How Should I Clean My Optical Filters?
One of the most common questions that customers ask the staff of Chroma Technology is “How should I clean my filters?”
This is an important task for maintaining their optimal performance. Incorrect cleaning or handling can risk damaging your filters so it’s critical to do it right.
Chroma has a detailed cleaning guide on the company website. But first, let’s start with the essential tools you’ll need for cleaning and why they are necessary:
- Nitrile Gloves: Protect filters from oils and contaminants from your hands.
- Reagent-Grade, Anhydrous Ethyl Alcohol: Ideal for removing contaminants without leaving residue.
- Lint-Free Task Wipes: Prevent the introduction of new particles.
- Bulb Puffer or Filtered Compressed Air: Safely removes loose dust and debris.
Again, for the complete guide to cleaning and handling your optical filters, check out Chroma’s detailed instructions.
