UV Block

Those products are specifically studied and manufactured to manage the UV spectrum.

In particular the UV Block filter reduces the ultra-violet component of the emission light to a negligible value:
UV transmission <0.2% below 380 nm.

The transmission in the visible spectrum is almost total (T>90%).

To enhance the transmission coefficient, those filters can be coupled with an antireflection coating by simply depositing the antireflective coating on the other side of the glass substrate.
