Westech OEM board lenses offer higher MTF and better mechanical integrity. Standard coverage is for 1/3-in., 1/2-in. or 1/1.8-in. formats. Lens designs are four, six or eight elements. Westech can easily generate a design proposal for custom requirements or modify an existing lens to quickly meet a unique condition. Lenses can be ruggedized to meet NEMA requirements or generally harsh conditions. Custom IR filters may also be incorporated into the assemblies. Don’t pay catalog prices for OEM optics.
