The spectrum is as follows:
If you are buying optical products made of glass materials such as filters/attenuators/reflectors/splitters, please pay special attention to:
1. Avoid storing the filter in a humid, high temperature environment.
2. Avoid hard objects scratching the filter surface and crushing by heavy objects.
3. Put on finger gloves or rubber gloves. If you do not have one, wash and dry your hands before removing the lens. Place the lens lightly on the lens paper, do not place it on a rough or hard surface to avoid damage. When stained with dust or fingerprints, soak a small amount of solvent such as industrial alcohol or ethanol with a cotton swab or cotton ball and gently wipe. Do not use force. Slowly wipe the entire lens in one direction at a time. Avoid rubbing back and forth. Wait for the solvent to cool. After drying, put it in the appropriate position to use.
4, the use of color filter temperature should not exceed 80 degrees. If you need to use under high temperature conditions, please explain to the seller that only tempered filters can be used at high temperatures, but it is best not to exceed 250 degrees to avoid damage to the filter. .
5, the filter in the process of use, should avoid the sudden rise and fall of temperature. If the temperature difference is too large, the filter will fail. Please proceed with caution.
6, the combination of filter and instrument or device: if the instrument or device is threaded, the filter can be installed on the corresponding ring, and then screwed to the equipment; If there are no threads and only structural parts, you can use AB glue or UV glue to glue the filter to it. If that doesn't work, you can talk to customer service and provide guidance.
