Description
本発明は、一般に、放射伝送技術の分野に属し、UV放射を標的部位にガイドする方法及び装置に関する。本発明は、例えば、液体を容器に無菌的に充填する、種々の光化学的処理に使用し得る。
深UV領域及び電磁気スペクトルの他の領域(UVA、UVB,UVC、VIS、NIR、IR)で動作し得る光学装置は、ここ数年関心が払われてきた。従来技術における利用可能な光学機器のほとんどは、大エネルギー及び、高出力ビームを水、空気又は液体とガスとを組み合わせて冷却することに関連した熱力学的応力に抵抗し得ない。多くのガスが試され、広範な種類の高純度溶融石英は、深UV光の伝送に利用し得る。しかしながら、これらの成分は、高価で、伝送し得るエネルギーレベルに制約がある。さらに、市販の材料の加工、リソグラフィー及び化学的に誘導される写真にしばしば必要とされるエネルギーレベルを伝送する石英の種類及び合成ガラス成分の能力に関して、空間的な制約及び障害に対する閾値の制約は、厳密な限定を伴う。特に、UV反射性コーティングの製造に関する厳密な制約は、本技術分野の伸展を妨害しており、多くの空間的処理は、クオーツ7(quartz 7)、高価な光学グレードのポリマー及び水晶でのみ可能とされるのみであって、これらの全ては、VIS、NIR、IRでのみ視覚可能なその他のスペクトル領域(例えば、電気通信やIT)における光ビームの処理及びマニピュレーションに主として使用される。
本発明は、流動する液体光ガイドを精製する目的で、液体媒体を光と組み合わせる新規の方法を開示する。
(a)所定の流率の液体流を標的部位を有する接点へと供する工程;
(b)出力、波長、デューティーサイクル及び繰返し率に関して所定のパラメーターを有するUV放射を供する工程;
(c)前記液体流の軌道に沿った該液体流内の前記UV放射を検知する工程;及び
(d)一定時間、前記の化学的又は機械的特性の少なくとも一方に影響を与えるのに十分な条件で、前記液体流を前記標的部位に接するように保持する工程;
を有する。
(a)処理の開始に効果的に選択された波長、強度及び持続時間を有する少なくとも一つの光ビームを生成する工程;
(b)所定の発射位置、軌道及び標的部位を有する、パイプで送られない、液体を伝送する光ジェット流の少なくとも1つを形成するステップであって、前記液体は、前記ジェットの周囲の屈折率(N2)よりも大きな屈折率(N1)を有する、ステップ;並びに
(c)前記光ビームが前記標的部位に向かう軌道に沿って固定された前記ジェットの全体をガイドされるように、前記光ビームを前記ジェットに向ける工程;
を有し、これらにより、前記発射位置と前記標的部位との間でガイドされた前記ビームにより前記の処理を可能とする。

光化学は、近赤外線ではほとんど起こらない。980nm以上の波長で太陽エネルギーを保存し得るいくつかの光化学微生物を除くと、緑色植物や藻類における光合成に関して、可視光は完全に活性である。また、多くの色素は、それ自体で光化学変換反応を開始可能であり、且つ、他の分子における反応に感光的である。光化学における多くの知見に含まれるのは、紫外領域である。3つのサブ領域(UVA、UVB、UVC)への分類は、紫外光に対する人間の皮膚の感受性に関連する。UVA領域は、皮膚に日焼けを惹き起こす。UVB領域は、タンパク、RNA及びDNAに吸収されるので、非常に危険であり、細胞の突然変異及び/又は細胞死を惹起し得る。UVC領域は、微生物及びウィルスの不活化に非常に効果があるので、しばしば「殺菌領域」と称される。真空の紫外領域は、ほぼ全ての物質(水及び空気を含む)に吸収される。従って、真空状態において伝送される。VUV光子の吸収は、1つ以上の結合を切断する。しかしながら、561.6nm未満の波長を有する光子がH2O2分子の分解が可能であるが、H2O2は、300nm以下となるまで紫外光の吸収を開始しないので、この波長領域では光分解又はタンパク分解は、起こらない。このことは、光化学の第1法則を示しており;いわゆる、光の光子が吸収されない場合、光化学反応は起こり得ないことを意味する。
本発明を理解し、且つ、実際にどのように実施するかを理解するため、以下に、非限定的な例として、添付した図面とともに、好適実施例に関して述べる。
本発明は、リアルタイムで流動する導波路又は光化学性を生成する新規の方法を開示する。図1を参照すると、UVジェット流を発生する水射出手段からパルス状UVA、UVB、UVCをガイドするためのリアルタイムで流動する液体導波路を示す本発明による装置100を概略的に示す。装置100は、第1及び第2インレットポート2及び4並びにアウトレット14を有するUVJET水射出手段1の長手中空体と;プレパイプ部分6によりボディー1から射出するように且つ導管5及びこの導管の外部のボディーの領域から来る物質が互いに合流するボディー1内の領域9を規定するように、ボディー1に導入された中空導管5(空気又はガスの全体)と;を備える。インレット2は、適切なリム外径(例えば、5ガロンの容器のインレット/アウトレットよりも小さな外径)を有し装置100に向かう方向7のレーザー装置(図示せず)から伝播するレーザービーム8(UV放射)を受ける機能を有する。ここで、上述のレーザービームは、出力パワーの86%を有する径のレーザーの出力であるとする。レーザー4は、水(若しくは他の液体又は液体とガスとの組み合わせ)を注入する機能を有する。ボディー1の領域9において、上述のUV放射は、上述の水流にカップリングされ、このUVJET流は、ボディー1からアウトレット14を介して出力される。水アウトレット4は、パルス状の光レーザービームが上述のUVJETにカップリングされるベンチュリ圧を形成するように上述のジェット長にさらに沿って配置される。上述のパルス状のレーザーUV放射は、パルス当たり1mJ〜1Jsのエネルギーを有する。このレーザー放射は、好ましくは、約277nmの波長を有し、上述の流動する液体導波アウトレットに正確に到達し従って上述の流動するジェット流にラウンチされるように、伝送され、射出され、或いはガイドされる。一度水が上述のジェットインレットにおいてベンチュリ圧力を適切に形成してポンピングされ、ジェットから水が漏れることがなくなると、このレーザービームは、上述のガイドするプレパイプに喀ぷんリングされ、このジェット流は、UVJETボディーを出力されるにつれ到達し、従って、周囲の空気の屈折率(1.00)よりも(リアルタイムで)流動する水の屈折率よりも高い屈折率を有することに起因して、流動する液体導波路を形成する。従って、装置100のアウトレット3は、空気中で流動する水UVJET流となる。
(ii)UV無しで水ジェットの洗浄サイクルにより処理;
(iii)UVを伴った水ジェットの洗浄サイクルにより処理。
