Usage

1. Download one of the compatible apps if you haven't done so already
2. Crucial Set the diffuser type to "Diffuser Accessory" in the app's settings
3. Center the accessory exactly over the front camera using the placement help

Attachment

1. Clean the camera before each appliance (see cleaning instructions)
2. Ensure a snug fit* (e.g. by removing a protective case)

* If your device's camera is near the screen's edge, the diffuser may not fully cover the screen, allowing a small amount of light to enter from the back. This minimal light ingress can be disregarded, as it won't impact the measurements. However, it's crucial to ensure the accessory lies flat on the screen.

Storage

For maximum longevity, store the Diffuser & Cosine Corrector accessory within its bag at room temperature whenever not in use. Never disassemble the diffuser accessory.

Cleaning Instructions

To ensure accurate measurements, it's essential to keep both the camera and the accessory clean, as dirt and dust particles can affect performance.

Camera

Before attaching the diffuser accessory, remove any dirt (e.g. fingerprints) from the area around the front camera using a lint-free cloth. For stubborn dirt, lightly dampen the cloth with a screen cleaning solution or isopropyl alcohol.

Diffuser Accessory

If dust or particles accumulate on the diffuser (white disk), use oil-free compressed air to safely remove them. For greasy dirt, clean it with a lint-free cloth and isopropyl alcohol.
