High-Res, High Zoom Ratio
The SZX16 is a research instrument with a maximum numerical aperture of 0.3, which can produce a resolution of 900 line pairs/mm. It has full fluorescence capability, which enables researchers to extract the maximum information from experiments. “Fluorescence imaging is such an important technology, especially now that there are many new dyes on the market for the functional analysis of living species,“ says Dr. Busch.
“There is also a trend toward using this technology to understand the complete organism, rather than just one cell, which means stereo microscopes are being used even more.“
At 16.4:1, the SZX16 has the highest zoom ratio of any stereo microscope currently on the market, according to the company. This allows the user to go from whole organism to the cellular level and back with no major adjustments. It also has enhanced 3-D vision, which makes it good for micromanipulations of cells, such as microinjection.
Meanwhile, the SZX10 is for advanced routine applications, such as quality control and specimen identification. “The instrument is applicable where a natural view is needed, where morphological comparison might be wanted,“ explains Dr. Busch. A further feature of the SZX2 series is its use of light-emitting diodes as a cold light source, thus not heating up the specimen.
The SZX16 can also be used with the new infrared dyes that minimize the bleaching of the specimen. The SZX2 also carries a correction ring, which can compensate for the optical aberrations caused by the different refractive indices of air, petri dish cover, and water.
