Ecoptik Optical Dome Features and Advantages

Two surfaces that are almost perfectly parallel

1.To ensure that the two surfaces are absolutely parallel, the eccentricity tolerance and radius of curvature tolerance must be very well controlled.

2.The current DOME parallel tolerance of ECOPTIK is < <±2μm.

High precision surface accuracy ensures  imaging without distortion

1. Although limited by the spherical shape, the overall surface fringe cannot be measured at present, ECOPTIK tries its best to improve each local surface fringe within the detectable range.

2. At present, the ECOPTIK dome local surface accuracy can reach λ/10

Unique hype-hemispheric processing  capability

1. The super-hemisphere is the part of the height beyond the spherical core, and ECOPTIK has a practical patent for the process.

2. The maximum range can exceed the radius by 3mm.

Optical Dome Applications

In the optical field, the application of an optical dome lens is mainly divided into two categories, one is military manufacturing and the other is ordinary optical systems.

• Military manufacturing mainly refers to the infrared dome, mainly ZnSe and sapphire materials.

• An optical system, mainly used for imaging and detection measurement system. It is mainly used for deep-sea imaging in imaging. The glass material can withstand sufficient water pressure and does not deform due to the acrylic material. Furthermore, the light transmittance of glass, the bubbles and stripes of the material itself, and the smoothness and hardness of the surface of the material itself make more deep-sea exploration keen to choose the glass material dome. Also used for atmospheric detection, pyranometer. The two almost parallel surfaces prevent the light from being significantly refracted when passing through the component, thereby ensuring that energy is not lost and improving the accuracy of the measurement.

• Meteorological monitoring: A device that collects sunlight in a total solar radiometer. The nearly absolute parallel design makes no refraction loss of light, perfect record of the radiation data of sunlight.

• Observation to space: Dome in all-sky camera is designed to provide high quality sky images for weather and meteor observations. The purpose of these systems is to carry out All of Full Sky (180°x180°) surveillance of the night or day sky, and in a continuous fashion. It is possible to assess, in real time, the night sky quality, and to record fast phenomena (meteors and fireballs) or slower (satellites, rockets, noctilucent clouds, zodiacal light, aurora, airglow ....).
