High Damage Threshold Pentaprisms for Laser Applications


A new range of pentaprisms which offer a unique combination of high laser damage threshold, exceptional environmental stability, excellent mechanical durability and superior optical performance.

REO, a leading manufacturer of high volume precision optical solutions, now offers high performance pentaprisms with coatings optimized for demanding laser applications, such as target designation and rangefinding.  Specifically, these pentaprisms feature all dielectric antireflection and high reflection coatings manufactured using ion beam sputtering (IBS) technology.  IBS delivers fully densified films that exhibit superior laser damage characteristics (over 12 J/cm² in 20 nsec pulses at 1064 nm for the antireflection coatings), as well as exceptional environmental stability and mechanical durability.  This makes them particularly well suited for applications in harsh environments, including exposure to salt spray.  IBS technology also enables highly consistent production of optical coatings with complex spectral characteristics, including multi-spectral operation, where high performance is required at several widely spaced wavelengths or wavelength bands (for example, both 1064 nm and 1573 nm).

REO pentraprisms can be fabricated from a wide variety of materials suitable for the visible and near infrared spectral ranges, including fused silica, optical glasses, Si, Ge, ZnSe and ZnS.  Typical entrance face size range is from 12 mm to 25 mm.  These optics also feature low total wavefront distortion on transmission (<λ/4 at 633 nm), laser grade surface quality (10-5), and high deviation accuracy (≤30 arc seconds). 

REO produces high precision thin film coatings, optics and opto-mechanical assemblies for the ultraviolet, visible and infrared. Located in Boulder, CO, the company primarily services medium to high volume OEMs including manufacturers of defense and aerospace systems, laser systems, semiconductor tools, medical systems, life sciences instrumentation and telecom equipment.  REO is a privately held company.  For more information, contact Mark Damery, Vice President and General Manager of Worldwide Sales, at +1-720-562-3213, e-mail MarkD@reoinc.com, www.reoinc.com, or Susan Anway, Vice President of Finance and Chief Financial Officer at +1-720-562-3206, e-mail SueA@reoinc.com.
