FAQ
How can IBS-coated Near-IR laser mirrors benefit my Business?
IBS-coated Near-IR laser mirrors are designed to deliver reliable and consistent performance in laser systems operating in the near-infrared spectrum. These mirrors offer high reflectivity and are optimized for long-term use in demanding environments, ensuring that your laser system maintains peak performance over time. With high Laser-Induced Damage Thersholds (LIDTs), low absorption, and extended operational lifetimes, our mirrors reduce the need for replacements and minimize downtime, making them a cost-effective choice for industrial, medical, and scientific applications that rely on lasers working in the Near-IR part of spectrum.
Moreover, extreme low-loss supermirrors with a maximum reflectivity of R > 99.995% and total losses (absorption, scatter, and transmission) below 1 ppm, which can be used in resonator cavities with extremely high quality factors, are available.
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.
How can I be sure that these mirrors will fit my Business needs?
OPTOMAN digs deep into each application, providing highly customised and application-optimised 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 main price drivers and help customers optimise BOM costs while maintaining the highest quality level.
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.
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.
