Stray Light & Baffling

Non-sequential stray-light analysis, baffle design, blackening specification and ghost-image suppression.

Service Overview

For low-light, star-tracker and IR systems, stray light is the enemy of contrast. AISYS runs non-sequential Monte-Carlo stray-light analyses in FRED / LightTools to identify critical paths, quantify PST and design baffle systems that meet MIL / R&D-grade requirements.

Deliverables include baffle drawings, vane geometry, blackening specifications and vendor-qualified black-anodise or Vantablack recipes.

What We Deliver

  • Non-sequential ray-trace stray-light analysis
  • Point Source Transmittance (PST) and Off-Axis Rejection
  • Baffle and vane geometry design
  • Ghost-image identification and suppression
  • Blackening specification (anodise, paint, Vantablack)
  • Field-of-view flare and lens-flare mitigation

Frequently Asked

What PST levels do you target?

Typical space / R&D targets are 1e-6 to 1e-10 depending on the sun-avoidance angle.

Which blackening options do you specify?

Black anodise, Aeroglaze, Acktar Magic Black, Vantablack — chosen per environmental spec.
