Moldable UV transmitting glass IHU250HOptical filters

The IHU250H is a long-pass filter that transmits 50% of UV and visible light at 250 nm. As the processing temperature range is almost the same as that of ordinary glass, IHU250H can also be used as a molding material. We can also mold them into aspheres and lens arrays.


*IHU150E is now under development.

One of the characteristics of IHU250H is that its expansion rate is closer to that of a metal than that of quartz. The IHU250H can also be molded and used as a cover glass for LED chips by metallizing the lens flange. Please contact us if you have any drawings of the lens or other desired specifications.
