Andover Optical Filters
Precision wavelength selection from 193nm to 15μm
Precision Through Innovation
Optical solutions that push technological boundaries forward
Andover Corporation designs and manufactures high-performance optical filters and coatings for UV, visible, and infrared applications. Covering wavelengths from 193nm to 15µm, our filters deliver precise wavelength control, superior durability, and industry-leading optical quality.
With advanced thin-film coating technologies and a vertically integrated manufacturing process, we provide both custom-engineered and high-volume optical filter solutions. Every filter is 100% inspected and verified for performance, supporting demanding industries such as aerospace, defense, medical imaging, spectroscopy, and astronomy.
Our Optical Filter Categories:
- Bandpass Filters: Transmit specific wavelength ranges while blocking unwanted light for maximum signal clarity.
- Neutral Density (ND) Filters: Precisely control light attenuation and intensity for imaging and laser systems.
- Infrared (IR) Filters: Optimized for thermal imaging, spectroscopy, and laser applications.
- Ultraviolet (UV) Filters: – High-performance transmission for semiconductor lithography, analytical instrumentation, and UV laser systems.
- Edge Filters: Standard and steep-edge short-pass and long-pass filters designed for high-efficiency wavelength separation.
- Astronomy Filters: Precision filters for ground-based and space-based telescopes, ensuring accurate spectral isolation.
Whether you need a standard optical filter or a custom solution engineered to your specifications, Andover Corporation delivers exceptional optical performance, rapid turnaround times, and trusted customer support.
