Fibre Optics


Puravis GOF120 index fibres


Schott has expanded its portfolio of lead-free Puravis step index fibres for illumination applications to include the GOF120. With its aperture of 0.86, the new glass fibre achieves an aperture angle of up to 120°. This means it is particularly well suited for applications in the field of medical endoscopy, to illuminate internal cavities. The Puravis GOF120 offers high light transmission, yet maintains its natural white light appearance. This enables the technician to make an exact diagnosis when examining tissue samples. Like its two sister fibres GOF70 and GOF85, which were launched two years ago, the GOF120 fibre improves blue light and near-ultraviolet transmission. The glass formula used to


make these fibres includes an improved resistance class, which ensures that Puravis fibres offer even greater long-term stability. As a result, these fibres can be subjected to repeated cleaning and autoclaving without impairing the quality of their light transmission. www.schott.com


Visible wavelength Fiber-Q


Gooch and Housego has introduced a range of visible wavelength versions of its fibre- coupled acousto-optic devices for microscopy and instrumentation applications. The G&H visible


wavelength Fiber-Q is based on the company’s infrared fibre-coupled products and incumbent visible free space solutions. Concentrating primarily on polarisation maintaining products, G&H has demonstrated high polarisation extinction ratio (PER)


and low insertion loss using qualified processes and industry standard TeO2 cells. Depending on the specific wavelength required, optimised PM or SM visible fibre is used. Scientific lasers and


biophotonics applications such


as fluorescence microscopy, confocal microscopy, imaging and spectroscopy are the primary applications for instruments requiring visible Fiber-Qs. Optimised RF drivers for the Fiber-Q are also available. www.goochandhousego.com
