FAQ

How can IBS-coated Low GDD Near IR mirrors benefit my Business?

IBS-coated ultrafast low GDD Near IR mirrors, designed for wavelengths such as 1030 nm (Yb:YAG), 700-900 nm (Ti:Sa), etc., ensure excellent optical performance (with reflection values up to 99.995%) with broad, minimal and spectrally uniform group delay dispersion (GDD). Moreover, OPTOMAN has developed Superhero Power mirrors that offer a significant competitive edge due to their exceptionally high Laser-Induced Damage Threshold (LIDT), reaching values up to >1.184 J/cm2, 1030 nm, 500fs, 1kHz, reducing the risk of damaging your optics and lowering operational downtime.

Furthermore, the success of these mirrors in your system is ensured by the expertise of OPTOMAN’s skilled coating engineers, who optimize each product for peak performance in its intended application. Their deep understanding of IBS technology guarantees you receive mirrors that thrive in demanding conditions.

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.
