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.
 

 

Hot Mirrors

Hot mirrors is able to reflect near infrared (NIR) while transmits great amount of visible light. With this feature, hot mirror is a great solution to protect components against the damage by the heat.
 
Near infrared is the source of the heat. Some components that are sensitive to infrared will be damaged after being exposed to infrared for a long time. In order to protect those components, placing a filter that blocks IR is the solution.
 
On the other hand, with heat reflection feature, placing a hot mirror in front of a light source is able to reduce the heat distribute to the environment. Take spot light for example, placing a hot mirror in front of the light source, the person who is standing in front of spot light will feel comfortable as less heat is transmitted.
