Spectrogon紅外濾光片的清潔和處理

濾光片的清潔和處理
SPECTROGON的濾光片的設計和制造可以承受嚴格的環境條件。但是，所有光學組件在搬運，保養和存放時都應特別考慮。所有SPECTROGON濾光片在出廠前均經過檢查，并包裝在特殊的保護性容器中。收貨后無需額外清潔。

應避免對濾光片進行所有不必要的處理，以減少損壞的可能性。濾光片應由邊緣處理。盡量避免處理濾光片表面。地，所有與濾光片的工作應在清潔的環境中進行，例如。層流柜或類似產品。理想情況下，應采用正常的無塵室程序。

如果濾光片表面臟污或弄臟，則可以將其清洗。在大多數正常情況下，可以根據以下步驟，用溫水和溫和的清潔劑清潔濾光片，前提是基材和/或涂層不溶于水：

a、用水/中性清潔劑溶液潤濕鏡頭清潔紙，然后輕輕擦拭濾鏡表面，直到表面清潔為止。

b、用蒸餾水沖洗，然后立即用鏡頭清潔紙擦干。

如果將濾光片置于空氣中干燥，則可能會出現不可逆轉的的干燥污漬。

不能使用水/溫和清潔劑方法清洗的雜質，或者如果基材/涂層可溶于水的雜質，可以使用異丙醇或丙酮清洗。

用溶劑潤濕鏡頭清潔紙并擦拭表面幾次，直到表面清潔為止。之后，立即用干燥的鏡頭清潔紙擦干。

Cleaning and handling of filters
SPECTROGON’s filters are designed and manufactured to withstand the most stringent environmental conditions. However, all optical components deserve special consideration in handling, caring and storage. All SPECTROGON filters are inspected prior to shipment and packaged in special protective containers. No extra cleaning should be necessary upon receipt.

All unnecessary handling of filters should be avoided to reduce the possibility of damage. The filters should be handled by the edges. Try to avoid handling the filter surfaces. Preferably, all work with the filters should be done in a clean environment, eg. laminar flow cabinet or similar. Ideally, normal clean room procedures should be applied.

If a filter surface is dirty or stained, it can possibly be cleaned. In most normal cases filters may be cleaned with a solution of lukewarm water and mild detergent, providing the substrate and/or the coating is not water soluble, according to the following procedure:

a、Wet a lens cleaning tissue with water/mild detergent solution and wipe the filter surface gently until the surface is clean.

b 、Rinse off with distilled water and immediately wipe dry with a lens cleaning tissue.

If the filter is left to dry in air permanent drying stains may appear.

Impurities that are not cleaned with the water/mild detergent method or if the substrate/coating is soluble in water, isopropyl alcohol or acetone cleaning can be used.

Wet a lens cleaning tissue with the solvent and trail wipe the surface several times until the surface is clean.
Thereafter, immediately wipe dry with a dry lens cleaning tissue.
