Frequently Asked Questions

Optical-grade polycarbonate — high clarity and impact resistance. Acrylic available for superior optical clarity but is more brittle.

Light tinting (10–20% grey) typically has no effect on standard scanner wavelengths. Confirm against your scanner's window transmission spec before ordering tinted.

1.0–2.0 mm; 1.5 mm is most common. Thinner windows cause less optical path shift for close-focus scanners.

Yes. CNC-cut to any 2D profile — oval, rounded-corner rectangle, or custom outline matching your housing aperture. ±0.1 mm tolerance.
