Infrared optical systems require a range of exotic materials, many with large indices of refraction. The mismatch in the index between the optical element and the surrounding medium can result in reflection losses that approach 50%. Antireflection (AR) coatings are applied to these elements in order to minimize "ghost" reflections and improve the optical transmission through a system. The coatings are designed to be highly transparent;however, significant infrared absorption has been observed in some AR coatings. Likely candidates for the loss mechanism are water trapped into the optical coatings during deposition and water being incorporated into coating voids or grain boundaries during exposure to ambient humidity. Five different AR coatings have been procured from four manufacturers to study the cause of the observed losses. Upon receipt of the coated samples, infrared transmission measurements were made which showed the presence of incorporated water/hydroxyl, as evidenced by reduced transmission around 2.9 mu m. Four of the five sample types placed in laboratory air for two months continued to absorb water, whereas those placed in flowing dry nitrogen showed no change. Samples placed in a humid environment for one, three and ten days also showed additional water incorporation with the magnitude of the change in transmission on the order of that observed with the two-month air exposure.

Alumina-doped zinc oxide (AZO) films have wide range of applications in optical and optoelectronic devices. AZO films have advantage in high transparency, high stability to hydrogen plasma and low cost to alternative ITO film. AZO film was prepared by direct-current (DC) magnetron sputtering from ceramic ZnO:Al2O3 target. The AZO films were compared in two different conditions. The first is substrate heating process, in which AZO film was deposited by different substrate temperature, room temperature, 150 degrees C and 250 degrees C. The second is vacuum annealing process, in which AZO film with deposited at room temperature have been annealed at 250 degrees C and 450 degrees C in vacuum. The optical properties, electrical properties, grain size and surface structure properties of the films were studied by UV-VIS-NIR spectrophotometer, Hall effect measurement equipment, x-ray diffraction, and scanning electron microscopy. The resistivity, carrier mobility, carrier concentration, and grain size of AZO films were 1.92x10(-3) Omega-cm, 6.38 cm(2)/Vs, 5.08x10(20) #/cm(3), and 31.48 nm respectively, in vacuum annealing of 450 degrees C. The resistivity, carrier mobility, carrier concentration, and grain size of AZO films were 8.72x10(-4) Omega-cm, 6.32 cm(2)/Vs, 1.13x10(21) #/cm(3), and 31.56 nm, respectively, when substrate temperature was at 250 degrees C. Substrate heating process is better than vacuum annealed process for AZO film deposited by DC Magnetron Sputtering.

To simulate solar radiation at the earth's surface, a new economical multiple-lamp solar simulator was designed. The solar simulator is comprised of 188 reflector sunlight dysprosium lamps whose light spectrum is very similar to air mass 1.5 (AM1.5) solar spectrum terrestrial standards. Lamps are configured in a hexagonal pattern with 15 columns of 12 or 13 lamps at a lamp-to-lamp spacing and column-to-column spacing of 295mm. Without altering the radiation spectral distribution, the average irradiance on target irradiated area can be adjusted over a wide range between 150 and 1100W/m(2) by means of the variation of lamps number or/and lamp-to-irradiated area distance. At the height of 2.0m the solar simulator provides 2mx1.5m irradiated area with over 1000 W/m(2). Measurement of irradiance indicates that the multiple-lamp simulator conforms to Class B of ASTM (American Society for Testing and Materials) Standard (ASTM E927-2005) in regard to spectrum match, irradiance uniformity and stability. To enlarge the effective irradiated area, two large mirror-like stainless steel plates was mounted on both of the long sides of the solar simulator. The radiation characteristics of simulator are improved and the optimized effectively irradiation surface is expanded up to 81.6%.

In this paper, we report on current developments aimed at improving the focusability of the Texas Petawatt Laser. Two major campaigns have been commissioned that address the issue of focusability. First, we implemented a closed loop, 32 actuator bi-moprh deformable mirror (DFM) to compensate for aberrations in the optical train and second, a color corrector lens assembly was installed that compensates for chromatic errors accumulated in broadband (>15 nm), large aperture (> 20 cm) laser systems. We will present in detail, pre and post correction results with the DFM and describe challenges faced when one activates a single shot, high energy closed loop system. Secondly, we will provide modeling and experimental results of our color correction system. This is a novel approach to a problem only seen in high energy, broadband, large aperture laser pulses. By using color correction optics we have demonstrated a 6X increase in focal intensity. With the installation of the DFM, the rms wavefront error in the system was reduced from 2.4 waves to. 131 waves, further increasing intensities seen at focus by 1 order of magnitude.

In this paper, we propose and demonstrate a novel design to make color mixing and projection of RGB LEDs. The optical elements include a high reflective light pipe, a volume scattering diffuser and a TIR lens. The system optical efficiency is around 46 % while the color is well mixing for the cases at the CCTs of 6500K, 4500K and 3000K.

The Fine Guidance Sensor (FGS) is part of the science instrumentation for the James Webb Space Telescope (JWST). The FGS is required to operate at 37 K and provide the data needed to facilitate fine pointing and attitude stabilization necessary to meet the requirements of the mission's science and engineering operations. We describe here the selection of the proper optical design form to meet requirements and its relative merits. The FGS has progressed with the successful completion of several key design reviews. The optical design of the current stage will be discussed here in detail.

Recently in the micro-optical engineering area has been a grown in use of tunable liquid lenses because this lenses us allow versatility in the focusing range, also an easy handling and implementation. In the literature, many tunable lens models have been reported, but most of this work has been on describing the optical quality of the images, the opto-mechanical analysis is neglected. In this paper, an analysis of opto-mechanical of a tunable liquid lens is presented, for this;we show a finite element simulation of mechanical behavior and estimate how this influences in the optical performance of the lens. The liquid lens is composed of two elastic transparent membranes and of a cylindrical metallic mount.
