A premium quality range of viewers featuring superb workmanship & attractive finish. High Quality 15-watt daylight fluorescent tubes with a colour temperature of 6500° K provide a bright & even spread of light. Transparent spring loaded film retainers grip lightly & firmly without obscuring top edge details. Rigid welded steel construction finished in white enamel with stainless steel trim. Screen is recessed into the cabinet to help keep the interior dust free and eliminate side light spill. Flicker-free as standard. Available as a single unit. The 2 Way, 3 Way and 4 Way options can be purchased in single or double bank (2 tier) models. Important Design Feature The front opal acrylic screen is not fixed directly to the cabinet and is free to move. This innovative design eliminates screen distortion due to thermal expansion. This means that the film retainers always operate effectively maintaining an even pressure across the full width of the illuminator.
