Engineering & Procurement Risks

6 Common Challenges in Infrared Dome Projects

Wrong IR Material

Different infrared materials serve different wavelength ranges and system requirements.

Solution: Match material → wavelength → optical system before production.

Complex Dome Geometry

Diameter, radius, thickness, height, clear aperture and mounting features must work together.

Solution: Custom dome geometry manufactured from your drawing or engineering specification.

Optical Surface Quality

A mechanically accurate dome is not necessarily an optically suitable dome.

Solution: Precision grinding and optical polishing according to the required optical specification.

Incorrect IR Coating

An AR coating must match the substrate and actual operating wavelength.

Solution: Application-specific MWIR AR / LWIR AR / broadband IR AR coating options.

Environmental Exposure

Outdoor and industrial IR systems may face temperature variation, moisture, dust, vibration or other environmental conditions.

Solution: Evaluate material, coating, edge configuration and mounting requirements as one system.

Prototype-to-Production Risk

A successful prototype must maintain dimensional, optical and coating consistency during production.

Solution: Controlled transition from prototype → validation → pilot → production.

From Drawing to Production

Manufacturing & Delivery Process

STEP 01

Engineering Review

Send drawing, dimensions, wavelength, application or reference sample.

STEP 02

Material & Specification Confirmation

Confirm substrate, geometry, optical requirements and coating.

STEP 03

Prototype

Manufacture first sample for engineering validation. Typical reference: 3–5 working days.

STEP 04

Validation & Pilot

Confirm dimensions, optical surface and coating before production. Typical small-batch reference: 7–10 working days.

STEP 05

Production

Repeat manufacturing according to approved specification. Typical production reference: 10–15 working days.

Final lead time depends on material, geometry, coating, inspection requirements and quantity.
