KUPO Optics manufactures optical filters and coatings for wide range of application including medical, fluorescence, machine vision, astronomy, defense systems, entertainment, and more.


Flexibility and Customization

We stock abundant and diverse filter inventory to fulfill rush order. Our experienced R&D team is also happy to provide customized filters that meet your most demanding requirements.


KUPO Dichroic Filter

KUPO optical filters are renowned for their precision and constituency due to the excellent work of our coating chambers with planetary revolution and the assistance of the Ion Assistant Deposition (IAD). Base on MIL-M-13508C regulations, the rigorously strict manufacturing process creates filters that strongly resist the damage from abrasion, humidity, and flaking. The performance never degrades.

Our procedures are completely in accordance with the ISO 9001 to ensure quality uniformity, making filter at narrow tolerance, within ±1.5% at T50%. KUPO Optics is dedicated in pursuing the visualization of any possibilities through continuous research and development. We are relentless in our commitment to provide quality products and better service to our customers.

We dedicates ourselves to ensure product quality and customer satisfaction. Please contact us if you have any inquiries, your requests are always welcome and will be addressed as soon as possible.


Anti-Reflection Coatings

Anti-reflection (AR) coating is a solution to reduce glass glare and reflection, and enhancing the transmission of visible light.
We supply single side and double side AR coating. With single side coating, except for being an economical option, it can be an enhancer of certain filter as well. For example adding AR coating on UV cut filter to improve the transmission of visible light, or on a beam splitter to avoid Fresnel reflection.
With double side AR coating, it maximizes the performance of AR coating with average transmission rate over 98%.
