Wedged Optical Window, Substrate, 50.8 mm, Fused Silica
Model: 20Q20-NL
Product Series Overview
Fused Silica Window SubstratesThe 20Q20-NL Wedged Window Substrate is 2.0 inch (50.8 mm) diameter uncoated fused silica substrate.
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. 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 on 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 with a new label.
