Optical tables
-
The primary goal of a well designed optical table is to eliminate relative motion between components of test system located on the surface of the optical table because such motion can generate measurement errors.

Image Intensifiers
-
Image intensifier tubes (IITs) are vacuum tubes that amplify a low light-level image to observable levels. Image intensifier tubes are the most important modules of night vision devices that play crucial role in defense/security/industrial applications.Technology of manufacturing of image intensifier tubes is very difficult and performance parameters of modern IITs varies even within the same technological process. Next, test report offered by manufacturers cannot be fully trusted because there are some differences in test methods used by different manufactures. Further on, there are literature sources presenting conflicting claims of different manufacturers. It is quite common to find on the world market two night vision devices (or two image intensifier tubes) of the same data sheet parameters but of totally different image quality. Inverse situation is possible, too. Due to reasons mentioned above testing image intensifier tubes is of critical importance for both their manufacturers, manufacturers of night vision devices (NVDs) and final users of NVDs.

Light Sources
-
There are many low cost artificial light sources used for illumination or for industrial applications: tungsten or halogen bulbs, fluorescent lamps, LED lamps etc. Some of these sources have regulated intensity of emitted light. However, there very few calibrated light sources of precisely known parameters. A light source can be considered as calibrated when its user can precisely regulate its photometric/radiometric parameters like luminance (or illuminance), radiance (or irradiance) at defined spectrum of interest. Such light sources are needed in many applications among them, in systems for testing night vision devices, VIS-NIR cameras and SWIR imagers. Inframet offers a series of calibrated light sources that can be divides into three groups:

Laser Systems
-
Laser systems (laser range finders, laser designators, laser receivers, laser trackers, laser pointers) are one of crucial technologies for defense/security sector. Laser systems have also found mass applications outside defense sector. Testing laser systems is needed for both manufacturers, maintenance workshops and final users for a set of different and important reasons. Hi-tech test equipment can help significantly in manufacturing, maintenance, training, purchase optimization, and optimal use of night vision devices.

Collimators
-
Collimators are optical systems used to imitate standard targets placed in "optical infinity" (very long distance). The collimators are used for projection of image of reference targets into direction of tested imagers. According to type of optical elements used in design, collimators are divided into two groups: reflective collimators and refractive collimators. Reflective collimators due to their wide spectral range are almost exclusively used in systems for testing thermal imagers and are also preferable in systems testing TV cameras, SWIR imagers, laser systems or multi-sensor surveillance systems. Refractive collimators are mostly used in systems for testing night vision devices or TV cameras working in visible/near infrared range.

Multi-Sensor Systems
-
Multi- sensor surveillance systems represent a fast growing group of electro-optical systems of critical importance in both defense and civilian applications. At the same time they are the most expensive groups of electro-optical systems. Most advanced but rarely met multi-sensor surveillance systems are built from a long series of sensors like thermal imager (or two thermal imagers, color VIS camera, low light VIS-NIR camera, SWIR camera, laser range finder, laser designator, laser pointer, illuminator located on a stabilized platform and such systems. Simpler systems built from two-three sensors located on smaller stabilized or non-stabilized platforms are more common.

Optical Systems
-
Optical systems like optical objectives or oculars are a crucial block of modern electro-optical systems. Performance of these systems is often limited by parameters of optical block. Superior optics can significantly increase surveillance ranges of electro-optical surveillance systems like thermal imagers, VIS-NIR cameras, SWIR cameras, and night vision devices. Optical systems in form of optical sights are also used as independent systems in surveillance technology.

THz Cameras
-
Passive THz imagers are capable to see thru thin obstacles and are a very interesting solutions for short distance surveillance applications like airport screening, prison screening etc. Ability to create images of targets hidden by humans under clothes is particularly interesting. This ability can be evaluated when a set of parameters of these imagers is measured and known.

Blackbodies
-
Blackbodies are devices that work as near perfect emitters of thermal radiation in range from visible to microwaves. There are many blackbodies available on international market. Inframet specializes in high-tech expensive blackbodies optimized for narrow market of high requirements. All blackbodies offered by Inframet are characterized by special features.

SWIR Imagers
-
SWIR imagers (short wavelength infrared) are an important group of surveillance electro-optical imagers due several reasons. First, advances in InGaAs technology enabled design of relatively low cost SWIR imagers. Second, InGaAs imagers are very sensitive and can generate images of observed scenery even at dark nights. Third, SWIR imagers are less vulnerable to bad atmospheric conditions than TV/LLLTV cameras working in visible/near infrared band. Fourth, SWIR imagers can generate hi-res images even if they are built using much smaller optics than used for design of thermal imagers.

Streak Tubes
-
Streak tubes are the most important modules of streak cameras used for the study of ultra fast optical phenomena. The latter cameras are tools of critical importance in many areas of science and technology like studies of plasma/electric discharge/ combustion/laser ablation/ condensed matter phenomenon, in optical communications, electron beam acceleration technology, photochemistry, medicine, biology etc. Streak cameras have made possible a series of important scientific discoveries in earlier mentioned areas of science and technology. Precision information about parameters of streak tubes is needed both by manufacturer of such tubes in improve tube design and by users of these tubes to correct data generated by the tubes and make possible more accurate interpretation of output images.

VIS-NIR Cameras
-
Surveillance cameras based on CCD/CMOS/ ICCD/ EMCCD/EBAPS imaging sensors sensitive in visible and near infrared range are widely used in many long range surveillance applications as independent imagers or as part of a bigger multi-sensor surveillance systems. Majority of VIS-NIR cameras are used for day level applications but an increasing number of these cameras is used to enable surveillance in both night and day conditions. In both cases it is important to verify performance of these cameras under varying illumination conditions from very dark nights to ultra bright days. Important missions can fail due to too low sensitivity of VIS-NIR cameras at night conditions (dark, noisy images) or due to too low dynamic at ultra bright day conditions (saturated, blurred images). Next, it is important to use VIS-NIR cameras that generate high quality images in order to achieve maximal effective surveillance ranges.

Rotary wheels
-
Rotary wheels are one of basic blocks of systems for testing imaging EO systems. They are needed to enable motorized exchange of active target at collimator focal plane. There are usually 8 holes in the wheel for targets (other numbers are also possible). Wheels are covered with a black high emissivity coating (emissivity at least 0.97).

Fused Imagers
-
Fused imagers (fusion multi-sensor imaging systems) offer increased surveillance capabilities due to fusion of classical thermal image with classical visible image. The fusion systems are typically built by combining optically images from thermal imager and classical night vision device, or by combining digitally images from thermal imager and digital night vision devices (or electronic VIS-NIR camera).
