Frequently Asked Questions
Image quality filters are designed for applications requiring high resolution and minimal optical distortion, such as astronomy and imaging systems. These filters use high-quality optical substrates that are polished to tight flatness and parallelism tolerances and typically include anti-reflective coatings to reduce ghosting and maximize throughput.
Commercial quality filters may offer the same spectral performance but are intended for instrument-based applications where imaging resolution is not the primary requirement.
Optical filters should be cleaned periodically to remove dust, fingerprints, or contaminants that may affect performance. In most environments, cleaning every three months is sufficient, although more frequent cleaning may be required in dusty or high-use conditions.
Cleaning can be performed using acetone, methanol, or alcohol applied to a soft, lint-free tissue, using a gentle circular motion.
Yes. Prolonged exposure to high humidity and rapid temperature changes should be avoided. To reduce the risk of thermal shock, we recommend a maximum operating temperature of 70°C and a maximum temperature change of 5°C per minute unless otherwise specified.
Yes. Andover Corporation maintains in-house fabrication capabilities that allow filters to be customized in size, shape, and configuration to meet specific application requirements.
The center wavelength of an interference filter shifts with changes in ambient temperature. Providing the operating temperature allows us to design the filter so that its spectral performance aligns with your application conditions.
Most standard products ship within two to three business days from receipt of order. Lead times for custom or semi-custom products vary based on specifications and production requirements.
