Astronomy filters are specialized optical components designed to enhance the observation and imaging of celestial objects by isolating specific wavelengths of astronomical interest while rejecting unwanted light. These precision-engineered filters enable researchers and astronomers to study specific features of stars, nebulae, galaxies and other astronomical phenomena with exceptional clarity.

Each astronomy filter is characterized by several critical parameters:

• Spectral Range: The specific wavelength band optimized for different astronomical targets
• Image Quality: Ultra-precise polishing and coating for minimal wavefront distortion
• Environmental Stability: Designed to maintain performance in varying temperatures and conditions
• System Compatibility: Engineered to work with both visual and electronic imaging systems

Andover Corporation manufactures a comprehensive range of astronomy filters, from standard photometric systems like UBVRI (both Johnson/Bessell and Kron/Cousins sets) to specialized filters for solar observation and infrared astronomy. Using state-of-the-art thin film technology and premium optical materials, we deliver filters that meet the exacting demands of modern astronomical research, whether for ground-based observatories or space-borne instruments.
