Ultra-narrow H-beta filter designed for maximum contrast and background suppression, ideal for imaging under light-polluted skies or during bright moon phases.
Balanced H-beta filter that offers strong contrast while maintaining higher signal throughput, suitable for a wide range of imaging conditions.
For observatories, research programs, or specialized imaging systems, Chroma develops custom narrowband filters with non-standard center wavelengths, bandwidths, sizes, or coating requirements.
Astronomy filters must maintain spectral accuracy across temperature changes, humidity, and years of use. Chroma’s hard-sputtered coatings are engineered for durability and stability, helping ensure consistent performance for long-term imaging projects and scientific studies.
As an ISO-certified manufacturer, we adhere to strict quality assurance procedures and stand behind this commitment with an industry-leading warranty—our assurance of long-term stability and performance.
