Application Fit & Sizing Matrix

Operational Limits
pressure: Atmospheric to 2 bar (29 psi) max, typical for LED/sensor housings
other spec: UV exposure: 5000+ hours at 0.35 W/m² @ 340nm with <5% transmittance loss; Flow rate: N/A (static housing); Slurry concentration: N/A (non-flow application)
temperature: -40°C to +125°C continuous, up to +140°C intermittent
Media Compatibility
✓ Indoor/outdoor LED lighting assemblies ✓ Industrial sensor protection (photoelectric, proximity) ✓ Automotive lighting/indicator housings
Unsuitable: Continuous exposure to strong solvents (ketones, esters, chlorinated hydrocarbons) or high-pressure water jets (>100 psi)
Sizing Data Required
  • Lens diameter/optical aperture required (mm)
  • Mounting interface specifications (thread type, flange, snap-fit)
  • Required IP rating (ingress protection) for environmental sealing

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Stress Cracking
Cause: Exposure to incompatible chemicals (e.g., certain solvents, cleaning agents) or residual molding stresses combined with environmental stress, leading to micro-crack initiation and propagation.
UV Degradation and Yellowing
Cause: Prolonged exposure to ultraviolet light, causing polymer chain scission, loss of optical clarity, and embrittlement, especially in outdoor or high-UV environments.
Maintenance Indicators
  • Visible surface crazing or fine cracks under inspection light
  • Noticeable discoloration (yellowing) or cloudiness affecting light transmission
Engineering Tips
  • Implement regular cleaning with only approved, non-aggressive solvents (e.g., isopropyl alcohol) and avoid abrasive materials to prevent surface damage and chemical attack.
  • Apply a UV-protective coating or specify UV-stabilized polycarbonate grade during design, and ensure proper mounting to minimize thermal cycling stresses.

Compliance & Manufacturing Standards

Reference Standards
ISO 13468-1:2019 (Plastics - Determination of total luminous transmittance and reflectance) ASTM D1003-21 (Standard Test Method for Haze and Luminous Transmittance of Transparent Plastics) CE Marking (EU Directive 2014/35/EU for electrical equipment safety)
Manufacturing Precision
  • Wall Thickness: +/-0.1mm
  • Optical Surface Flatness: 0.05mm
Quality Inspection
  • Dimensional Verification with Coordinate Measuring Machine (CMM)
  • Optical Clarity and Haze Measurement per ASTM D1003
