Item	Description
Photopia 3.0 Foundation	This is the base program including the entire library of over 400 lamps and a material library that is limited to perfectly specular reflector materials and clear transmissive materials. The main restriction is that the material library does not include materials that scatter light upon reflection or transmission.
General Materials Library	The library consists of BRDF/BTDF data for over 350 commonly used reflector and refractor materials commercially available from major material vendors such as Alanod, ACA, Anofol, Sacall, Foremost, Reflek, Abrisa, Cryo, Spectrus (ALP) and others. If you use materials such as semi-specular aluminum, white paint, textured aluminum, prismatic lenses, white diffusing lenses or perforated steel, then this module is required. LTI Optics also provides material measurement services for special materials you use in your products.
General Refractor Module	The refractor module adds the ability to model 3D refractors. Refractor elements are modeled in the same way as reflector elements, so there is almost nothing additional to learn. General refractors are modeled by drawing the actual prism or lens geometry in your CAD program. Photopia uses the index of refraction and the extinction coefficient of the material to accurately model refraction into the material, Fresnel reflections from the inner and outer surfaces of the material, total internal reflection (TIR) effects and losses due to absorption within the material. The Refractor Module can be used for LED modeling and lens design, roadway refractors, Fresnel lenses, light pipes, signaling lenses or any other design for which you need to control light using refraction. These analyses go beyond the scope of the Foundation with the BRDF/BTDF material library, which will only analyze refractors that are available for measurement by LTI Optics. Note that homogeneous prismatic lenses, white translucent lenses and perforated surfaces are available in the General Materials Library and do not require the Refractor Module.
