六硼化镧灯丝(电镜用品) 性能参数:
| 标准尖Standard Tips | 平尖Flat Tips | 尖尖Sharp Tips |
Brightness | About 10 times that of tungsten, | About 5 times that of tungsten, | Twice as bright as standard tips |
Saturation | Mono spot at about 1,500°C. | Mono spot at about 1,400°C | Almost the same as standard tips |
Crossover | Small (7-10µ) | Large (11-13µ) | Small (7-10µ) |
Angular distribution | Sharp1.6 x10-2 rad | Broad, 3.3-4.2x10-2 rad | Sharp1.6 x10-2 rad |
Used Temperature | Low temperature | Low temperature | High temperature. |
Lifetime | Long life but shorter than flat tips. | Long life; usable at low temperatures and crystallized end changes slowly. | Short |
Operation | Not so difficult. | Easy; thanks to its large spot size and broad adjusting range. | Difficult; Point adjustment needed! |
Stability | High | High; vulnerable to thermal expansion or vibration. | Middle;. Vulnerable to the thermal expansion or vibration. Adjustment is sometimes necessary. |
Technology Needed | High | Ordinary | Very high |
