Laser users love novel flip filter design that modifies eye protection

NoIR LaserShields are now shipping the CE-certified Frame 40 spectacle. With its novel flip mechanism, which allows for a secondary filter to be brought into play in certain applications, users can benefit in situations where a modification of the passband of the fixed filter is required.

In this example, the fixed filter is FG1 glass for IR sources above 900 nm, and the secondary filter is the AXX which blocks UV and IR in between 700 and 900 nm.

OZ Optics introduces new Variable Bandwidth Tunable Filter

OZ Optics has introduced a new tunable filter that has the ability to tune both the centre wavelength and the transmission bandwidth.

Two independently adjustable thin-film filters allow the setting of the lower and upper edges of the pass-band region. With this method, the pass-band can be tuned from 1 to 18 nm FWHM and the centre wavelength shifted by over 40 nm.

BTF

The transmission band features a flat-top profile, providing uniformly low losses and low PDL across the pass-band region, and high rejection ratios outside the pass-band. Devices can be custom made for wavelength regions of interest and can use either singlemode or polarisation maintaining fibres.

Two manual controllers to set the upper and lower pass-band regions, with an electrically controlled model due later this year. Applications include WDM testing, spectral filtering, spectral imaging or microscopy, and others.

For more information, please contact us.


More eye protection from lasers: NoIR LaserShields expands range in UK

With the news of multiple high-profile incidents involving laser pens being pointed at passenger aircraft; Elliot Scientific welcomes the recent addition of four more CE-certified laser filters and several new stylish frames to our existing NoIR LaserShields® range. The filters are:female-31

AG4 – blocks UV and 532 nm green light sources

YG5 – blocks IR lasers operating around 1064 nm

RT1 & RT2  – attenuate UV, 532 nm green and near-IR from about 800 to 1064 nm, making them ideal for visual alignment applications or laser pointer protection

Eyes can be permanently damaged by direct or reflected exposure to lasers, high-power LEDs and plasmas – arc welding for example.

NoIR safety eyewear is designed to absorb specific light energies, and must be selected by considering source wavelength(s) and peak irradiance, required optical density (OD), visual light transmittance, field of view, effects on natural colour rendition and frame comfort.

A number of frame styles are now also available in white, while an extra small model has been introduced for petite faces, adolescents and pre-teens. This will allow paediatric, medical and dental services involving laser treatments to offer better eye protection for children.

Your eyesight is important! Please contact us if you work with, or might be affected by, lasers or any other intense light source.

Retinal injury occurs from exposure to visible, such as the possible Blue Light Hazard effect, or near IR energy (400-1400 nm), while corneal or lens damage results from UV (190-400 nm) and IR (1400-11000 nm) exposure.

 

 


New additions to laser safety filters from NoIR LaserShields

female-31NoIR LaserShields has had ten of their existing filters for laser safety CE-approved. These are the: 10, 50, 60, 90, 92, 5032, 6032, RT1, RT2 and YG4.

NoIR also revealed, at the recent Laser World of Photonics exhibition, a breakthrough polymer filter for Holmium-doped fibre lasers operating between 2 and 3 microns – the HOY.

NoIR have been manufacturing high-quality internationally-certified safety eyewear for the protection of laser users in a broad range of fields and applications for many years now, offering protection from:

  • UV, visible, and IR lasers
  • Multiple waveband devices
  • Therapeutic and cosmetic treatments (Patients and Clinicians)
  • Laser pens (Pilots and Police)

Elliot Scientific’s expert advice will guide you to the best in cost-effective laser safety. From academics, beauticians and clinicians… we protect the alphabet of laser users. Contact us with details of your laser or application and we will be happy to help you choose the correct filters, spectacle frames or goggles.

NoIR LaserShields® introduced by Elliot Scientific

Elliot Scientific’s existing laser safety portfolio is now complemented by our introduction of the NoIR LaserShields® eyewear product range.

NoIR LaserShields®, who have been manufacturing laser safety eyewear for multiple applications since 1996 following its creation by parent company NoIR Medical Technologies, offer a comprehensive group of filters for protection against specific or combined laser wavelengths, a broad choice of frames to suit your face and pocket, and additional products for patient/client protection and pilots.

More details on the NoIR LaserShields® Elliot Scientific offers can be found within the comprehensive product pages that show the filter groups, frame styles, and extras, along with datasheets and CE Certificates.

If you have a requirement for laser eye protection, do contact us for advice on choosing the right eyewear as we always recommend you consult your laser safety officer, appropriate laser safety standards, and/or laser system documentation to ensure correct choice of eyewear and safe laser use.

Remember, laser safety eyewear only offers protection against incidental exposure to specified beam energies so incorrect choice and use may lead to serious personal injury or blindness.
