Retinal examination using direct ophthalmoscope is preferred over other techniques for screening purposes because of its portability and high magnification, despite its power sustainability and cost issues. With increasing number of low-cost sustainable devices available in the market, it is important to assess the efficacy of the devices. We compared three devices - Arclight ophthalmoscope, a D-Eye attached to iPhone 6, and conventional ophthalmoscope Heine K180 - in terms of ease of examination, usage, field of view, color rendition, patient comfort, length of examination, and closeness to the eye. Two trained optometrists examined 26 undilated eyes and graded the ease of retinal examination, ease of use and assessed vertical cup:disc ratio (VCDR). Patients reported their comfort level in terms of glare produced by the light source, length of examination and closeness to the eye. The examiners had a good agreement for all assessments. Of 26 eyes, VCDR assessment was not possible in 10/ 26 (38.4%) of the examinations, in (3/26, 11.5%) examinations with Arclight, in 0/26 examinations with D-Eye. Ease of use score was higher for Arclight and D-Eye than Heine. D-Eye had a relatively larger field of view than other 2 devices. Heine ranked first in color rendition. The luminance level of the high-beam setting of Arclight was more than twice that of Heine and D-Eye. Despite that, the patients reported experiencing uncomfortable glare in Heine (14/26, 53.8%), significant glare with Arclight (16/26, 61.5%) and some/no glare with D-Eye. The examination time was shorter when using D-Eye. Overall, D-Eye scored better in most of the evaluation items followed by Arclight.

The space investigation project "Lira-B" is purposed to perform a high-precision multicolor photometric all-sky survey of objects from 3 to 16 m. This investigation concludes in multiple photometric measurements in ten spectral bands from 200 to 1000 nm. Such telescope systems should provide maximum light gathering and meet stray light requirements. The main goal of the given work is optical design of the telescope system with lens hoods protecting against the parasitic illumination. Analysis of impact of the lens hoods' surface structure and coatings on the image quality is performed and ways to reduce the stray light in the system. The modeling is carried out using Zemax OpticStudio software in the non-sequential mode.

In this study, we propose a new micro-optical system with 1.65 zoom ratio for image stitching. The new system with four layers is based on microlenses and liquid lens arrays. In order to realize the zoom function, we design the first and the fourth layers by the liquid lens and we also set up the second and the third layers as the fixed lens to tilt the optical axes. The length of the system is 6.4 mm, the image size 8.6 x 6.6 mm(2), the field of view (FOV) 50 degrees in wide mode and the field of view 28 degrees in tele mode. The MTF and distortion are used to demonstrate the zoom function, the stitching function and the stitching with zoom function, respectively. We use the ZEMAX ray-tracing software to demonstrate the simulation of image stitching in wide and tele modes.

Two optical designs for marine beacon based on Direct In-line Package (DIP) LED is proposed and demonstrated. The luminous intensity of the marine beacon using DIP LED can achieve to the IALA recommendation's requirement of 5 nautical miles. The measurement of color coordinates can also fit the IALA recommendation's requirement. By the surface-structured TIR lens, we successfully keep the divergence angle to 68 degrees in the horizontal direction and converge to 8 degrees in the vertical direction.

Previously, we have studied the behavior of PDMS samples with variation of its synthesis parameters and it has been shown that there exists a direct relation with the variation of its physical parameters such as its refractive index. This property is useful to develop a surface with variable refractive index. In this work we present the design and study of a refractive surface PDMS-made multilayer lens with aspheric profile. The lens has been mounted into a mechanical mounting system to introduce low order aberrations.

We have designed a light-guide for lighting applications, including automotive headlamps. The light-guide is designed based on a free-form slab. Our intention has been to optimize the design for creating legal patterns. One of our objectives has been to investigate how the changes in the shape of the freeform light-guide affects the light pattern, and how the light source geometry affects the design. For prototyping purpose, we use a particular polymer that exhibits optical performance close to acrylic (PMMA).

The main characteristic of adaptive lenses is to change their shape, and consequently their focal length, by modifying their physical parameters. On the other hand, Fresnel lenses have such features as large aperture, short focal length, they are slim and reduced in size. These kind of lenses have become very popular due to their applications, such as in compound eyes, optical communication systems, photolithography, imaging systems, etc. Nowadays, several kinds of tunable lenses exist such as those made with dielectric materials, lenses that change their focal length by varying the refractive index of the material, liquid lenses composed by elastic membranes and solid elastic lenses. In this work, we present the design, simulation of the mechanical behavior using Finite Element Method (FEM) and cost analysis of an Adaptive Fresnel lens made of an elastic material, together with a mechanical mounting system. Our study considered the use of design thinking methodology to obtain the best optical design at minimal cost. Analysis, results and future applications are presented.

Nowadays, the development of the space apparatus with high optical characteristics still stays the important task. The simplest systems which can provide the required characteristics for remote monitoring from the space are the three-mirror systems. It can be shown that in many cases, classical three-mirror systems have critical value of obscuration that leads to decreasing of resolution. Using off-axis field of view in the systems provides the way to avoid the obscuration influence. We present a technique for designing the three-mirror telescope objectives based on the systems with axial symmetry with an off-axis field of view.
