The Ventana™ Power Train

Light Prescriptions Innovators announces the Ventana™ Optical Train, a complete off-the-shelf optics solution for the CPV module manufacturer and integrator. Ventana™ solves the initial design and tooling costs of the module manufacturer who wants to develope a new generation CPV product utilizing the best architecture available.

The integrator nature of the FK architecture, along with its advanced 4-fold geometry, overcomes most chromatic effects, yielding high performance levels within the entire acceptance angle cone.  The SOE design protects the cell assembly from meniscus losses, facilitates electrical and moisture insulation, permits mechanical hold downs and optical coupling using non-structural gels that are less sensitive than adhesives to degradation from high UV concentration.

The Ventana Power Train

Optical Train Efficiency (POE+SOE) >83%
