Searching for dependable optical beamsplitters with unmatched precision? At i-Photonics, we specialize in manufacturing sophisticated laser beamsplitter optical coatings meant for use in telecommunications, medical devices, and scientific instruments. Using cutting-edge thin film deposition processes and meticulous quality assurance, we employ bespoke solutions that meet your standards, build to last and perform optimally.

What is a beamsplitter coating?

It is an optical thin-film applied on a beam splitter that reflects or transmits beams of light at certain geometric ratios preferentially. Those thin films beamsplitter coatings are fundamental in applications that require the use of light as a controllable tool, such as for:

Laser systems (steering, beam splitting, and interferometry);
Telecommunications (signal routing and filtering);
Medical devices (imaging, diagnostic);
Scientific instruments (spectrum and micro-analyzing).

No matter if you require control over polarization, splitting angles, or wavelength separation, our films provide high efficiency.

Types of beam splitter coatings

To accommodate the different ranges of optics used in the world, we offer several beamsplitter coatings, such as:

Single Wavelength Beamsplitters — Specifically tailored for exact lased lines (e.g., 532 nm, 1064 nm) laser lines having a splitting ratio (50/50, 70/30, etc.);
Broadband Beamsplitters — Those beam splitters show consistent performance in the wide spectral regions extending from the UV region to the middle infrared;
Polarizing beamsplitters — Split light according to their polarization, most suited in Laser and imaging systems.

Our minimum absorption durability and high resistance to environmental conditions make this design stand out from others.

Deposition technologies used

Our beamsplitter coatings are produced using state-of-the-art deposition methods:

Ion beam sputtering (IBS) — Delivers ultra-dense, low-scatter coatings with <0.6% thickness variation;
Plasma-assisted Reactive Magnetron Sputtering (PARMS) — Achieves exceptional uniformity (up to 0.01%) for large optics;
Plasma-assisted Ion Deposition (PAID) — Ensures high adhesion and environmental resistance.

Every coating undergoes strict quality checks to meet industry standards.
