens is seated correctly and stable.

4. 操作手順

The F-Theta lens works in conjunction with galvanometer mirrors to precisely direct and focus the laser beam across the marking area. Understanding the focal length and field size is essential for accurate operation.

1. 焦点距離調整: When changing the F-Theta lens size, it is necessary to adjust the focal length in your laser software. This ensures the laser beam is correctly focused on the material surface across the entire scanning field.
2. ソフトウェアキャリブレーション: Utilize your laser marking software (e.g., Lightburn for Mac, EZCAD) to calibrate the new lens. This typically involves setting the correct field size and adjusting galvanometer scales to ensure accurate marking dimensions.
3. Test Marking: Before final production, perform test markings on scrap material to verify focus and accuracy. Adjust software settings as needed.

5. メンテナンス

Regular maintenance ensures the longevity and performance of your F-Theta lens.

• クリーニング： Keep the lens surfaces clean and free from dust, debris, and fingerprints. Use only specialized optical cleaning solutions and lint-free wipes designed for laser optics. Avoid abrasive materials or harsh chemicals.
• ストレージ： When not in use, store the lens in its protective casing or a clean, dry environment to prevent damage and contamination.
• 検査： Periodically inspect the lens for any signs of damage, scratches, or coating degradation. Replace the lens if significant damage is observed to maintain laser performance and safety.

6。 トラブルシューティング

This section addresses common issues you might encounter with your F-Theta lens.

• Poor Focus or Inconsistent Marking:
  • Verify that the focal length in your laser software matches the specifications of the installed lens.
  • レンズがきれいで障害物がないことを確認してください。
  • Recalibrate the lens within your laser software, paying attention to field size and galvanometer settings.
• Lens Thread Galling:
  • When installing or removing the lens, tighten it only until snug. Avoid overtightening, which can cause the threads to seize or "gall."
  • If galling occurs, carefully apply a small amount of anti-seize compound or optical-grade lubricant to the threads (avoiding optical surfaces) and attempt to loosen gently.
• Reduced Laser Power or Transmittance:
  • Inspect the lens for any damage, scratches, or excessive dust/debris. Clean the lens as per maintenance instructions.
  • Ensure the laser source is operating correctly and its power output is within expected parameters.
