Beamsplitters are essential optical components that precisely split incoming light into reflected and transmitted parts, enabling advanced imaging, sensing, and display technologies. By controlling light paths with minimal loss and high accuracy, beamsplitters enhance system performance across a wide range of applications from overlay metrology to wearable devices.
Materion offers a comprehensive range of beamsplitter solutions designed for exceptional spectral control, durability, and flexibility.
Our portfolio includes:
Polarizing Beamsplitters
Miniaturized for compact wearable devices, these beamsplitters deliver high light throughput with tight tolerances and minimal dead space. Their precise design supports applications such as augmented reality, gesture recognition, and solid-state lighting. Optional patterned or uniform black chrome coatings help eliminate stray light, ensuring clear and vibrant visuals.
Dichroic Beamsplitters
Engineered for sharp separation between reflected and transmitted wavelengths, our dichroic beamsplitters cover the UV to near-infrared (NIR) range with over 90% transmittance and reflectance. Using all-dielectric interference filters deposited by plasma-assisted processes, they offer outstanding environmental stability and customizable filter dimensions and angles. These beamsplitters are ideal for fluorescence detection, Raman spectroscopy, coupling of light sources, and ophthalmologic surgery.
Transflex™ Neutral Beamsplitters
Designed for uniform splitting of light into reflected and transmitted components, Transflex™ beamsplitters provide absorption-free performance across the visible spectrum. Their broadband antireflection coatings and excellent environmental resistance make them highly scratch-proof and reliable for projection equipment, light barriers, and optical sensors. The splitting occurs evenly across the entire surface, allowing installation at various points in the optical path without affecting image quality.
With precise control over spectral characteristics, substrate materials, and coatings, these beamsplitters deliver the perfect balance of performance and reliability.
Whether you’re looking for compact solutions for wearable technology, highly stable filters for scientific research, or neutral beamsplitters for imaging systems. Splitting light exactly where it’s needed and expanding the potential of your optical designs.
