LS-450LED光源
|
|
LS-450蓝色脉冲光源为LED，产生脉冲或连续输出470 nm--蓝色区域-用于荧光测量。该光源设计为与Ocean Optics 光谱仪一起用于荧光测量，带FOXY光纤氧传感器 ，和取样光学件如CUV-UV-ALL 4-way 试管固定器。 |
特点
-
激励电源。用于高灵敏度的荧光测量，产生脉冲或连续输出470 nm。
-
软件选择。通过手动或软件操作控制灯泡的开关，用于脉冲或连续模式。
-
同时探测器扫描速度。通过等或光谱仪上的�？楣钩傻婆萋龀逅俾�。
LS-450通过手动或软件操作控制灯泡的开关，用于脉冲或连续模式。也可与LS-450一起为其它特殊LED波长(见下) 使用。
LS-450单机版
通过一个界面电缆LS-450与光谱仪连接，使用了SMA905连接器。你能通过光源或S2000光谱仪的电路板上的跳动�？榕渲貌僮鞯缭�。
也可为LS-475脉冲蓝色LED, 以其波长和电扇冷却为特征（475 nm）
机架固定版
R-LS-450蓝色LED为LS-450的机架固定版。对于限制桌面或架盒空间的多个LED使用者，R-LS-450-2 (2 LEDs)机架固定版为另一个选择。你能通过R-LS-450电路板上的动�？榕渲肦-LS-450和R-LS-450-2操作。
另外。LS-450 可安装在SF2000 光谱仪上。LS-450装在一张卡上，与光谱仪装在同一个盒中。
LS-450与USB2000光谱仪一起使用
通过光谱仪的 10-pin 连接器，USB-LS-450 �？橛� USB2000光谱仪连接在一起。光谱仪提供LED能量也保证了同样的功能和I2C通信。通过增加一个取样光学 元件和与笔记本电脑连接的界面。SB2000-with-USB-LS-450 提供了一个便利的，便携的系统。
对FOXY使用者有利
USB-LS-450 内嵌了24-bit模拟数字转换器，构成了一个100 ohm platinum RTD。USB-LS-450抯可存储温度和氧校准系数。
