Optical & Application Guides for Machine Vision Lighting
Technical guides on infrared, UV, LED color selection, IP69K stainless lighting, and sector applications from automotive to medical machine vision.
These guides don't start from a product — they start from the physical problem a camera is failing to solve: a reflection that saturates the sensor, a color that disappears into its background, a defect that's invisible under normal light. Each one explains the underlying optical principle first, then points to the lighting geometry and wiring that actually implement it.
Industrial Infrared Lighting
Why infrared lighting sees through materials that look opaque under visible light, and how to apply it in machine vision — read our full guide.
Ultraviolet (UV) Lighting
Why some defects are invisible under any normal light, and how UV-excited fluorescence reveals them in machine vision inspection — full guide.
Choosing LED Color
Why a monochrome camera can miss a color-coded defect entirely, and how choosing the right LED wavelength restores contrast — read our full guide.
IP69K Stainless Lighting for Pharma & Food
Why standard aluminum lighting fails in corrosive pharmaceutical and food washdown environments, and what IP69K, CIP/SIP resistance and 316L actually certify.
Automotive Machine Vision
Why metallic and painted automotive parts defeat generic lighting, and how to match lighting geometry to weld and surface defects — full guide.
Medical & Pharmaceutical Vision
Why translucent tablets and reflective blister foil defeat generic lighting, and how backlight silhouettes and diffuse domes solve it — full guide.
Brightfield vs Darkfield
Why the same scratch can appear bright or dark depending on lighting angle, and how to choose between brightfield and darkfield illumination.
Eliminating Reflections with Polarization
Why a saturated glare hot spot destroys image data no exposure setting can recover, and how crossed polarizing filters remove it — full guide.
Lighting for Area Scan Cameras
Choosing lighting for an area scan camera: match field of view, exposure and geometry to the sensor. Continuous vs strobe, area-scan vs line-scan compared.
B2B Integration Considerations
EMC Compliance
Choosing an optical technique (wavelength, polarization) has no EMC impact by itself — immunity to disturbances is decided at the wiring and shielding level, covered in our Wiring & Integration silo.
LED Thermal Management
Some techniques — overdrive, UV, high-power IR — place a heavier load on the electronics and thermal dissipation of the light, a point to anticipate as early as the optical study phase.
Supply Continuity & Dual Sourcing
Documenting the underlying physical principle — not a single product reference — makes it easier to reproduce the solution with an alternative source if a supply chain disruption occurs.
