LS-450LED光源
| LS-450藍(lán)色脈沖光源為L(zhǎng)ED,產(chǎn)生脈沖或連續(xù)輸出470 nm--藍(lán)色區(qū)域-用于熒光測(cè)量。該光源設(shè)計(jì)為與Ocean Optics 光譜儀一起用于熒光測(cè)量,帶FOXY光纖氧傳感器 ,和取樣光學(xué)件如CUV-UV-ALL 4-way 試管固定器。 |
特點(diǎn)
-
激勵(lì)電源。用于高靈敏度的熒光測(cè)量,產(chǎn)生脈沖或連續(xù)輸出470 nm。
-
軟件選擇。通過(guò)手動(dòng)或軟件操作控制燈泡的開(kāi)關(guān),用于脈沖或連續(xù)模式。
-
同時(shí)探測(cè)器掃描速度。通過(guò)等或光譜儀上的模塊構(gòu)成燈泡脈沖速率。
LS-450通過(guò)手動(dòng)或軟件操作控制燈泡的開(kāi)關(guān),用于脈沖或連續(xù)模式。也可與LS-450一起為其它特殊LED波長(zhǎng)(見(jiàn)下) 使用。
LS-450單機(jī)版
通過(guò)一個(gè)界面電纜LS-450與光譜儀連接,使用了SMA905連接器。你能通過(guò)光源或S2000光譜儀的電路板上的跳動(dòng)模塊配置操作電源。
也可為L(zhǎng)S-475脈沖藍(lán)色LED, 以其波長(zhǎng)和電扇冷卻為特征(475 nm)
機(jī)架固定版
R-LS-450藍(lán)色LED為L(zhǎng)S-450的機(jī)架固定版。對(duì)于限制桌面或架盒空間的多個(gè)LED使用者,R-LS-450-2 (2 LEDs)機(jī)架固定版為另一個(gè)選擇。你能通過(guò)R-LS-450電路板上的動(dòng)模塊配置R-LS-450和R-LS-450-2操作。
另外。LS-450 可安裝在SF2000 光譜儀上。LS-450裝在一張卡上,與光譜儀裝在同一個(gè)盒中。
LS-450與USB2000光譜儀一起使用
通過(guò)光譜儀的 10-pin 連接器,USB-LS-450 模塊與 USB2000光譜儀連接在一起。光譜儀提供LED能量也保證了同樣的功能和I2C通信。通過(guò)增加一個(gè)取樣光學(xué) 元件和與筆記本電腦連接的界面。SB2000-with-USB-LS-450 提供了一個(gè)便利的,便攜的系統(tǒng)。
對(duì)FOXY使用者有利
USB-LS-450 內(nèi)嵌了24-bit模擬數(shù)字轉(zhuǎn)換器,構(gòu)成了一個(gè)100 ohm platinum RTD。USB-LS-450抯可存儲(chǔ)溫度和氧校準(zhǔn)系數(shù)。
