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.
 

 

DICHROIC FILTERS

We offers dichroic filters coated with hard dielectric thin-films. The dielectric thin-films filter out the unwanted regions of visible spectrum and let the light of certain wavelength transmit so that you will see different colors when light passing through the dichroic filter.
 
Planetary-runningcoating machine lets thin-films evenly attach to the glass substrate which guarantees consistency of optical specification from different pieces and different batches.
 
With Ion Assistant Deposition (IAD), the thin-films will firmly attach to the glass substrates with great density which makes the filters greatly resistant to the environmental degradation.
 
There are over 70 colors available which offers flexibility for you to choose the most suitable one for you.
For your unique project we are able to develop the required color as well.
