Lenses
Matrox GatorEye is compatible with a C-mount lens. For more information
regarding selecting your lens, refer to Appendix C: Selecting a lens.
Keep the lens free of fingerprints and dust. Do not clean it with an alcohol-based
cleaning solution and do not spray water or cleaning fluids directly onto the lens.
Instead, use a pressurized air dispenser or a lens cleaning cloth to remove dust.
