FAQ

How can IBS-coated silicon carbide mirrors benefit my business?

Under extreme environmental conditions, where thermal and mechanical stability are critical to your laser system, OPTOMAN’s IBS-coated silicon carbide (SiC) optics step up to the challenge. Combining SiC’s low thermal expansion, high mechanical resistance, and thermal conductivity with high-performance IBS coatings, these optics are engineered to withstand the most demanding environments without compromising optical performance, ensuring long-term system stability. 


Our SiC mirrors are lightweight and maintain excellent optical performance even under mechanical and thermal stress, making them ideal for applications operating under extreme environmental conditions. The result is consistent beam quality, reduced risk of misalignment, and enhanced system reliability.
 


At OPTOMAN, we design each optic with your application in mind. Whether it’s HR, AR, PR, or polarizing coatings, our experts apply finely tuned-IBS coatings to achieve optimal spectral performance and lasting value. The result is a dependable optic that minimizes downtime, reduces replacement cycles, and ultimately reduces your Total Cost of Ownership.
 

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 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.
