Cruse CS185 Scanner

Our Cruse CS185SL450 Scanner based at HMIF can accommodate an original of up to 1500mm X 1000mm X 100mm high. Its scanning head is rated at 150 Megapixels and it is the only large format ‘heritage’ scanner in New Zealand. Due to its variable-height head we can scan at any resolution between 300ppi and 1100ppi (the smaller the original size the larger resolution we can scan at, up to a maximum size image of 15000 x 10000 pixels). The Cruse scanner uses state-of-the-art computerized focusing rather than ground glass and a focus knob. The elimination of human error guarantees maximum sharpness on all scans.

Pixels on most digital camera backs are 8 microns apart, and most standard lenses will not resolve anywhere that small. As a result, data is not accurately placed on each pixel, consequently lowering the resolution of the scan. Lenses used in Cruse scanners are ultra high resolution and are specially commissioned from Schneider/Kreuznach to address the scanner's unique needs and high resolve down to 5 microns surpassing ordinary copy/photography lenses.

The Cruse scanner uses a patented Synchron™ lighting system, which provides even illumination across the entire surface of the original, while subjecting it to far less light exposure than other methods of illumination. This allows us to use smaller lens apertures for maximum sharpness, while eliminating any glare points or lighting inadequacies.

Our CS185 or "Big Cruse'  scanner is huge, weighing nearly a ton, and we've captured originals up to 30 metres long!
