Can you make custom large-format filters up to 450 mm?
At KUPO Optics, we frequently get asked: 'Can you make custom large-format filters up to 450 mm?' The answer is a resounding yes! Our advanced production capabilities and innovative equipment make us a leader in manufacturing large, high-performance optical filters.
How Do We Make Large Custom Filters?Our state-of-the-art coating chambers stand 1.7 meters tall and 1.5 meters in diameter, featuring cutting-edge Ion Assisted Deposition (IAD) technology. This allows us to apply dense, uniform, and highly durable coatings, even on very large glass substrates. Thanks to the unique design of planetary rotating trays, each filter receives a perfectly even coating, meeting our tightest optical specifications.
Precision Cutting and Flexible Customization
With both linear and laser cutting equipment on-site, we can shape filters from glass plates up to 450 mm in diameter — even in unique or custom geometries. This means we can tailor filters exactly to your application's requirements, whether you need round, square, or special shapes.
Ultra-Clean Manufacturing Environment
All processing steps take place in our 2000 square meter cleanroom. This ultra-clean environment minimizes contamination, ensuring your filters meet the highest standards of optical performance.
Stringent Optical Inspection
Every large-format filter undergoes comprehensive inspection using high-precision spectrometers and surface quality assessment. We verify each product's transmission, reflectance, and surface precision before it leaves our facility.
