Retroreflectors

Precision optics that return incoming light straight back to its source, regardless of angle of incidence. Built as right-angle assemblies with IBS-coated mirror surfaces and OPTOMAN’s own in-house alignment process, they deliver 10–30 arcsec angular accuracy and near-zero absorption for high LIDT – reliable for laser tracking, surveying and high-power ultrafast systems, and fully customizable on geometry, coating and mounting to fit your application.

Measured performance

Reflectance and GDD are measured in our own metrology lab in Vilnius. LIDT and absorption are measured independently at Lidaris, an accredited laser-damage testing lab. Every graph is labeled as measured or theoretical. Theoretical curves are calculated from the coating design and show the expected performance. You can download the raw data below.

    FAQ

    How can IBS-coated retroreflectors benefit my Business? 

    Integrating IBS-coated retroreflectors into your optical systems provides a significant competitive advantage by enhancing both the long-term reliability and the overall efficiency of your hardware. The Ion Beam Sputtering (IBS) process creates exceptionally dense, high-purity films that are far more resistant to environmental degradation, humidity, and physical wear than traditional evaporative coatings. This durability translates directly into a lower total cost of ownership, as it minimizes the need for frequent recalibration or component replacement. Furthermore, the superior reflectivity and ultra-low scatter of these coatings ensure that your systems maintain maximum signal integrity, allowing your business to deliver high-precision results even in the most demanding industrial environments.

    Can these retroreflectors handle high-power ultrafast laser systems?

    Absolutely. Our retroreflectors are specifically designed to meet the rigorous demands of high-power and ultrafast laser applications. Our IBS coatings provide one of the highest Laser Induced Damage Thresholds (LIDT) available in the industry. Because these coatings have near-zero absorption, they prevent the thermal lensing and surface pitting that often lead to system failure in high-energy setups, making them an ideal solution for advanced research and precision manufacturing.

    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.
