LUVIS mini light box for small vision charts


The LUVIS mini is a new light box for small format vision panels. It can be ideally used with the MARS contrast panels. Simply stick four magnetic adhesive strips on the back of the board, insert the panel into the LUVIS mini, and switch it on to check contrast vision without illumination errors! Fits charts of up to 38 x 28cm. Comes with power cord (100 - 220 V).

Modern illumination design


In the design, the research team followed the specifications of DIN EN ISO 8596 it describes the conditions under which visual acuity and contrast vision tests must be performed. Important: Homogeneous lighting as required by EN ISO 8596 cannot be achieved with conventional room lighting! The two LED strips illuminate the box homogeneously. This allows the light to fall on the panel in such a way that no reflections occur. In addition, the housing provides protection from incident light. Anyone who has ever tried to illuminate a contrast panel with conventional lighting knows these difficulties. The result then depends on factors for which one is responsible as a professional. With LUVIS mini you are rid of these risks once and for all!

The importance of ISO 8596


EN ISO 8596 specifies an ambient brightness (luminance between optotypes) of between 80 and 320 cd/m2 for visual acuity testing at high contrast to the visual signs. This range is also recommended for testing photopic contrast vision. The permissible tolerance is specified as ±25 %.
With LUVIS mini, you achieve a tolerance of only ±3 % over the entire chart! This means that a letter at the top left will appear a maximum of 6% lighter or darker than a letter at the bottom right.
