紫外线手电筒是一种发出紫外线光谱范围内的光的手电筒。它可用于多种应用,例如识别伪造的文件和查找冰箱中的泄漏。手电筒通常类似于标准手电筒,由发光二极管(LED)和手柄组成。它们可以有多种形式,例如小型手动设计或大型灯笼式模型。

什么是紫外线手电筒

紫外线手电筒是一种发出紫外线光谱范围内的光的手电筒。它可用于多种应用,例如识别伪造的文件和查找冰箱中的泄漏。手电筒通常类似于标准手电筒,由发光二极管(LED)和手柄组成。它们可以有多种形式,例如小型手动设计或大型灯笼式模型。

紫外线(UV光)是指波长小于可见光的光。之所以称为紫外线,是因为紫色是可见光最短波长的颜色。在阳光下发现紫外线。有时也称为黑光。有许多不同类型的紫外线手电筒。手电筒的主体可以由多种材料制成,例如铝或塑料。通常是防水的,大多数紫外线手电筒都使用标准电池。

LED是紫外线手电筒最重要的部分之一。有些型号具有允许在可变输出上发光的设置。这允许用户产生执行任务所需的精确光量。LED通常具有耐冲击性,以提高耐用性。紫外线手电筒折射镜的质量可以决定LED产生的光束的平滑度。LED覆盖的距离通常会有所不同。


紫外线手电具有许多不同的应用。这是照亮光线不足区域的理想工具。夜总会可以使用它们检查顾客的入场盖章。犯罪侦查人员经常使用紫外线手电筒在犯罪现场寻找可能的证据。维修人员通常使用此工具查找暗区设备中的裂缝或泄漏。

这些紫外线设备通常也用于验证文件的真实性。例如,可以使用紫外线手电筒检查带有全息图以防止伪造的物品(例如信用卡)。将光照射到全息图上可以使人们看到已嵌入在全息图中以进行授权的设计。

如果一个人直接注视许多紫外线手电筒可能会很危险,因为这会导致视力受损。将手电筒照在反射镜(例如镜子)上也可能对视力造成危险。过度暴露于紫外线下,皮肤也可能有害,因为过度暴露会破坏维生素A。但是,紫外线手电通常不是问题,但是,由于其通常的用途通常不需要长时间在皮肤上使用。

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.
