Alternative Title
The flat bed scaner, a helpfull tool for marine organisms cataloguing
Abstract
A cheap and versatile methodology to get digital images of dry and wet preserved organisms, using a flat bed scanner, is presented. To obtain the images of wet specimens, a shallow pool was glued on top of the scanner glass. The pool is filled with water or alcohol and the organisms are immersed and their structures expanded. The best images were obtained with organisms between 1.5 and 15 cm in length. The depth of field was limited to 1.2 cm. These images are also useful for taxonomical research without the need of manipulating the organisms; they can be used too, to compare with better accuracy certain structures between different specimens.
Una metodología barato y versátil para obtener imágenes digitales de los organismos preservados en seco y húmedo, usando un escáner de cama plana, se presenta. Para obtener las imágenes de las muestras húmedas, una piscina de poca profundidad estaba pegada en la parte superior del cristal del escáner. La piscina es llenada con agua o alcohol y los organismos están inmersos y sus estructuras ampliado. Las mejores imágenes se obtuvieron con los organismos de entre 1,5 y 15 cm de longitud. La profundidad de campo se limitó a 1,2 cm. Estas imágenes son también útiles para la investigación taxonómica, sin necesidad de manipular los organismos, se puede utilizar también, para comparar con mayor precisión algunas estructuras entre los especímenes diferentes.
