What can blue filters be used for?

Forensic Use

When analyzing a crime scene, a forensics team employs blue light and luminol to expose previously undetectable stains.

Detection of blood, oils, sperm, and saliva begins with the use of blue light. The use of luminol, rather than blue light, is what causes the blood to glow.

Black lights, not blue lights, are typically used to look for biological fluids; nonetheless, the underlying principle is the same. An intense blue/purple light is produced by black lights. As a result, the color blue appears more intense.

To walk through the fog

There is a good reason why most newer cars have standard white and blue headlights in combination. There is no other option when dealing with fog than using blue lights.

Fog is common in hunting locations with lots of open space, but it’s rare to get stranded in it so dense that it’s impossible to see. You can use a blue flashlight filter to see better if you have to go through fog.

Reading in the Dark

Using a blue light rather than a red or brilliant white light makes it easier to see small prints and handle small things.

While it won’t be quite the same brightness as a green light, the light will be considerably clearer than red and won’t strain your eyes as much as a powerful white light.

Because you only need 30 lumens of light to read, a dazzling white flashlight is frequently too powerful.

For Night Vision

Blue light is better than white light even if it isn’t intended to protect night vision (which is worse than red or green).

If you’re looking for something near to the brightness of the sun, look no farther than the color blue. Although it’ll take some time to get used to, it’s better than white.

Night fishing

Blue light is commonly used in many fishing lights on the market. In part, this is due to blue light’s short wavelength, which makes it less likely to disturb fish populations and also allows the fish to float, resulting in visible fluorescence. In addition, several fish species love blue light, which draws them in and makes night fishing easier.

For Industrial Use:

A blue flashlight filter may not be the best choice for checking your garage or basement for oil or chemical leaks, but it is widespread in industrial settings.

Searching for oil, chemical, or coolant leaks on manufacturing equipment is done with a blue light. Leaks can be detected before they become a problem by heavy gear that employs a blue light.

You’d never be able to find that tiny drop of oil if you used a conventional flashlight. Inspecting your equipment on a regular basis will uncover any potential leaks before they become a problem.

Benefits of Using Blue Flashlights

• While blue light is less harmful to night vision than other light colors, it can provide advantages in some situations.

• Detecting blood or delivering medical assistance in dark, isolated areas is much easier with a blue torch light. For this reason, blue light causes blood to glow, making it more easily spotted.

• Maps with red lines, which are invisible in red light, can no longer be read at night without the use of blue light. Practical applications include night walking, military tactical maneuvers, and night flying.

• The only other light that can pass through fog is blue light. Use as a headlight, or in extremely foggy areas, is extremely popular because of this feature.
