Yes. Felix Glass supports custom diameter, radius, thickness, geometry, tolerances, mounting interface, optical requirements and coatings according to approved drawings and project requirements.

Common options include sapphire, fused silica, quartz glass, BK7/K9, CVD‑ZnS and CVD‑ZnSe. Selection depends on wavelength, environment, mechanical and thermal requirements, optical performance and cost.

Not directly. Different substrates have different mechanical strength, so wall thickness, pressure rating and tolerance must be re‑evaluated when switching material.

Yes. Hemispherical, spherical and custom configurations can be evaluated against geometry, dimensions, thickness, interface and tolerances.

Yes. AR and BBAR coatings can be configured according to operating wavelength, incidence angle, transmission requirements and system design.

Yes. Custom solutions are available for underwater cameras, ROV systems, subsea inspection, marine monitoring and sensing. Material and geometry depend on pressure, depth, optics and mechanical design.

Suitable prototype projects may start from 1 piece. Production quantities can then scale according to the approved project requirements.

Suitable standard configurations may require approximately 3–5 working days. Final timing depends on material, geometry, polishing, coating, inspection and quantity.

Yes. Felix Glass supports transition from prototype validation to pilot, small-batch and larger-volume production.

Inspection reports, material documentation and batch quality records can be provided according to agreed project and documentation requirements.

Four key items for valid RFQ: drawing / dimension, operating water depth / pressure, lens wavelength & optical requirement, quantity. Share drawings, material preference, coating, mounting interface and environmental conditions whenever available.
