Spectrogon红外滤光片的清洁和处理

滤光片的清洁和处理
SPECTROGON的滤光片的设计和制造可以承受严格的环境条件。但是，所有光学组件在搬运，保养和存放时都应特别考虑。所有SPECTROGON滤光片在出厂前均经过检查，并包装在特殊的保护性容器中。收货后无需额外清洁。

应避免对滤光片进行所有不必要的处理，以减少损坏的可能性。滤光片应由边缘处理。尽量避免处理滤光片表面。地，所有与滤光片的工作应在清洁的环境中进行，例如。层流柜或类似产品。理想情况下，应采用正常的无尘室程序。

如果滤光片表面脏污或弄脏，则可以将其清洗。在大多数正常情况下，可以根据以下步骤，用温水和温和的清洁剂清洁滤光片，前提是基材和/或涂层不溶于水：

a、用水/中性清洁剂溶液润湿镜头清洁纸，然后轻轻擦拭滤镜表面，直到表面清洁为止。

b、用蒸馏水冲洗，然后立即用镜头清洁纸擦干。

如果将滤光片置于空气中干燥，则可能会出现不可逆转的的干燥污渍。

不能使用水/温和清洁剂方法清洗的杂质，或者如果基材/涂层可溶于水的杂质，可以使用异丙醇或丙酮清洗。

用溶剂润湿镜头清洁纸并擦拭表面几次，直到表面清洁为止。之后，立即用干燥的镜头清洁纸擦干。

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.
