integrating sphere meaning in Hindi

Examples

1. Integrating spheres vary in size from a few centimeters in diameter up to a few meters in diameter.
2. If absorption differences are a concern, absorption can be measured with the use of an integrating sphere.
3. Due to the many scatterings this effect is much more pronounced in an integrating sphere than for materials irradiated normally.
4. The practical implementation of the integrating sphere was due to work by R . Ulbricht ( 1849 1923 ), published in 1900.
5. Initial light output is measured with an integrating sphere photometer, 30 seconds after the light is switched on with fresh ( or newly charged ) batteries.
6. Light from the exit slit is passed either through diffusers or an integrating sphere on to the imaging device while a calibrated detector simultaneously measures the light.
7. For example, to take UV measurements, quartz rather than glass lenses, optical fibers, Teflon diffusers, and barium sulphate coated integrating spheres are often used to ensure accurate UV measurement.
8. Since all the light incident on the input port is collected, a detector connected to an integrating sphere can accurately measure the sum of all the ambient light incident on a small circular aperture.
9. A collimated beam of light from a light source ( ASTM D1003-Illuminant C, BS EN ISO 13468 Parts 1 and 2-Illuminant D65 ) passes through a sample mounted on the entrance port of an integrating sphere.
10. In 1965 Wyszecki developed the seven-field colorimeter with which an observer can view with both eyes one or more of seven hexagonal fields, each with separately controllable RGB sources achieved with filtered light, mixed in an integrating sphere.
