Frequently asked questions

To properly clean and maintain optical bandpass filters, follow these general guidelines:
Handling: Always hold the filter by its edges to avoid fingerprints and scratches.
Cleaning: If the filter becomes dirty, you can use a blower to blow away any loose dirt or debris. For smudges or fingerprints, use a soft, lint-free cloth and a small amount of optical-grade solvent (such as isopropyl alcohol or acetone). Rub gently in a circular motion.
Storage: Store filter in a clean, dry, and safe environment. It is best to keep them in their original boxes to prevent dust accumulation and accidental damage.
Avoid Contact: Minimize direct contact with filter surfaces. Touched filters may retain skin oils, making them difficult to clean, and may affect filter performance.
Regular Inspections: Check your filter regularly for any signs of damage or wear.
