Request InfoWestech Optical CorporationWestech 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.
