A Dog's Life - "real lab bench experience" |
Microscopes have evolved over the past five years. Have your experiments kept pace? With the cost and reliability of solid state imaging and illumination components improving in recent years, it's no wonder that these are being adopted by many microscope producers to create better and cheaper systems. The LED technology has created a great alternative to mercury arc lamps and lasers. Less expensive and far more reliable than either, the only drawback is the intensity and range of wavelengths. These are quickly being resolved by newer, brighter chips in an ever increasing variety of colors. On the detection side, CCD have been the gold standard for electronic imaging components. In recent years, CMOS detectors have become a darling of systems engineers as the inherent low noise and low cost make it a smart choice for many applications. Both technologies have merits, and the choice for the microscope is really dependent upon intended applications. Many microscopes have dispensed with eyepieces and have instead introduced external monitors for visualizing images. Often these displays are integrated into the microscope, but in some instances can be located remotely for situational imaging opportunities, such as in a cell culture incubator.
