Overview
A 3D body scanner mirror is a precision optical component that directs structured light patterns onto a subject and collects the reflected data for triangulation. In an ODM arrangement, the mirror is designed to integrate directly into a scanner housing while meeting the specific mechanical and optical constraints of the end‑use system.
The mirror operates as a front‑surface element, eliminating ghost images caused by refraction through a substrate. This configuration is essential for achieving sub‑millimeter measurement accuracy across the full field of view required for human body scanning.
Core Technology
The substrate is typically a low‑expansion glass such as BK7 or fused silica, selected for its homogeneous refractive index and minimal thermal drift. A thin metallic overcoat—commonly enhanced aluminum with a protective overlayer—provides reflectance exceeding 90 % across the visible to near‑infrared spectrum (400 nm–1000 nm).
Surface figure is controlled to λ/10 peak‑to‑valley at 632.8 nm, ensuring that wavefront distortion does not degrade the structured light pattern. The coating stress is balanced to prevent substrate bowing over the expected operating temperature range (−10 °C to 50 °C).
Mechanical Design
External dimensions are customized to fit the scanner’s optical path, with typical diameters ranging from 30 mm to 80 mm and thicknesses from 5 mm to 12 mm. Mounting features include precision‑ground datum edges or threaded inserts that allow repeatable positioning within 5 µm.
To resist vibration from scanning mechanisms, the mirror is often bonded to a kinematic mount using a low‑outgassing adhesive. The adhesive layer thickness is controlled to < 20 µm to avoid introducing optical wedge.
Optical Performance
Resolution is defined by the smallest detectable displacement in the reconstructed point cloud, typically 0.2 mm for a system operating at 500 mm working distance. Measurement accuracy, expressed as RMS error between scanned and reference surfaces, falls below 0.5 mm over a 1.5 m × 0.5 m scanning volume.
The mirror’s clear aperture is sized to accommodate the full beam diameter of the projector and camera lenses, usually 80 % of the substrate diameter to avoid vignetting. Angular deviation introduced by the mirror is held under 2 arc‑minutes, ensuring that the structured light pattern remains geometrically faithful.
Typical Applications
In apparel manufacturing, the scanner captures body dimensions for made‑to‑measure patterns, reducing material waste and lead time. The mirror’s low scatter ensures that the structured light pattern remains sharp on curved surfaces such as shoulders and hips.
Virtual fitting rooms rely on rapid, high‑density point clouds to drive real‑time avatar deformation. The mirror’s broad spectral response supports both visible light and near‑infrared projectors, allowing the same hardware to operate under varying ambient lighting.
Ergonomic assessments and prosthetic design benefit from the scanner’s ability to record subtle surface variations. The mirror’s minimal thermal drift guarantees repeatable measurements across multiple sessions conducted in different environmental conditions.

Customization & ODM Support
Substrate options include BK7 (cost‑effective, good homogeneity), fused silica (UV transparency, lower thermal expansion), and Zerodur®‑class ceramics for ultra‑low drift applications. Each material is supplied with a certificate of conformance detailing bubble content, inclusions, and striae grade.
Coating choices range from standard enhanced aluminum (90 % average reflectance) to dielectric stacks tailored for specific laser wavelengths (e.g., 1064 nm) with reflectance > 98 % and laser damage threshold > 5 J/cm². Optional hydrophobic or oleophobic top layers can be added to ease cleaning in high‑touch environments.
Geometric customization covers diameter, thickness, radius of curvature (for focusing or collimating variants), and edge finish (beveled, chamfered, or ground). Mounting interfaces are engineered to match existing scanner hardware, minimizing redesign effort for the OEM.
Engineering support includes ray‑trace analysis to validate field of view and illumination uniformity, finite‑element assessment of thermal-mechanical stability, and prototype production runs of 5–20 pieces for functional evaluation before volume tooling.
Quality Assurance
Surface figure is measured with a Fizeau interferometer at multiple azimuths; results are logged and compared against the λ/10 specification. Coating adhesion is validated via a tape test per ASTM D3359, with a minimum rating of 4B required.
Environmental durability testing includes temperature cycling (−20 °C to 60 °C, 10 cycles), humidity exposure (85 % RH, 168 h), and UV stability (300 h at 0.8 W/m²). Post‑test inspection confirms that reflectance change remains < 1 % and surface figure shift < λ/20.
Each lot receives a unique serial number, and a test report is supplied with shipment documenting interferometric maps, coating uniformity scans, and visual inspection criteria. Traceability extends to raw material lots and coating run identifiers.

Frequently Asked Questions
Can the mirror dimensions be adapted to an existing scanner housing?
Yes. We require the housing’s clear aperture, mounting hole pattern, and any axial constraints. Our optical engineers then produce a detailed ICD (interface control drawing) for approval before prototyping.
What information is needed to obtain a quotation?
Key inputs include: desired substrate material, coating specification, outer dimensions, thickness, mounting features, required surface figure, and anticipated annual volume. Providing a schematic or 3D model of the scanner’s optical path accelerates the quote.
How is quality verified for each shipment?
Every lot undergoes interferometric surface figure testing, coating reflectance sampling, and adhesion testing. A Certificate of Conformance summarizing these results is included with the delivery.
