Screening campaigns and prototype coating projects.
Bring a broad coating/material space, a narrower sample question, or a candidate region from an earlier screen. xemX makes physical samples, measures what matters, and helps choose the next validation step.
Concept visual: a physical coating library, measured maps, and selected follow-up samples.

Physical workflow
One physical workflow, three project shapes.
When one-at-a-time coating tests are too slow, xemX creates related physical variants, measures them, and identifies regions worth the next test. Narrower questions can start from selected coatings, uniform films, coated coupons, or scoped test structures.
Make variants
Create controlled coating or thin-film libraries instead of testing one recipe at a time.
Shortlist candidate regions for supplier discussion, prototype validation, repeat deposition, or technical follow-up.
xemX narrows the coating, material, or film regions worth testing next. Final product, device, field, and qualification testing usually remain downstream.
Project types
Choose the project shape by the decision you need to make.
Some projects start with a physical screening library. Others start with a specific coating, film, stack, or sample question before a supplier round, prototype build, or validation test.
Screening campaign
Explore many related coating or thin-film variants and map which regions deserve follow-up.
Prototype coating project
Make selected coatings, uniform films, coated coupons, or scoped test structures when the target question is already narrower.
Follow-up deposition
Repeat candidate regions from a screen as controlled films, coated samples, or scoped test structures for the next validation format.
Physical samples
From physical variants to follow-up samples.
Concept visual: coated sample variants.
Coated metal and glass samples show how related variants can be compared.
Concept visual: selected follow-up samples.
Selected regions from a map can move into coated samples, follow-up films, or scoped test structures.
Prototype samples
Prototype coating projects can start directly.
If a team already has a target coating, material region, stack idea, or supplier question, xemX can use sputter deposition to make small-format physical samples. The format depends on substrate, geometry, layer stack, measurement route, and the later validation step.
Coated samples
Deposit selected coatings on customer-relevant substrates or coupons when the geometry and process route fit.
Uniform films
Produce selected compositions as controlled films for optical, electrical, mechanical, corrosion, or surface testing.
Scoped test structures
Scope simple stack-relevant samples when the substrate, mask, layer stack, and validation route are technically realistic.
xemX can support prototype coating and selected test-structure work. Full device integration, product qualification, and production transfer usually remain with the customer or downstream partner.
Where it fits
Start with the surface or validation problem.
Use xemX when a coating, surface, or thin-film decision has too many options for blind supplier, prototype, device, or field validation.
Glass / optics
Glass and optical surfaces
Reflectance, color neutrality, transparency, haze, cleanability, fingerprints, scratch, and durability.
Supplier samples or one-off recipes do not cover the coating, finish, surface, or material region you need to compare.
Validation is expensive
Full prototypes, device tests, coupon tests, or field validation are too slow to run blindly.
Tradeoffs matter
Appearance, durability, conductivity, corrosion response, phase, texture, or optical behavior must be balanced.
Output needs to travel
Measured maps, candidate regions, and follow-up sample recommendations support internal, supplier, or partner discussions.
Next step
Discuss project fit.
Bring a coating, surface, thin-film, material, process, or prototype sample question. xemX helps determine whether physical screening or a small-format sputter deposition project can support the next validation step.
