Coating Science

When selecting optics for hunting in low light conditions, understanding the coating types is crucial for optimal performance. Here are the key principles:

1. Fully Multi-Coated Lenses:
   • These lenses have multiple layers of anti-reflective coating on all air-to-glass surfaces. This ensures maximum light transmission and significantly reduces glare.
   • Example: A fully multi-coated scope will outperform a single-coated one in dim conditions, offering clearer images.
2. Aberration Reduction:
   • Quality coatings can help minimize chromatic aberration, which is the failure of a lens to focus all colors to the same convergence point.
   • Look for coatings that enhance color fidelity and sharpness, ensuring that colors appear true and images are crisp.
3. Color Fidelity:
   • Coatings that enhance color transmission will help in distinguishing between different shades, essential for identifying game in low light.
   • An example is a lens that optimizes green and brown hues, which are predominant in hunting environments.

Transmission Fundamentals

Transmission is the percentage of light that passes through the lenses. For hunting in low-light scenarios:

1. High Light Transmission:
   • Aim for coatings that boost light transmission above 90%. This is particularly important when hunting at dawn or dusk when light levels are low.
2. Impact of Lens Diameter:
   • A 40-50mm objective lens diameter is optimal for low-light performance. It gathers more light, which is essential for clearer images in dim conditions.
3. Coating Types:
   • Anti-Reflective Coatings: These are essential for minimizing light loss due to reflections. Look for fully multi-coated optics, which will provide the best performance by maximizing light entering the scope.

Maintenance Tips

To keep your optics performing at their best, proper maintenance is key:

1. Cleaning Techniques:
   • Use a microfiber cloth to gently wipe the lenses. Avoid paper towels or rough fabrics that can scratch the coating.
   • If necessary, use a lens cleaning solution specifically designed for optical coatings.
2. Avoiding Damage:
   • Store your optics in a protective case when not in use to prevent scratches and dust accumulation.
   • Be cautious in handling and avoid touching the lenses with your fingers, as oils can degrade coatings over time.
3. Regular Inspections:
   • Periodically check for fogging or dirt build-up, especially before hunting trips. A quick inspection can save you from potential visibility issues in the field.

By following these principles and tips, you can ensure that your fully multi-coated optics deliver maximum visibility and performance in low-light hunting scenarios.

The Tool Collective are a multi talented group of passionate hobbyists on a mission to create highly useful and intelligent decision making tools to help others who share our passion and interests. We all have various outdoor hobbies, and hunting specifically, is massive seasonal passion of ours. With hunting comes necessary expansion into firearms and marksmanship. Over the years shooting grew with us to a passion of it's own, instead of being solely a hunting related skill. Long-Range shooting specifically fascinated us and most importantly challenged us. It's incredibly difficult, and incredibly fun and rewarding. It can be daunting to enter the hobby, so we designed these tools to cater to those entering the market for long range optics, and for those looking to advance their skills and setups. Enjoy!
