Design of Novel Compound Fresnel Lens for High-Performance Photovoltaic Concentrator [PDF]
International Journal of Photoenergy, 2012 We present a new design of compound Fresnel-R concentrator which is composed of two lenses: a primary lens (Fresnel lens) that works by total internal reflection at outer sawteeth but refraction at inner sawteeth, and a ringed secondary lens that works ...

Influence of Micro-Scale Surface Texturing on Light Distribution From Luminescent Downshifting Layers for Next-Generation Greenhouses. [PDF]
Glob ChallThis work investigates two different luminophores that convert ultraviolet to red light along with a wide range of microstructures to maximise outcoupling of the luminescence as well as the incoming solar radiation onto the greenhouse floor. Starting with small‐area (25 cm2) luminescent down‐shifting (LDS) layers, the best designs are then evaluated ...

Peli prism fitting for homonymous hemianopia: Case series for fitting variations
Indian Journal of Ophthalmology. Case Reports, 2023 Peli prisms are Fresnel prisms for visual field expansion in homonymous hemianopia. They can be dispensed as temporary (press-on) or permanent prisms. In this case series, we discuss the general fitting techniques and report fitting Peli prisms in four ...

PIN-PMN-PT Surface Planar Waveguides Realized via He<sup>+</sup> Implantation. [PDF]
NanophotonicsHelium‐ion implantation turns bulk PIN‐PMN‐PT relaxor ferroelectric crystals into high‐quality planar optical waveguides. The guiding surface layer retains its single crystallinity and large electro‐optic response without postimplantation annealing, whereas a buried damage layer acts as the optical barrier.

Prismatic treatment of acute acquired concomitant esotropia of 25 prism diopters or less
BMC Ophthalmology, 2022 Background This study aimed to assess the efficacy of prismatic treatment in a step-by-step manner to reduce prismatic strength in acute acquired concomitant esotropia (AACE) of 25 prism diopters (PD) or less.

Photonics, 2022 For optical beams transmitted by a right-angle prism, the Goos–Hänchen shift can never be seen as a pure effect. Indeed, the lateral displacement, caused by the total internal reflection, will always be accompanied by angular deviations generated by the ...

Prism vergence measurements following adaptation to a base out prism [PDF]
, 2000 This study examines the effect of adaptation on the prism vergence range following an induced deviation. Five young adult subjects, with normal binocular functions, underwent fusional verfence testing to base in prisms before and after wearing a 10(Δ ...

Journal of Ophthalmology, 2020 The paper points to the principle of prisms: if a prism is placed in front of the strabismic eye, images of objects impinging upon the peripheral retina are projected to the central pit, which creates optimal conditions for cooperation of both eyes and ...
