KUPO Optics Manufacturing
KUPO Optics has built its facility around contamination control, repeatable coating performance, and careful inspection at every stage of production.
Our 2,000 square meter cleanroom, Ion Assistant Deposition coating chambers, substrate preparation workflow, custom cutting capability, and optical inspection process are all designed to support stable, high-quality filter manufacturing.
Instead of treating coating, handling, and verification as separate steps, the facility is organized as one connected process that helps reduce avoidable defects and improve consistency from the first substrate through final shipment.
Our cleanroom is a cornerstone of KUPO Optics' manufacturing capability. By controlling airborne particles throughout the process, we help protect coating quality, reduce contamination risk, and support the consistent surface condition needed for reliable optical performance.
Our coating chambers are approximately 1.7 meters high and 1.5 meters in diameter, and they are equipped with Ion Assistant Deposition technology. Combined with planetary rotating trays, this setup helps produce dense, durable coatings with uniform optical behavior across the substrate.
Before coating begins, substrates are processed through ultrasonic cleaning. This preparation step helps improve adhesion and reduces the chance that particles, residue, or surface contamination will affect the finished filter.
KUPO Optics supports both linear and laser cutting so filters can be produced in standard formats or custom shapes. This flexibility is especially useful for projects that require application-specific dimensions, tight fit-up, or fabrication from large 450 mm diameter plates.
Spectral verification is part of KUPO Optics' quality assurance process. By measuring coated filters against their required optical targets, we can confirm that transmission and blocking behavior align with specification before products are stocked and again before shipment.
Surface inspection helps confirm that finished filters meet KUPO Optics' scratch-and-dig quality requirements. Dedicated inspection tools make it easier to identify cosmetic or handling-related defects before a product reaches the customer.
KUPO Optics focuses on building filter quality through controlled production conditions, careful handling, and repeatable verification rather than relying on a single process step alone. The result is a manufacturing environment designed to support dependable optical performance and consistent delivery standards.

It shows that KUPO Optics is set up for controlled, precision-driven optical filter production. The page highlights the cleanroom environment, IAD coating equipment, substrate cleaning, custom cutting, spectral inspection, and surface-quality control as part of one connected manufacturing workflow.
The cleanroom helps KUPO Optics reduce airborne contamination that could affect coating performance or surface quality. For customers, that supports cleaner coatings, better consistency, and a lower risk of contamination-related defects.
KUPO Optics uses large coating chambers equipped with Ion Assistant Deposition technology and planetary rotating trays. This combination helps produce coatings with strong adhesion, good density, and more uniform optical behavior across the substrate.
Ultrasonic cleaning prepares substrates before coating starts. That step helps improve coating adhesion and surface cleanliness, which is important when customers need dependable optical performance.
KUPO Optics can handle both linear and laser cutting, giving the company flexibility for custom shapes, standard formats, and application-specific sizing. Filters can also be cut from large 450 mm diameter plates for more specialized project requirements.
KUPO Optics uses spectrometers to scan coated filters and verify that they match the required optical targets. Filters are checked before stocking and again before shipment to reinforce accuracy.
KUPO Optics uses dedicated inspection instruments to identify any filter that does not meet its scratch-and-dig criteria. That means surface inspection is part of the company's effort to ship filters that meet high visual and manufacturing standards.
The main takeaway is that KUPO Optics has built its facility around controlled processes, precision equipment, and repeatable quality checks rather than production capacity alone.
