Fresnel Lens Specifications
   Fresnel Lens Specifications      Fresnel lenses can either be positive if converging or negative if diverging.
   Your choices are...         
   Positive Lens       A fresnel lens with a positive focal length. 
   Negative Lens       A fresnel lens with a negative focal length. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Lens Application:      Lens application refers to the desired wavelength range for the lens. This wavelength range is mostly dependent upon the lens material.
   Your choices are...         
   Infrared       Lenses are designed for use in the 750 nm to 2500 nm wavelength range. 
   Visible       Lenses are designed for use in the 380 nm to 750 nm wavelength range. 
   Ultraviolet       Lenses are designed for use in the 4 nm to 380 nm wavelength range.

Performance
   Focal Length       The effective focal length is the distance from the lens the light converges. Focal lengths are positive for a converging system and negative for a diverging system. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Grooves:       Fresnel lens use concentric grooves to focus light. The number of grooves is measured by grooves per millimeter. 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
   Thickness:       The thickness of the lens at its center. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
