Machine Vision Optical Accessories
Accessories often determine whether a good lighting concept survives production. Diffusers, polarizers, filters, mounts, and cables help control glare, wavelength, geometry, repeatability, and installation reliability.
Accessory types
- Polarizers for reflection control
- Diffusers for uniformity and glare reduction
- Bandpass, IR, UV, and protective filters for wavelength isolation
- Adapters, extension tubes, brackets, and mounting hardware for repeatable geometry
Selection inputs
- Target wavelength
- Lens/filter thread, adapter, or extension tube requirement
- Light geometry and working distance
- Environmental and cleaning requirements
- Cable routing and connector constraints
Common problems
- Polarizer angle not locked after setup
- Filter blocks the useful wavelength
- Mount drift changes inspection contrast
- Diffuser improves uniformity but removes needed shadows
