Optical filters
Optical Filter Manufacturing and Customization
Optical filters are precision components engineered to selectively transmit, reflect, or absorb specific wavelengths of light across the electromagnetic spectrum. At Star Optics, we specialize in manufacturing high-performance optical filters utilizing advanced thin-film coating technologies, including ion-beam sputtering (IBS), plasma-assisted deposition, and magnetron sputtering processes.
Our manufacturing capabilities cover the full spectral range from deep UV (200nm) to far infrared (15μm), with precise control over transmission characteristics, edge steepness, and blocking depth. Each filter undergoes rigorous spectrophotometric testing using calibrated instruments to ensure compliance with customer specifications. Whether you require standard catalog products or fully customized solutions, our engineering team provides comprehensive support from optical design through volume production.
Types of Optical Filters We Provide
We deliver off-the-shelf items and fully customized filters tailored in wavelength, bandwidth, OD blocking, substrate, and coating architecture — from prototype runs to volume production.
Why Choose Star Optics
Engineering-First Approach
We evaluate your light source, detector, and environmental constraints before any design work begins, ensuring the filter is fully compatible with your optical system and reducing unnecessary redesign cycles.
Rapid Prototyping
With stocked substrates and dedicated coating capacity for pilot runs, we can deliver custom samples quickly—allowing your R&D team to test, refine, and iterate without delays.
Reliable Quality Assurance
Each filter undergoes comprehensive spectral measurement and essential environmental testing, accompanied by full data reports to guarantee performance consistency across every batch.
Cost and Supply Stability
Optimized coating processes and efficient chamber utilization help reduce production costs, while our secure material supply chain supports dependable delivery from prototypes to full-scale manufacturing.
How to Order Custom Optical Filters
