Storage Precautions for SAPPHIRE OPTICAL COMPONENTS

Storage Precautions for UltraOpto SAPPHIRE OPTICAL COMPONENTS (Sapphire Optical Components)

Technical Instructions

Sapphire optical components, with their high hardness, corrosion resistance, and wide band transmission characteristics, are widely used in high-end optical equipment. However, during storage, strict control over the environment and operation norms is still necessary to prevent performance degradation and ensure optical consistency after long-term storage.

I. Storage Environment Requirements

Temperature and Humidity Control

The storage environment should be kept at a constant temperature and humidity, with the temperature controlled between 18-25°C and the humidity maintained at 30%-50%. Sudden temperature changes should be avoided to prevent thermal stress on the components, and high humidity should be prevented to avoid surface condensation and mold growth.

Cleanliness Requirements

Components should be stored in a 1000-class clean room or a sealed clean cabinet, away from dust, oil, acid and alkali vapors, and other contaminants. They must not be stored in the same warehouse as organic solvents or corrosive chemicals to prevent surface corrosion.

Light and Radiation Protection

Components should be protected from long-term exposure to strong light, ultraviolet rays, or strong electromagnetic radiation. It is recommended to store them in light-proof sealed boxes to prevent the degradation of the optical performance of the sapphire substrate.

II. Packaging and Placement Standards

Packaging Method

Each component should be independently packaged in an anti-static dust-free bag. For large components, custom anti-static foam pads can be used for fixation to ensure no direct friction between the component and the packaging. Before packaging, the surface of the component should be purged with nitrogen to remove any residual dust.

Placement Requirements

Components should be placed horizontally and not stacked or compressed. The stacking height should not exceed three layers. Irregular components (such as prisms and light guides) should be fixed with special fixtures to prevent edge and corner damage or cracking.

III. Operation and Management Standards

Handling Guidelines

When handling components, wear anti-static gloves and dust-free clothing. Use a vacuum pen to lift the non-optical edge of the component. Direct contact with the optical surface is strictly prohibited to avoid contamination from fingerprints and sweat.

Regular Inspection and Maintenance

Conduct a random inspection of the stored components every quarter. Use a microscope to check for scratches and mold spots on the surface, and use an optical detector to re-measure the transmittance and surface flatness to ensure no performance degradation.

Inventory Management

Establish an inventory ledger and follow the "first in, first out" principle to avoid long-term accumulation of components. Components stored for more than 12 months should be thoroughly cleaned and tested for performance before being released from storage. Only those that pass the test can be put into use.
