About us

KUPO Optics was founded in 1992, aiming at offering the finest quality of optical coatings and filters. Thanks to uncompromising to the product criteria, we have been established an excellent reputation in professional optical filter industry.

State-of-the-art Facilities

We keep investing in the state-of-the-art production equipment including planetary coating, accurate linear and laser cutting machine, high resolution spectrometers and the likes. Those advanced facilities makes filters and coatings perfectly and precisely.

 

Wide Range Applications

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.
 

 

IR Cut Off Filters

KUPO Optics provides IR Cut-off filters that effectively block infrared and transmit much of the visible light. It cuts off infrared so that the imaging will not be affected by infrared while presenting natural and accurate coloration in modern camera system.
 
Though we cannot see it, infrared exists in common light sources and can be detected by CCD or CMOS sensor. As those machine eyes can see infrared up to around 1000nm which will cause inaccurate coloration. Therefore, in order to assure image quality, infrared must be blocked. That is why IR cut-off filter is needed.
