Pentaprisms from REO use ion-beam-sputtering technology

High-performance pentaprisms are available with all dielectric antireflection and high reflection coatings manufactured using ion-beam-sputtering technology. The optics can be fabricated from a variety of materials, including fused silica, optical glasses, Si, Ge, ZnSe, and ZnS, with wavefront distortion <λ/4 at 633 nm, surface quality 10^-5, and deviation accuracy ≤30 arcsec.

PRESS RELEASE

REO Introduces High Damage Threshold Pentaprisms for Laser Applications

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).
