Frequently Asked Questions

What materials do you use for encoder disks?

We manufacture encoder disks on glass or ceramic substrates, depending on environmental requirements. Glass offers high optical clarity, while ceramic provides superior thermal and mechanical stability.

Can you produce custom photomask designs?

Yes, we accept CAD files (GDSII, DXF, etc.) and can produce custom photomasks with line widths down to 1µm. Our chrome mask blanks offer high resolution and low defect density.

What is the lead time for custom optical components?

Standard lead time is 15–25 days depending on complexity. Prototypes can be delivered in as little as 7–10 days. We guarantee on-time delivery.

Do you offer coating services?

Yes, we provide anti-reflective (AR), high-reflective (HR), and conductive coatings. Custom coating specifications are available upon request.

Are your ceramic pressure sensor cores temperature compensated?

Yes, our piezoresistive ceramic sensor cores include temperature compensation for stable performance across a wide operating range (-40°C to +125°C).
