A beamsplitter is an optical component to serve the purpose of dividing light into two separate beams, often based on their wavelength or polarity. Additionally, these versatile components can function in reverse as beam combiners, merging two light beams into a unified one. The applications of these specialized mirrors are widespread, finding utility in various industries such as laser technology, semiconductor manufacturing, and phototonics instrumentation.

At Avantier, we take pride in manufacturing many types of beamsplitters, for example, a diverse range of top-notch beamsplitters tailored for specific applications, each optimized for superior performance. We offer both plate and cube design options to cater to different customer preferences. Our lineup includes polarizing beamsplitters, non-polarizing beamsplitters, and dichroic beamsplitters, ensuring we meet a wide array of optical requirements. Additionally, our beamsplitters are designed with anti-reflection (AR) coatings to minimize ghosting and maximize efficiency. AR coatings reduce reflections at the surfaces of the beamsplitters, enhancing their overall performance.

Furthermore, we excel in providing custom optical beam splitters, tailoring our products to suit unique project needs. Our beamsplitters are meticulously crafted from high-quality glass, exhibiting exceptional surface quality to allow for precise control over all relevant parameters. At Avantier, our commitment to excellence ensures that our customers receive reliable and high-performing optical solutions for their applications.

Dichroic Beamsplitters:These specialized optical filters polarize electromagnetic radiation through anisotropic absorption. They efficiently transmit light with desired polarization states while absorbing the rest. Dichroic beamsplitters split incident light by wavelength, making them ideal for fluorescence applications and other scenarios where specific wavelength separation is crucial. At Avantier, we take pride in manufacturing top-notch dichroic polarizers with steep edges and flat, high reflection and transmission bands.

Dichroic Polarizer: Avantier specializes in manufacturing high-quality dichroic plate beamsplitters using a unique design and proprietary manufacturing approach. These beamsplitters have steep edges, flat high reflection and transmission bands, and minimize stray light in imaging systems. Avantier offers customization options to meet different wavelength ranges, making their dichroic polarizers adaptable to specific applications.

Polarizing Beamsplitters: These thin film cube Beamsplitters combine the advantageous characteristics of Laser Polarizing Beamsplitters with the added benefit of the broadband application. Within the cube, the polarizing film remains fully protected, ensuring durability and ease of use. Polarizing beamsplitters are designed to handle polarized light, making them essential in various optical systems where polarization control is required.

Non-Polarizing Beamsplitters: Avantier stands as a leading supplier. Our Non-Polarizing Beamsplitters cover a wide range, catering to the Visible (400-700nm), NIR (700-1100nm), and Telecom (1100-1620nm) spectra. The metallic/dielectric hybrid coating employed in these Beamsplitters offers low polarization dependence, resulting in the transmission and reflection for S- and P-polarization states being within a mere 6% difference. Additionally, their spectral flatness across specified wavelengths makes them ideal for use with various laser wavelengths.

Laser Line Polarizing Cube Beamsplitters: Avantier crafts thin film polarizers designed to elevate the performance of your laser systems. These cube beamsplitters are meticulously constructed with a stack of plane surfaces, leveraging the polarization that occurs upon reflection to achieve remarkable results.

Laser Line Polarizing Plate Beamsplitter: Avantier’s laser line plate beamsplitters offer a 50R/50T ratio, polarization insensitivity, durability, premium coatings, and high substrate quality, making them ideal for various laser systems, ensuring precision and reliability with high-caliber substrate materials.

Laser Line Non-Polarizing Plate Beamsplitter: Avantier specializes in customized laser line non-polarizing plate beamsplitters, with a 50R/50T ratio, which are versatile for laser systems, microscopy, and imaging due to insensitivity to beam polarization, various sizes, high damage thresholds, and quality coatings.

Narrowband Beamsplitter Cube: A narrowband beamsplitter cube is an optical device used to split a beam of light into two or more separate beams based on the wavelength or frequency of the light. It is designed to work within a specific, narrow range of wavelengths, typically in the visible or near-infrared spectrum. Beamsplitter cubes are commonly used in various optical instruments and applications, including microscopy, spectroscopy, and laser systems.

Other Types: Lateral Displacement Beamsplitters divide beams into parallel beams with precision, while Laser Beamsplitters separate laser beams into sectors. Beamsplitters are optical components used to split light by wavelength, and their precise control over light manipulation makes them indispensable in various high-tech applications. Laser beam combiners are another critical application, merging beams for enhanced performance in laser systems.
