Real world uses of Photopia
Expert optical design consulting, from the creators of Photopia.
In addition to Photopia, LTI Optics provides a complete range of optical design services. Our staff has extensive experience in optical design and analysis, optical software development, source modeling, and material characterization. We have also personally trained lighting manufacturers throughout the world, teaching them lighting fundamentals, optical modeling and optical design techniques. Through our wide range of clients, we have been able to gain experience in many industries and over large ranges of product, resulting in over 20 granted US Patents. A few specific examples are shown in our Project Portfolio.

Design Type: TIR Lens
Narrow beam RGBW color changing theatrical light. Each TIR lens has an LED with RGBW in a single TIR lens to minimize rainbow edges in shadows. Optics mix all colors smoothly over the beam, while maintaining tight beam control.
Client: Tactical Lighting Systems
Tactical Lighting Website
Design Type: Lens
Tactical Lighting Systems, a company specializing in mobile airfield lighting for the american military, contracted us to design a range of optics for the various lighting devices required around an emergency or temporary airfield. The multi-function devices needed to meet strict intensity distribution requirements at the minimum size and power budget since they were powered via PV charged batteries and needed to fit within as small a package as possible.

Reflector and lens optics have been designed for LED headlamps and lanterns for the leading outdoor equipment manufacturer Black Diamond. All headlamps use compact Fresnel/TIR collimator style lenses allowing low profile packaging designs. Lanterns use a glare free double reflector system that hides the direct view of the source, while the Voyager smoothly blends the beam from a second optic on the bottom surface to create a full light distribution when hung in a tent or from a tree branch.
Client: Solartron Energy Systems
Design Type: Reflector
Canadian clean-tech company Solartron Energy Systems engaged us to design a 7m diameter dish reflector for concentrated photovoltaics (CPV) with a 1000X concentration ratio. The requirement was to distribute the concentrated light as uniformly as possible across the square shaped PV area to maximize the energy conversion of the device.
Design Type: Reflector + Lens
The Fascia Wash is a wall mounted luminaire designed to light large wall surfaces as evenly as possible with as wide a spacing as possible. The luminaire offers an alternative to floodlighting which requires luminaires mounted away from the building. A barrel style Fresnel lens was used in conjunction with internal reflector optics to produce the desired performance. The luminaire stands only 14" off of the wall surface yet achieves a mounting height of 20' and a spacing of 40'.
LTI designed a patented reflector/refractor optical system using a white diffuse reflector that enabled a completely new product to be designed with a priority put on the product's appearance. This product is the first to transform the utilitarian devices which have historically populated this industry into a component which compliments architecture. The unique optical system not only allowed for a lower profile product, it also produced a better light pattern allowing it to be safely seen from more viewing angles than other devices on the market.
Client: Outdoor Manf
Two new glass refractors were designed for an outdoor lighting manufacturer to add to their existing range of optical systems. The new refractors needed to provide improved spacing performance over competitive products based on illuminance and roadway luminance criteria. To design the new refractors, LTI developed specialized refractor design tools so that various prism configurations could be quickly created and analyzed in Photopia. The optimization of such a complex part would not have been possible without the ability to automatically generate the prism profiles for the inner and outer surfaces.
Two new reflectors were designed for an outdoor lighting manufacturer to add to their existing range of optical systems. The new reflectors needed to provide an IES Cutoff distribution while matching or improving upon the spacing performance of their existing products based on illuminance, roadway luminance and veiling luminance criteria. The new reflectors provided this as well as improvements in the appearance of the light pattern and the overall amount of light on the roadway. The designs were optimized to provide the best performance with the smallest number of assembled parts ensuring that the manufacturing costs were minimized.
New refractor designs were created to maximize visibility for LED-based mobile signage. Special design characteristics were added to protect lens elements from the environment and implement a smooth exterior lens face to minimize the collection of debris. This new design exceeded all previous performance marks.
