Scattering of rays Rays having long wavelength UV rays having short wavelength are likely to hit atoms and molecules and tend to scatter. Atoms & molecules UV rays having short wavelength Atoms & molecules

Scattering of rays UV rays are short in UV rays wavelength and tend to scatter. Near IR rays (Long wavelength) UV rays (Short wavelength) Scattering Ideal to see surface of objects Easy to see details of surface, objects and scratches

Application examples of UV camera and lens + Surface inspection of circuits and soldering condition: Clearer to detect damage, dust or stain + Manufacturing and quality control of semiconductors: Leaves no damage nor effect on the objects + Usages with microscope in medical applications + Detection of forgery, falsified documents, bills and credit cards:   *Genuine U.S. dollar bill does not emit light *Transparent stamp appears on latest credit card + Inspection of fiber optics + Inspection of oil contamination and leakage

Example 1: LCD display ＵＶ lens Ordinary lens Dust Scratch 電卓兼時計のLCD表示部分です。やはりXC-EU50の方はLCDパネル表面の状態が良く表現されています。 Dust Scratch UV camera: SONY XC-EU50 Std. Camera: SONY XC-ES50 Cordial thanks to SONY Corp.for the image data

Example 2: Fibers ＵＶ lens Ordinary lens 繊維です。XC-EU50の方は繊維の表面状態が優先されるため細かな硬い感じがします。他方XC-ES50の画像は繊維の中まで長波長が入り込んでいるためソフトで細やかさはあまり感じられません。とにかく画像の差は歴然です。この場合、繊維上の不要物（ゴミなど）の検査などに良いかもしれません。 UV camera: SONY XC-EU50 Std. Camera: SONY XC-ES50 Cordial thanks to SONY Corp.for the image data

Example 3: P.C. board UV lens Ordinary lens 実装基板です。基板の配線がXC-EU50では表面のレジスト層で反射され見えず、そのために部品とその半田状態が良好に認識できます。XC-ES50では配線も見え込み入った複雑な画像となっています。 Easy to see on-board parts and soldering conditions. UV camera: SONY XC-EU50 Std. Camera: SONY XC-ES50 Cordial thanks to SONY Corp.for the image data

Example 4: Uneven surface UV lens Ordinary lens UV camera: SONY XC-EU50 Std. Camera: SONY XC-ES50 Cordial thanks to SONY Corp.for the image data

Example 5: Surface layer UV lens Ordinary lens ゴム製の電卓のキー部分です。XC-EU50はゴム表面のゴミが確認できます。 UV camera: SONY XC-EU50 Std. Camera: SONY XC-ES50 Cordial thanks to SONY Corp.for the image data
