紫外線手電筒是一種發出紫外線光譜范圍內的光的手電筒。它可用于多種應用,例如識別偽造的文件和查找冰箱中的泄漏。手電筒通常類似于標準手電筒,由發光二極管(LED)和手柄組成。它們可以有多種形式,例如小型手動設計或大型燈籠式模型。

紫外線(UV光)是指波長小于可見光的光。之所以稱為紫外線,是因為紫色是可見光最短波長的顏色。在陽光下發現紫外線。有時也稱為黑光。有許多不同類型的紫外線手電筒。手電筒的主體可以由多種材料制成,例如鋁或塑料。通常是防水的,大多數紫外線手電筒都使用標準電池。

LED是紫外線手電筒最重要的部分之一。有些型號具有允許在可變輸出上發光的設置。這允許用戶產生執行任務所需的精確光量。LED通常具有耐沖擊性,以提高耐用性。紫外線手電筒折射鏡的質量可以決定LED產生的光束的平滑度。LED覆蓋的距離通常會有所不同。


紫外線手電具有許多不同的應用。這是照亮光線不足區域的理想工具。夜總會可以使用它們檢查顧客的入場蓋章。犯罪偵查人員經常使用紫外線手電筒在犯罪現場尋找可能的證據。維修人員通常使用此工具查找暗區設備中的裂縫或泄漏。

這些紫外線設備通常也用于驗證文件的真實性。例如,可以使用紫外線手電筒檢查帶有全息圖以防止偽造的物品(例如信用卡)。將光照射到全息圖上可以使人們看到已嵌入在全息圖中以進行授權的設計。

如果一個人直接注視許多紫外線手電筒可能會很危險,因為這會導致視力受損。將手電筒照在反射鏡(例如鏡子)上也可能對視力造成危險。過度暴露于紫外線下,皮膚也可能有害,因為過度暴露會破壞維生素A。但是,紫外線手電通常不是問題,但是,由于其通常的用途通常不需要長時間在皮膚上使用。

What is an Ultraviolet Flashlight?

An ultraviolet flashlight is a type of flashlight that emits light within the ultraviolet spectrum. It is used in a wide variety of applications, such as identifying forged documents and looking for leaks in refrigerators. The flashlight usually resembles a standard flashlight, and consists of a light emitting diode (LED) and a handle. They can come in various forms, such as small, hand-sized designs or large, lantern-type models.

Ultraviolet light (UV light) refers to light that has a wavelength that is smaller than visible light. It is called ultra violet, because violet is the color of the shortest wavelength of visible light. Ultraviolet light is found in sunlight. It is also sometimes known as black light.

There are many different types of ultraviolet flashlights. The main body of the flashlight can be made from many kinds of materials, such as aluminum or plastic. Usually waterproof, most UV flashlights run on standard batteries.

The LED is one of the most important parts of the ultraviolet flashlight. Some models have settings that allow it to be shone at variable outputs. This allows the user produce the exact amount of light needed to perform a task. The LED is usually impact-resistant, for durability. The quality of the ultraviolet flashlight's refractor can determine the smoothness of the light beam produced by the LED. The distance covered by the LED generally varies.

The ultraviolet flashlight has many different applications. It is an ideal tool to illuminate poorly lit areas. Nightclubs can use them to check admission hand stamps on patrons. Criminal investigators often use UV flashlights to search for possible evidence at a crime scene. Repairmen commonly use this tool to look for cracks or leaks in equipment located in dark areas.

These UV devices are often also used to verify the authenticity of documents. For example, items that feature a hologram to prevent forgeries — such as credit cards — can be examined using an ultraviolet flashlight. Shining the light on the hologram enables one to see a design that has been embedded in the hologram for authorization purposes.

Many ultraviolet flashlights can be dangerous if a person looks directly into them, because this can cause vision damage. Shining the flashlight onto a reflective surface, such as a mirror, can also be dangerous to eyesight. Excessive skin exposure to UV light can also be harmful, as overexposure tends to destroy Vitamin A. This is generally not a problem with UV flashlights, however, as its common applications usually do not require its use on skin for long periods of time.
