Beam expander
| Glossary Of Laser Terminology |
An optical device that increases beam diameter while decreasing beam divergence (spread). in its simplest form, consists of two lenses, the first to diverge the beam and the second to re-collimate it. also called an upcollimator.

Beam angle, английский
If you`re into reading light-performance data, beam angle is the point at which the intensity of a source drops to 50% of maximum (center reading) measured in degrees of the full angle. simply: how wide?
Beam angle (rt), английский

Divergence, английский
- (дивергенция, расхождение) ситуация, в которой два или больше графиков дают расхождение в подтверждениях тенденций на рынке. например, ценовой график образует новый пик, по абсолютному значению превышающий предыдущий, но оцсцилятор этого не подтверждает.
- Дивергенция, расхождение [нарастание] колебаний; колебательная неустойчивость
- Дивергенция, т. е. ситуация, в которой два или больше графиков индексов дают расхождение с ценовым графиком.
- The angular measurement of laser beam spread with distance. the projected dot of a laser will increase in size the farther it is projected. laser divergence is measured in milliradians (mrad). dosimetry
- 1. a condition in which one eye points directly at the object of interest but the other does not 2. the process of moving apart to follow different courses 3. the amount of difference between two quantities, especially where the difference is unexpected 4. a deviation from a typical behaviour pattern or expressed wish

- Расхождение; отклонение; геод. невязка
- A horizontal outflow of air.
- When two or more averages or indexes fail to show confirming trends.
- Term sometimes used to describe the spreading of ultrasonic waves beyond the near field. it is a function of transducer diameter and wavelength in the medium. see beam spread.

Beam splitter, английский
An optical device used to divide the light from a laser into two separate beams -the reference beam and the object beam. it consists of a partially transparent mirror that reflects part of the laser beam and transmits the rest.
Failsafe interlock, английский
An interlock where the failure of a single mechanical or electrical component of the interlock will cause the system to go into, or remain in, a safe mode.
