LS-450LED光源
|
|
LS-450藍色脈沖光源為LED，產生脈沖或連續輸出470 nm--藍色區域-用于熒光測量。該光源設計為與Ocean Optics 光譜儀一起用于熒光測量，帶FOXY光纖氧傳感器 ，和取樣光學件如CUV-UV-ALL 4-way 試管固定器。 |
特點
-
激勵電源。用于高靈敏度的熒光測量，產生脈沖或連續輸出470 nm。
-
軟件選擇。通過手動或軟件操作控制燈泡的開關，用于脈沖或連續模式。
-
同時探測器掃描速度。通過等或光譜儀上的模塊構成燈泡脈沖速率。
LS-450通過手動或軟件操作控制燈泡的開關，用于脈沖或連續模式。也可與LS-450一起為其它特殊LED波長(見下) 使用。
LS-450單機版
通過一個界面電纜LS-450與光譜儀連接，使用了SMA905連接器。你能通過光源或S2000光譜儀的電路板上的跳動模塊配置操作電源。
也可為LS-475脈沖藍色LED, 以其波長和電扇冷卻為特征（475 nm）
機架固定版
R-LS-450藍色LED為LS-450的機架固定版。對于限制桌面或架盒空間的多個LED使用者，R-LS-450-2 (2 LEDs)機架固定版為另一個選擇。你能通過R-LS-450電路板上的動模塊配置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盒中。
LS-450與USB2000光譜儀一起使用
通過光譜儀的 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。通過增加一個取樣光學 元件和與筆記本電腦連接的界面。SB2000-with-USB-LS-450 提供了一個便利的，便攜的系統。
對FOXY使用者有利
USB-LS-450 內嵌了24-bit模擬數字轉換器，構成了一個100 ohm platinum RTD。USB-LS-450抯可存儲溫度和氧校準系數。
