Looking for generation I (E141/2) or II (E361/2/3) aperture masks for S101 or S171 substrates?

We have discontinued our generation I and generation II substrates and masks. The replacement 8-pixel design allows you to create either eight small individual pixels or a single large pixel. Contact us for more information, technical support and advice, or for help migrating to the new system.
