Led Flashlights Mysteries: Polycarbonate, The Titanium Of Flashlight Lenses
Polycarbonates are known as parts of thermoplastic polymers. These plastics are widely used in chemical industry. There are some of the important features such as they have temperature resistance and posses optical properties. They can also be used in manufacturing of baby bottles and water bottles. These plastics can also be used in lightening lenses to improve the quality of light because of their optical properties. Polycarbonate plastics are used for making lenses because of their durability, transparency and high infraction index. Polycarbonate lenses are thinner than the glass lenses or other conventional lenses and are almost unbreakable.
Polycarbonate in Flashlight Lens
As polycarbonate lenses are unbreakable, they reduce the risk of getting damage and they are light-weighted. This is the reason why they are more expensive than glass and other lenses. The polycarbonate lenses are able to correct poor quality of light and hence are used in flashlights so that the quality of light can be improved. They also have scratch resistance coating, which prevents any distortion in light omitted by LED flashlight and hence give out high beam of light. They can easily be molded and shaped as per the requirements and can be fitted well in the flashlight medium.
Advantages of polycarbonate lenses over glass lenses
There are various advantages of using polycarbonate lenses over glass lenses. Some of them are listed below:
- Polycarbonate lens are ten times more impact resistant than any other plastic lenses and glass lenses.
- Glass lenses can be broken when hit even with slighter force. Polycarbonate lenses are almost unbreakable so the damages are comparatively lesser.
- Polycarbonate lenses have 100 percent UV protection from the sun's harmful rays.
- The lenses made up of polycarbonate plastics are more durable and are scratch resistant.
- These lenses are lighter than the glass lenses.
However, there are some significant disadvantages associated with polycarbonate lenses. This is known as oxidation or discoloration. It is impossible to figure out with naked eyes but these polycarbonate lenses are made up of the materials which expand when exposed to heat or higher temperatures. This can cause debris, dust and UV rays to enter the lenses over a period of time. The oxidation can also lead to fading and the lens can appear foggy and cloudy over a period of time. Due to the deterioration of the lens the quality of light can also be affected and you may not get the same quality which you received in the initial days.
Depending upon the retirements, you can select the best product for you. However, the disadvantages do occur with the passage of time. You can still go and get flashlights which have polycarbonate lenses in order to experience the benefits.
It will always be a wise decision to get the LED flashlight so that you can enjoy the high beam of light with better quality. These products are used by people all over the world. You can choose the right product by shopping around and reviewing these products.
