FLIR / Thermal Imaging Optics
To keep up with the rapidly evolving capabilities of next-generation IR sensors and detectors, optical component manufacturers must stay on the leading edge of manufacturing technologies to support the increasing technical requirements of the FLIR community. RMI brings over 30 years of continuous advancements in IR production capabilities delivering on difficult custom solutions including diamond turned IR aspheric lenses, large IR elements (up to 12” dia), environmentally durable MWIR & LWIR coatings as well as IR opto-mechanical assemblies, offering a full-service, one stop shop for IR imaging system OEMs.
Diamond Turning Capabilities
RMI understands that critical design considerations for high performance FLIR optical systems include savings in weight, space and cost. Infrared optical elements featuring aspheric lens surfaces boost the imaging performance and efficiency of optical system designs by allowing for the combination, and thereby reduction, of the number of optical elements while still obtaining full coverage of the detector. RMI’s precision, 3-Axis Diamond-Point Turning (X,Y,C) produces flawless custom aspheric lens surfaces on a wide range of IR substrates to allow designers to reach their performance goals.
