Product catalog summary

Introduction
Almeco's lighting application products focus on highly reflective aluminum materials, achieving up to 98% total reflectance. This is a result of advanced technical developments combining bright anodizing processes with vacuum surface coating technology.

Product Structure
The products are based on high-purity aluminum substrates, starting with an anodized base coat for durability. They are then vacuum-coated with a reflection layer of either 99.99% pure aluminum or silver, overlaid with a dual-layer oxide system to enhance reflectivity and protection.

The Bernburg PVD Line
Located in Bernburg, Germany, this facility is equipped with state-of-the-art systems for roll-to-roll metal surface treatment using PVD processes, enhancing product quality and efficiency.

Product Advantages
Almeco's products improve optical performance and luminous efficiency by 10-20%. The high reflectivity ensures minimal light loss, even with multiple reflections, making them ideal for various lighting applications.

Product Range
The range includes various reflector surfaces and textures, with key finishes designed for high efficiency and aesthetic performance. Products are available in formats suitable for the lighting industry.

Key Characteristics
Products offer high total reflectance across wavelengths from 400 to 700 nm, ensuring excellent color rendition and minimal light loss. Coatings are applied using advanced deposition technologies for optimal adhesion.

Applications
Almeco's products are suitable for a wide range of applications, including:

Lighting: High-efficiency luminaires and T5 fluorescent luminaires.
Daylighting: Reflective surfaces for light pipe construction.
