In this article, we’ll take a closer look at Armortek, LotuTec, and other popular water-repellent coatings used on binoculars.

We’ll explore how they work, their benefits, and why you might want to consider investing in a pair of binoculars with water-repellent coating.

So, if you’re curious about how these coatings can improve your outdoor adventures, keep reading!

What is Water Repellant Coating on Binoculars?

Water-repellent coatings are a type of specialized coating that is applied to the lenses of binoculars to make them resistant to water, moisture, and other liquids.

These coatings work by creating a hydrophobic barrier that repels water droplets, preventing them from sticking to the lens surface and obscuring your view.

There are several types of water-repellent coatings available for binoculars, each with its own unique set of properties and advantages. Here are some examples:

1. Hydrophobic coatings: These coatings are made of a hydrophobic material, such as a silicone-based compound, that repels water and other liquids. They create a smooth surface that prevents water droplets from adhering to the lens surface.
2. Oleophobic coatings: These coatings are made of an oleophobic material, such as a fluoropolymer compound, that repels oil and grease. They are commonly used on binocular lenses to prevent fingerprints and smudges.
3. Multi-coated lenses: Some binoculars have multiple layers of coatings applied to the lenses, including water-repellent coatings. These coatings can help improve image quality by reducing glare and reflections, as well as protecting the lenses from scratches and other damage.
4. Water Repellant Cum Scratch-resistant coatings: These coatings are designed to make the lenses of binoculars more resistant to scratches and other types of damage. They can help prolong the lifespan of your binoculars and keep them in good condition.

Overall, water-repellent coatings are a valuable feature to look for in binoculars, especially if you plan to use them in wet or humid conditions.

They can help keep your lenses clear and free of water droplets, ensuring that you have a clear and unobstructed view of your subject.

How do Binocular Water-Repellant Coatings Work?

Water-repellant coatings for binoculars work by creating a hydrophobic, or water-resistant, surface on the lenses. This surface is typically made of a thin layer of chemical compounds that prevent water from sticking to the lens surface.

When a water droplet comes in contact with a hydrophobic surface, it tends to form a spherical shape and roll off the surface, rather than spreading out and adhering to it. This happens because the hydrophobic surface has a low surface energy, which means it does not provide a favorable surface for the water droplet to adhere to.

Water-repellant coatings for binoculars can be made of a variety of materials, such as silicone, fluoropolymers, or other proprietary chemical compounds. The coatings are applied to the lenses through a process of deposition, where a thin layer of the coating material is deposited onto the lens surface.

Water-repellant coatings can help keep the binocular lenses clear and free of water droplets, especially in wet or humid conditions. This can improve visibility and make it easier to use the binoculars in challenging weather conditions. However, it’s important to note that these coatings are not completely impervious to water and may wear off over time, so it’s important to handle your binoculars with care and follow the manufacturer’s instructions for cleaning and maintenance.

Different Water Repellant Coatings Names By Brands

Some binocular manufacturers have created proprietary water repellant coatings that they use on their lenses. Here are a few examples:

Swaroclean

Swarovski Optik, a well-known manufacturer of high-quality binoculars, spotting scopes, and rifle scopes, offers a specialized water-repellent coating called Swaroclean.

This coating is applied to the external surfaces of the lenses and eyepieces of their binoculars, and it has a hydrophobic and oleophobic effect.

Swaroclean is designed to repel water, oil, and dirt, making it easier to clean and maintain your binoculars.

The coating creates a smooth surface on the lenses that prevents water droplets and other liquids from sticking to the surface. This can be especially useful when using your binoculars in wet or humid conditions, as it can help keep the lenses clear and free of water droplets, fogging, and other obstructions.

In addition to its water-repellent properties, Swaroclean is also scratch-resistant and helps protect the lens surface from damage. The coating is highly durable and can last for years with proper care and maintenance.

AquaDura

AquaDura is a specialized water and dirt-repellent coating that is developed by the renowned German optics manufacturer, Leica.

This coating is applied to the lenses of their binoculars and creates a hydrophobic and oleophobic barrier that repels water, moisture, and other liquids, as well as dirt, dust, and other particles.

The AquaDura coating is applied to the external surfaces of the lenses and eyepieces of the binoculars, creating a smooth surface that prevents water droplets from adhering to the lenses.

When water comes in contact with the lens surface, it tends to bead up and roll off, rather than spreading out and obscuring your view.

This can be especially useful in wet or humid conditions, where moisture can accumulate on the lens surface and impair your vision.

In addition to its water-repellent properties, AquaDura is also highly durable and scratch-resistant. It can help protect the lens surface from damage and prolong the lifespan of your binoculars.

The coating is also easy to clean and maintain, as it prevents dirt, dust, and other particles from adhering to the lens surface.

LotuTec:

LotuTec is a specialized water and dirt repellent coating that is used by the German optics manufacturer, Leica, on their binoculars.

Like AquaDura, LotuTec creates a hydrophobic and oleophobic barrier that repels water, moisture, and other liquids, as well as dirt, dust, and other particles.

The LotuTec coating is applied to the external surfaces of the lenses and eyepieces of the binoculars, creating a smooth surface that prevents water droplets and other liquids from adhering to the lenses. When water comes in contact with the lens surface, it tends to bead up and roll off, rather than spreading out and obscuring your view.

The coating is also easy to clean and maintain, as it prevents dirt, dust, and other particles from adhering to the lens surface.

One key advantage of LotuTec is its ability to maintain its water-repellent properties over time. Unlike some other coatings that can wear off over time or with repeated cleaning, LotuTec is designed to last for the lifetime of the binoculars.

RainGuard:

RainGuard is a specialized water-repellent coating that is developed by Bushnell, an American optics company, for their binoculars.

This coating creates a hydrophobic barrier that repels water, moisture, and other liquids, making it easier to see through the lenses in wet or humid conditions.

The RainGuard coating is applied to the external surfaces of the lenses and eyepieces of the binoculars, creating a smooth surface that prevents water droplets from adhering to the lenses.

When water comes in contact with the lens surface, it tends to bead up and roll off, rather than spreading out and obscuring your view.

The coating is also easy to clean and maintain, as it prevents dirt, dust, and other particles from adhering to the lens surface.

ArmorTek:

This is a scratch-resistant and water-repellent coating used by Vortex on their binoculars. It repels water and other liquids, preventing them from sticking to the lenses and making them easier to clean.

The ArmorTek coating is applied to the external surfaces of the lenses and eyepieces of the binoculars, creating a durable layer that resists scratches and impacts. This layer can help protect the binoculars from damage and extend their lifespan, particularly if you use them in rough outdoor environments.

The water-repellent properties of ArmorTek make it easier to use your binoculars in wet or humid conditions, such as during rainy weather or near bodies of water. The coating causes water droplets to bead up and roll off the lenses, preventing them from obscuring your vision.

Additionally, because the coating repels water and other liquids, it helps keep the lenses clean and reduces the need for frequent cleaning.

In addition to its water-repellent properties, ArmorTek is highly scratch-resistant, helping to protect the lenses from damage caused by rough handling, debris, or other hazards.

This makes it ideal for use in rugged outdoor environments, where your binoculars may be subject to rough treatment.
