HRsp>99.9% @ 515 nm + HRsp>99.3% @ 500-530 nm + Rsp<2% @ 1030 nm, AOI=45° (DM77)
Dichroic mirrors
IBS-coated dielectric filters that transmit one wavelength band while reflecting the rest, with minimal absorption and sharp, spectrally stable edges – no drift over time, even under high power. High extinction ratios between transmitted and reflected beams, plus minimal pulse dispersion, make them reliable for pump light injection, intracavity frequency doubling, harmonic separation and fluorescence microscopy alike, whether you’re building a laser resonator or a complex imaging path.

FAQ
How can IBS-coated dichroic mirrors benefit my Business?
IBS-coated dichroic mirrors give precise wavelength control, reflecting some wavelengths and transmitting others with high efficiency. Harmonic separators split fundamental and harmonic wavelengths. Pump mirrors handle the reflection and transmission of pump and output wavelengths for efficient energy transfer. Long pass and short pass filters transmit longer or shorter wavelengths while blocking the rest. All of them have a steep, repeatable transition between reflection and transmission, which gives high performance and efficient beam combining across the spectral range from 193 nm to 5000 nm.
Ion-Beam Sputtering (IBS) gives these coatings high Laser-Induced Damage Thresholds (LIDT), so they perform reliably under high-power laser conditions. For ultrafast UV applications, OPTOMAN has developed a technology for HR + HT coatings at 257–343 nm with fs laser pulses that lets harmonic separators withstand over 10000 hours of laser irradiation. Extended operational lifetimes mean fewer replacements, less downtime and lower maintenance costs, which lowers the Total Cost of Ownership (TCO). This matters most in industrial and scientific applications where long-term reliability is key.
At OPTOMAN, our expert coating engineers fine-tune each dichroic mirror for your specific needs, giving you excellent spectral performance and long-lasting solutions for the most demanding laser systems.
How can I be sure that these mirrors 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 optimize 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.
