Uncooled thermal lens

　　Hertfordshire-based Silent Sentinel has expanded its Aeron Ranger suite of cameras to include a 25-150mm Long Wavelength Infrared (LWIR) uncooled thermal lens, which replaces the 50-150mm lens. This new lens offers crisp images within a rugged housing, the makers say.

　　The new F1.4 lens features a 6x motorised optical zoom as well as a narrow horizontal field of view: 25.4 degrees (W) – 4.1 degrees (T) and is capable of detecting human targets at ranges of over three kilometres and vehicles at a range of ten kilometres.

　　This new lens is part of the Aeron Ranger suite of cameras, a series of compact and ruggedized thermal sensors capable of being deployed in deserts and Arctic coastlines. They can operate within a temperature range of minus 30 degrees C to 65 degrees C and are tested to an IP67 level of environmental protection for performance even in extreme conditions. This means that the Aeron Rangers can withstand the harshest surroundings in challenging applications such as maritime and border security as well as vehicle mount installations, the firm says.

　　The Aeron Ranger’s 360 degrees continuous rotation and rapid pan and tilt speeds mean that it can detect small targets in remote locations and in a variety of climates. Aeron Rangers have previously been deployed on police vehicles in Europe, at airports in the Middle East, and for CNI (critical national infrastructure) applications in North America.

　　Silent Sentinel provides surveillance and security systems, specialising in cooled and uncooled long-range thermal camera platforms. Products have been exported to over 50 countries.

　　James Longcroft, Sales Director at Silent Sentinel said: “The introduction of this new lens illustrates our commitment to keeping the Aeron platform at the cutting edge of threat detection. By incorporating this new lens, we are able to provide a competitively positioned, compact and ruggedized camera that offers best-in-class performance even in brutal conditions. Our expertise lies in combining accuracy and durability to ensure the precise recognition of small targets at long range in challenging environments.”

　　非冷卻熱感鏡頭

　　總部位于Hertfordshire的Silent Sentinel公司擴大了其Aeron Ranger攝像機套件，其包括一個25-150mm長波長紅外(LWIR)非冷卻熱感鏡頭，代替了原來的50-150mm鏡頭。制造商表示，這種新鏡頭具有堅固的外殼保護，可以提供清晰的圖像。

　　新型F1.4鏡頭具有6倍電動光學變焦以及狹窄的水平視野：25.4度(W)– 4.1度(T)，能夠檢測三公里以上范圍內的人體目標以及十公里的范圍車輛目標。

　　這款新鏡頭是Aeron Ranger攝像機套件的一部分，該套件是一系列緊湊而堅固的熱傳感器，能夠部署在沙漠和北極海岸線上。它們可以在負30攝氏度至65攝氏度的溫度范圍內正常運行，并經過IP67環保等級的測試，即使在極端條件下也能保證其性能正常。該公司表示，這意味著Aeron Ranger系列攝像機可以在具有挑戰性的應用中承受最惡劣的環境，例如海上和邊境安全。

　　Aeron Ranger的360度連續旋轉以及快速的平移和傾斜速度意味著它可以檢測偏遠地區和各種氣候中的小型目標。Aeron Rangers先前已部署在歐洲的警車、中東的機場以及北美的CNI(關鍵國家基礎設施)應用中。

　　Silent Sentinel提供監視和安全系統，專門研究冷卻和不冷卻的遠程熱像儀平臺，其產品已出口到50多個國家。

　　Silent Sentinel銷售總監James Longcroft表示：“這種新型鏡頭的推出說明了我們致力于將Aeron平臺保持在威脅檢測最前沿的承諾。通過結合使用這種新鏡頭，我們能夠提供具有競爭力的緊湊而堅固型的攝像機，即使在殘酷的條件下也能提供一流的性能。我們的專長在于將準確性和耐用性相結合，以確保在挑戰性的環境中能夠長期精準識別小型目標。”
