UV Transmission Filters

With rapid development of newtechnology, the usage of light has expanded to invisible region. Due to the characteristic of high energy, the applications of UV filter are growing very fast.

From time to time the UV LED emits wide range of UV, but this may not be suitable for specific application as the UV range is too wide. Therefore, adding a UV filter is able to narrow the range of the UV LED by filtering out the unwanted UV range. 
 
KUPO Optics provides different types of UV transmission filters with high transmitting rate on designated and commonly used UV. While transmitting the UV, our filter also reflects visible light that can be utilized in coaxial light source.
