5. Istruzioni per l'uso
The Dioche 4mm C Mount Lens features manual focus and adjustable aperture. Proper adjustment is crucial for achieving clear and well-exposed images.
5.1. Regolazione della messa a fuoco
- Accensione della fotocamera: Power on your industrial camera and access its live view or monitoring interface.
- Rotate Focus Ring: Locate the focus ring on the lens (often marked with "NEAR" and "FAR" or infinity symbol). Gently rotate this ring to adjust the focus until the image appears sharp on your monitor.
- Sintonizzare: For critical focus, zoom in on a specific area of interest in your camera's live view and make small adjustments to the focus ring.
5.2. Adjusting Aperture
The aperture controls the amount of light entering the lens and affects the depth of field.
- Locate Aperture Ring: Find the aperture ring on the lens, typically marked with F-numbers (e.g., F1.8, F2.8, F4, F8, F16).
- Rotate for Desired Brightness/Depth of Field:
- Rotating towards smaller F-numbers (e.g., F1.8) opens the aperture, allowing more light in and creating a shallower depth of field (more background blur).
- Rotating towards larger F-numbers (e.g., F16) closes the aperture, allowing less light in and creating a deeper depth of field (more of the scene in focus).
- Monitor Image: Observe the image on your camera's monitor to achieve the desired brightness and depth of field for your application.

6. Manutenzione
Una corretta manutenzione garantisce la longevità e le prestazioni ottimali delle lenti.
- Pulizia della lente: Use a soft, lint-free microfiber cloth specifically designed for optics to clean the lens elements. For stubborn smudges, use a small amount of lens cleaning solution applied to the cloth, not directly to the lens.
- Rimozione della polvere: Utilizzare un pennello a soffietto per rimuovere le particelle di polvere dalla superficie della lente prima di pulirla. Evitare l'uso di aria compressa, che può danneggiare i rivestimenti.
- Magazzinaggio: When not in use, always attach the front and rear lens caps to protect the lens elements. Store the lens in a dry, cool place, away from direct sunlight and extreme temperatures.
- Evitare l'impatto: Handle the lens with care to prevent drops or impacts, which can damage the optical elements or mechanical components.
