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.
How can I be sure these retroreflectors will fit my application?
OPTOMAN collaborates closely with customers to ensure that each optical component fits the target system’s polarization, power, and wavelength requirements. Whether your priority is precision, robustness, or cost-efficiency, our engineers help optimize optical parameters to match your needs. We assist you in selecting the ideal geometry, whether that is a right-angle retroreflector for simple axis alignment or a hollow corner cube for universal beam return. Our engineering team can calibrate the dihedral error tolerances to meet your precision needs and tailor the IBS coating to optimize performance at your specific operating wavelengths.
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.
