Partial reflectors (output couplers)
IBS-coated optics that transmit a precise, controlled fraction of light while reflecting the rest, delivering stable performance as intracavity elements or partial-reflection mirrors in external beam paths. Low absorption and predictable reflectance-to-transmittance ratios let you manage intracavity power and fine-tune output energy, while high LIDT keeps performance consistent over a long operational lifetime – customized to your wavelength and split ratio.

FAQ
How can IBS-coated partial reflectors benefit my Business?
IBS-coated output couplers are essential components in laser systems, designed to transmit a controlled portion of the laser beam while reflecting the rest back into the resonator. This balance ensures stable laser operation and consistent output power.
Manufactured using Ion-Beam Sputtering (IBS) technology, our beam splitters offer precise control over spectral performance and extended operational lifetimes, which consequently lowers the total cost of ownership. With high Laser-Induced Damage Threshold (LIDT), these couplers are reliable for high-power laser applications.
Note that a machine is useless if it’s not used properly. The most important component in this equation is the intermediary between the coating design and the IBS machine. That intermediary is the highly skilled and experienced coating engineers that OPTOMAN is proud of.
Is it possible to test the optics and how scalable is the production?
Yes. Based on the customer’s presented business case, OPTOMAN, with its R&D-driven attitude and collaborative approach, can design, develop, and manufacture products for testing purposes and present a plan for serial production. Different-size IBS coating chambers are very handy in this case because small-scale production can be easily transferred to our giant IBS machine – Albert (the atom smasher), where we can coat large optics or 400-500 units of 1“ laser optics in a single coating run, ensuring high uniformity, meaning that all mirrors will work the same making your laser systems highly repeatable and reliable too.
Moreover, our in-stock optics marketplace, OPTOSHOP, features over 400 different laser optics made with love by OPTOMAN. These optics can be provided for testing directly from stock and delivered in 1-3 business days. After successful tests, OPTOMAN can present the most optimal production plan matching your business needs.
How can I be sure that these laser optics will fit my Business needs?
OPTOMAN digs deep into each application, providing highly customized and application-optimized solutions that will fit your business needs.
Together, we will be able to set the priorities that are most important for your application and needs, whether it is reaching fundamental limitations, proving the concept, or making a well-balanced industrial high runner. We keep an open discussion about the main price drivers and help customers optimize BOM costs while maintaining the highest quality level.
Does OPTOMAN provide optics or only coating service?
Both. 80% of total OPTOMAN revenue comes from complete products, while 20% is generated by providing coating services on customer-supplied substrates. OPTOMAN responsibly oversees the supplier network for reliable substrates and, if needed, can offer a completely European supply chain.
Does OPTOMAN have available substrates ready to coat?
Yes. OPTOMAN has a number of flat substrates, plano-concave and plano-convex lenses, and spherical mirror substrates in stock, ready to be coated. Choosing the in-stock substrate option allows, on average, saving 6 weeks of lead time and reducing end-product cost 3 times.
