YOU

At RMI's core is a deep foundation in thin-film coating technology. This enables us to provide advanced solutions from Deep UV to Far IR, and for a wide range of mission critical laser and imaging applications.

​

Full Spectrum Coating Solutions.

VISIBLE

RMI custom coatings in 400-700nm support a wide range of ultra-precision imaging applications including life science microscopy, industrial quality control and satellite
imaging. We offer custom AR designs as well as broadband metal coatings.

 

NIR

As industry pioneers in 1064nm near-infrared laser coatings, RMI offers a full range of custom coating designs from dual/triple-AR coatings to high damage threshold dielectric
and metal mirrors for a full range of Nd:YAG and Fiber laser applications.

MWIR

RMI specializes in non-thoriated, mid-wave infrared imaging coatings from 3-5 µm for defense applications including EO/IR. We are also one of the leading providers of Er:YAG 2.94 µm coatings for medical laser applications.

LWIR

As early developers of infrared coating technology, RMI is equally at home with Far-IR applications like low-absorption CO₂ Lasers in 10.64/10.2/9.3µm wavelengths, as well as long-wave IR thermal imaging coatings from 7-14 µm.
