Features

UV Fused Silica Substrates

Optically finished substrates are made to stringent standards, ready for your specialty coating. These high quality substrates have high flatness, low scratch-dig and low parallelism. Order Newport substrates to supply to custom optical coating houses to save on overall costs.

Includes Optical Grade Jewel Box

These substrates are specially packaged with the customer in mind.  Each substrate comes in an optical grade jewel box with plastic insert.  Instead of adhering the label on the top surface, the label is placed in the inside top cover of the jewel box.  This way once the coating is applied to the substrate, the same packaging can be used again for the finished optic with a new label.
