微型 BLM2-D系列-寬帶雙SLD光源模塊是強(qiáng)大的和非常寛帶寬的光源，它是基于兩個(gè)有略微差別中心波長(zhǎng)的SLD的結(jié)合構(gòu)成。 這些穩(wěn)定、可靠、低噪聲的模塊擴(kuò)展了D-系列臺(tái)式SLD寬帶光源的生產(chǎn)線，容許容易地集成成客戶系統(tǒng)，尤其是OEM的應(yīng)用。微型BLM2-D系列是OCT和生物醫(yī)學(xué)成像、布拉格光柵和其它種類光學(xué)傳感以及要求寬光譜和非常短的相干長(zhǎng)度的微型強(qiáng)光源模塊的大量其它應(yīng)用的理想光源。
內(nèi)置微型雙通道SLD電流和溫度控制器容許由前面板按鈕、外部TTL或經(jīng)RS-232接口的PC接通或斷開SLD。
雖然為了獲得光譜寬度和輸出功率的最好結(jié)合每個(gè)SLD的工作參數(shù)是預(yù)先設(shè)定的，但本公司可以根據(jù)要求提供一個(gè)密碼鑰匙容許經(jīng)RS-232接口改變SLD的參數(shù)。
BLM2-D模塊基板的特征是把安裝設(shè)置納入其中，從基板延伸。這些安裝設(shè)置容許容易固定 BLM2-D光源模塊到一個(gè)熱沉上，獲得最寬的可能的環(huán)境工作范圍。不用熱沉使用BLM2-D光源模塊也是可能的，然而這將限定最大環(huán)境工作溫度到+40°C。
這個(gè)技術(shù)說明描述了本公司提供的標(biāo)準(zhǔn)模塊。無論如何，這個(gè)靈活的光源設(shè)計(jì)和大量一體化有效的不同的SLD模塊容許設(shè)計(jì)大量定制的光源，包括雙波長(zhǎng)光源，其中具有不重疊光譜不同譜帶的SLD被結(jié)合在一起。

1 Light source modules must be fixed onto an appropriate heatsink for getting a widest possible operating temperature range. However, it is also possible to use
BLM2-D without a heatsink, although in a limited range of ambient temperatures. The highest operating temperature without heatsinking is +40 °C in case of a free
air circulation around the package.
2 DC power supply should be capable to produce up to 3.5A. A less powerful power supply may be used, but it will limit the operating temperature range. It is not
allowed to use a power supply with a maximum current of less than 2.0 A.
