Although an advanced microscope is a definite must-have for any lab technician or doctor, one thing is for certain – you need to be able to see what you’re working with in order to assess it properly. This is why illuminators are necessary and extremely helpful. You can purchase a range of models from LW Scientific, including fluorescents, LEDs and fiber optics that range from 10 watts up to 150 watts. Most of these offer shadow-free illumination and screw-on capability.
