KUPO Dichroic Filters

KUPO Optics offers dichroic filters that filter out unwanted regions of visible spectrum and let the light of certain wavelength transmit so that you will see different colors when the light passing through the dichroic filter. Our dichroic filter features great color consistency as they are placed on the same horizontal level when being coated. It also features great resistance to environmental degradation as it is coated with Ion Assistant Deposition which makes the thin films firmly attach to glass substrates with great density. 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. Except the Dichroic filters, KUPO provides various filters that can be applied to entertainment, medical, fluorescence, machine vision, astronomy, defense systems, and other professional applications. There are abundant amount of product stock available for immediate delivery. Our experienced R&D team is capable of supplying customized filters that meet your most demanding requirements. Choose us, and we will be your helpful partner on the path of success.

KUPO UV Cut off Filters

- KUPO provides UV blocking filter that is good at blocking unneeded UV in order to protect the objects exposed to UV and highly transmitting visible light.
- UV is included in a various light source like sunlight, halogen lamp, fluorescent lamp, and so on. Because of the characteristic of high energy, it will damage the object that is exposed to UV continuously. For example the art works illuminated by the light source or the coating of the camera lens exposed to sunlight.
- Except the UV filter, KUPO also provides many different filters that can be applied to entertainment, medical, fluorescence, machine vision, astronomy, defense systems, and more. 
- There are abundant amount of stock products that can be offered immediately. Moreover, our experienced developing team can also provide customized filters that meet your most demanding requirements. 
- Choose us, and we will be your helpful partner on the path of success.

KUPO Hot Mirrors and IR Cut off Filters

- KUPO IR Cut-off filters and hot mirrors features effectively blocking infrared and transmitting much of the visible light.
- Near infrared will damage component which is sensitive to it. After long exposure to infrared, the components will be damaged. In order to protect those components, placing a hot mirror is a perfect solution. 
- On the other hand, infrared can be detected by CCD or CMOS sensor which causes inaccurate camera imaging. Therefore, we must block infrared in order to assure image quality. That is why IR cut-off filter is needed.
- Except the IR filter, KUPO provides various filters that can be applied to entertainment, medical, fluorescence, machine vision, astronomy, defense systems, and other professional applications. 
- There are abundant amount of product stock available for immediate delivery. Our experienced R&D team is capable of supplying customized filters that meet your most demanding requirements. 
- Choose us, and we will be your helpful partner on the path of success.

KUPO Bandpass Filters

KUPO provides bandpass filters that are good at blocking the unneeded radiation and transmitting the designated wavelength, ensuring machine sensor to read the correct signal. In addition to the popular wavelengths such as 365/650/780/850/940nm, customize bandpass filter is possible.
