At KUPO Optics, we pride ourselves on our state-of-the-art manufacturing facility, specifically designed to meet the highest standards in optical filter production. Our commitment to excellence is evident in our expansive 2000 square meter cleanroom, which ensures an ultra-pure environment that is crucial for the flawless creation of our premium filters. This meticulous attention to environmental control virtually eliminates the risk of particle contamination, a common cause of coating failure in lesser quality filters.
 
Our production process is further enhanced by advanced coating chambers equipped with Ion Assistant Deposition (IAD) technology, ensuring that our filters boast uniform and durable coatings. We understand that precision is paramount in our industry, which is why every stage from cleaning to cutting and inspection is executed with meticulous care, utilizing the finest instruments and techniques available. We take great pride in delivering products that not only meet but exceed the rigorous demands of our customers.
 

Cleanroom

 
Our expansive 2000 square meter cleanroom is the cornerstone of KUPO Optics' ability to manufacture filters of the highest quality. Within this controlled environment, we meticulously manage air quality to prevent the tiniest of particles from affecting our filters. This is integral to ensuring the integrity and performance of our coatings and is a testament to our unwavering commitment to excellence.

Spectrometer

Quality assurance is at the core of our production, and our spectrometers are central to this purpose. By meticulously scanning each coated filter, we ensure that every product aligns with the required optical specifications. This double-check system, both before stocking and again prior to shipment, reinforces our commitment to delivering impeccably accurate filters.
