PURPOSE The Optics and Radiometry Laboratory (ORLAB) provides a testing service for the Australian sunglass industry to assist its compliance with the mandatory Consumer Product Safety Standard. In doing so, a number of sunglasses carrying the CE mark (in effect a claim of compliance with the European Union Personal Protective Equipment Directive) have been tested. Since there is no mandatory t...

The use of short wave infrared (SWIR) imaging and illumination technology is at the forefront of system development for military and law enforcement in both night and daytime operational scenarios 2 3 . Along with enabling nighttime operations, a secondary benefit of SWIR imaging is that it offers the possibility to capture images through tinted materials, such as tinted architectural or automo...

Sunglasses are intended to protect the eye from damage caused by exposure to wavelengths both within the visible spectrum and outside the visible spectrum. Effective sunglass lenses use a combination of darkness and wavelength filtering (color) to reduce brightness and glare and to protect eyes from damaging UVR. Various factors should be considered in assessing the effectiveness of sunglasses,...

3D Modeling is a process of developing 3D objects and their features, having gained popularity during the last decade. As of now, there are many 3D editors to help 3D modeling such as Google’s sketch up, AutoCad, sunglass and others. As these 3D editors have become more useful and 3D-related activities have become rich, collaboration in 3D modeling is getting much attention. In this paper, we p...
