六硼化镧灯丝（LaB6Cathodes）标准DenkaM-3型六硼化镧灯丝StandardDenkaModel3LaB6Cathodes，在SEM、TEM、X-Ray、ElectronBeamLithography等领域应用，六硼化镧都是***佳的阴极材料。特征：低干扰熔点高、热稳定性好低蒸发压，减少材料损失化学性质稳定亮度高，10倍于钨丝亮度，DenkaM-3初始亮度值1x106A/cm2。寿命长，温度和真空决定灯丝的使用寿命。在1550°C和10-7Torr时，M-3的使用寿命在500小时。安装方便标准灯丝一般有三种形状：标准尖StandardTips，也即90°圆锥体/圆尖，，半径15µ。平尖Flat(Truncated)Tips，圆锥体截去顶端。平尖是优先选择的，稳定性和使用寿命是我们的主要考虑因素，亮度有时需要做出一点牺牲。平尖有两种角度的椎体90°和60°，多种半径尺寸可供选择。尖尖SharpTips，也即60°圆锥体/圆尖，半径有5µ和10µ，当需要很高的初始亮度而使用寿命暂不考虑时，尖尖就是***佳选择。性能参数：标准尖StandardTips平尖FlatTips尖尖SharpTipsBrightnessAbout10timesthatoftungsten,1x106A/cm2·StrAbout5timesthatoftungsten,2-5x105A/cm2·StrTwiceasbrightasstandardtips2x106A/cm2·StrSaturationMonospotatabout1,500°C.Monospotatabout1,400°CAlmostthesameasstandardtipsCrossover***all(7-10µ)Large(11-13µ)***all(7-10µ)AngulardistributionSharp1.6x10-2radBroad,3.3-4.2x10-2radSharp1.6x10-2radUsedTemperatureLowtemperatureLowtemperatureHightemperature.LifetimeLonglifebutshorterthanflattips.Longlife;usableatlowtemperaturesandcrystallizedendchangesslowly.ShortOperationNotsodifficult.Easy;thankstoitslargespotsizeandbroadadjustingrange.Difficult;Pointadjustmentneeded!StabilityHighHigh;vulnerabletothermalexpansionorvibration.Middle;.Vulnerabletothethermalexpansionorvibration.Adjustmentissometimesnecessary.TechnologyNeededHighOrdinaryVeryhigh订购信息：货号产品描述规格80900-05DenkaM-3LaB6StandardforJEOL60-5UM个80900-10DenkaM-3LaB6StandardforJEOL60-10UM个80900-11DenkaM-3LaB6StandardforJEOL90-20UM个80900-20DenkaM-3LaB6StandardforJEOL60-20UM个80900-21DenkaM-3LaB6StandardforJEOL90-21UM个80900-40DenkaM-3LaB6StandardforJEOL60--40UM个80900-41DenkaM-3LaB6StandardforJEOL90-41UM个80900-60DenkaM-3LaB6StandardforJEOL60-60UM个80900-61DenkaM-3LaB6StandardforJEOL90-60UM个80900-80DenkaM-3LaB6StandardforJEOL60-80UM个80900-100DenkaM-3LaB6StandardforJEOL60-100UM个80900-101DenkaM-3LaB6StandardforJEOL90-100UM个80900-05DenkaM-3LaB6StandardforJEOLJEOL60-5UM个80904-5DenkaM-3LaB6StandardforKFSHARP60-5UM个80904-10DenkaM-3LaB6StandardforKFSHARP60-10UM个80904-20DenkaM-3LaB6StandardforKFFLATTIP60-20UM个80904-21DenkaM-3LaB6StandardforKFFLATTIP90-20UM个80904-40DenkaM-3LaB6StandardforKFFLATTIP60-40UM个80904-41DenkaM-3LaB6StandardforKFFLATTIP90-40UM个80904-60DenkaM-3LaB6StandardforKFFLATTIP60-60UM个80904-61DenkaM-3LaB6StandardforKFFLATTIP90--60UM个80904-80DenkaM-3LaB6StandardforKFFLATTIP60-80UM个80904-81DenkaM-3LaB6StandardforKFFLATTIP90-80UM个80904-100DenkaM-3LaB6StandardforKFFLATTIP60-100UM个80904-101DenkaM-3LaB6StandardforKFFLATTIP90-100UM个80906-5DenkaM-3LaB6StandardforCAMBRIDGE60-5UM个80906-10DenkaM-3LaB6StandardforCAMBRIDGE60-10UM个80906-11DenkaM-3LaB6StandardforCAMBRIDGE90-20UM个80906-20DenkaM-3LaB6StandardforCAMBRIDGE60-20UM个80906-21DenkaM-3LaB6StandardforCAMBRIDGE90-40UM个80906-40DenkaM-3LaB6StandardforCAMBRIDGE60-40UM个80906-41DenkaM-3LaB6StandardforCAMBRIDGE90-60UM个80906-60DenkaM-3LaB6StandardforCAMBRIDGE60-60UM个80906-61DenkaM-3LaB6StandardforCAMBRIDGE90-80UM个80906-80DenkaM-3LaB6StandardforCAMBRIDGE60-80UM个80906-81DenkaM-3LaB6StandardforCAMBRIDGE60-100UM个80906-100DenkaM-3LaB6StandardforCAMBRIDGE60-100UM个80908-5DenkaM-3LaB6StandardforHITACHI60-5UM个80908-10DENKAM3-H2LAB6FORHITACH60-10UM个80908-11DENKAM3-H2LAB6FORHTIACHI90-20UM个80908-20DENKAM3-H2LAB6FORHITACHI60-20UM个80908-21DENKAM3-H2LAB6FORHITACHI90-40UM个809098-40DENKAM3-H2LAB6FORHITACHI60-40UM个80908-41DENKAM3-H2LAB6FORHITACHI90-60UM个80908-60DENKAM3-H6LAB6FORHITACHI60-60UM个80908-61DENKAM3-H2LAB6FORHITACHI90-60UM个80908-80DENKAM3-H6LAB6FORHITACHI60-80UM个80908-81DENKAM3-H2LAB6FORHITACHI90-100UM个80908-100DENKAM3-H6LAB6FORHITACHI60-100UM个80908-10DENKAM3-H2LAB6FORHITACH60-10UM个)
