Optical Components News

In high-performance optical systems, managing light—and especially heat—is critical to achieving efficiency, longevity, and accuracy. That’s where Sterling Precision’s cold mirrors stand apart. Designed to reflect visible light while transmitting unwanted infrared radiation, our cold mirrors are engineered to meet the most demanding requirements across medical, industrial, and scientific applications.

🔬 What Is a Cold Mirror?

A cold mirror is a type of dichroic mirror—a multilayer interference-based optical component that reflects visible wavelengths while allowing infrared (IR) light to pass through. The result? An optical system that delivers brilliant, focused light without the thermal load that can damage sensitive components or degrade performance.

At Sterling Precision, we manufacture cold mirrors with exacting tolerances and superior coating technologies to ensure consistent spectral performance across a wide range of angles and applications.

💡 How Our Cold Mirrors Work

Our cold mirrors are constructed using precision dielectric thin-film coatings. These coatings are layered to create constructive and destructive interference at specific wavelengths:

• Reflects: Visible light spectrum (~400–700 nm)
• Transmits: Infrared spectrum (>750–800 nm)

This selective filtration is ideal for systems that need high optical clarity and heat control—allowing visible light to be utilized fully while infrared heat is safely redirected away.

🛠️ Applications Across Industries

Sterling Precision cold mirrors are trusted by engineers and system designers in a variety of sectors:

• Medical & Dental Devices: Eliminate unwanted heat in surgical and examination lighting systems.
• Projection Systems: Ensure bright, crisp images without overheating lenses or filters.
• Scientific Instruments: Maintain stable imaging conditions in microscopes and analytical tools.
• Industrial Illumination: Optimize fiber optic and LED-based lighting with thermal management.
• Laser Optics: Shape and filter laser beams while minimizing heat exposure on optical components.
