UV Hot Mirrors

NTFL produces and stocks quartz UV hot mirrors in the following sizes:

• 5” x 5” x 0.090”
• 6” x 6” x 0.120”
• 7” x 7” x 0.120”

However, we can produce parts to almost any requested size.

NTFL UV hot mirrors act on both direct and reflected radiation to reduce the amount of visible and infrared energy without degrading the transmitted UV energy.  The mirrors are situated on the output side of the radiation source and are almost universally made of fused silica or quartz coated on both sides.

Since UV hot mirrors are less efficient than UV cold mirrors, many UV curing systems utilize both types of optics.
