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
When and how to use infrared (IR) lighting in machine vision: penetrating packaging, reducing glare, and working discreetly alongside visible light.
Ultraviolet (UV) Lighting
Using UV lighting to reveal fluorescent markings, detect contamination, cracks and adhesive traces invisible under standard visible light.
Choosing LED Color
A practical guide to choosing red, blue, green, white or IR LED wavelengths based on target color, surface texture and contrast requirements.
IP69K Stainless Lighting for Food
IP69K-rated stainless steel lighting built to survive high-pressure washdown, hygienic design standards, and harsh food and beverage environments.
Automotive Machine Vision
Lighting strategies for automotive inspection: weld seam control, surface defect detection, assembly verification and robust in-line durability.
Medical & Pharmaceutical Vision
Lighting for pill counting, blister pack inspection, label verification and cleanroom-compatible machine vision in medical and pharma lines.
Brightfield vs Darkfield
A side-by-side comparison of brightfield and darkfield illumination techniques and when each one reveals surface defects best.
Eliminating Reflections with Polarization
How polarizing filters on lights and lenses remove specular reflections and glare from metallic, glass or wet surfaces during inspection.
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.
