FAQ

How can IBS-coated VIS anti-reflective optics benefit my Business?

OPTOMAN’s IBS-coated VIS anti-reflective optics, including lenses and windows, stand out for their ability to handle high-power laser applications in the visible spectrum. With low absorption, low surface roughness, and high Laser-Induced Damage Threshold (LIDT), our optics ensure superior performance and longevity. The enhanced lifetime of these optics leads to fewer replacements, consequently lowering your Total Cost of Ownership. 

 

At OPTOMAN, our expert coating engineers ensure that each VIS anti-reflective coating is finely tuned for your specific needs, providing excellent spectral performance and long-lasting solutions for the most demanding laser systems. 

 

At OPTOMAN, our experienced engineers ensure each mirror is finely tuned for your specific application, providing reliable, high-performance laser optics for ultrafast multiwavelength laser systems. 

How can I be sure that these laser optics 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.

Visual anti-reflective optics

Achieving an anti-reflective coating with reflectance below 0.1% at a 45° angle of incidence is relatively straightforward - but doing so for both s- and p-polarizations simultaneously is an entirely different matter. However, after several coatings runs and R&D, this was achieved by OPTOMAN.
