Illumination for every type of specimen Easily overlooked, as all photographers know, is the illumination of specimens which has a profound effect on the quality of the images captured. It is even more important when stitching adjacent images together because variation in illumination can create sharp boundaries between images which can spoil the appearance of the stitched image overall.
A program of careful testing of a diverse range of illumination techniques has resulted in a set of specially developed solutions designed for each size of scanner and subject type.
With high intensity light sources the lens and camera apertures can be kept partially closed resulting in extended depth of focus without compromising optical clarity.
Diffuse light sources are used to minimise reflections, high frequency lamps eliminate camera interference and cool light sources reduce subject damage.
Quality images from quality optics A crucial part of any imaging system is the optical assembly. We have designed a set of optics that are distortion-free, telecentric and fully motorized.
High performance camera The resolution of the digital camera in a system like this is not as important as its remote controllability, speed of data delivery, quality of the image and color correctness. We are using a family of cameras perfectly matched for this task, this family includes a 3CCD model with perfect color reproduction. For increased scan resolution it is better to magnify the subject further using the zoom on the lens and capture more images.
