| Modular design of Illumination: | No longer limited to a single light source, the modular design of LED and halogen lamps allows for flexible switching based on sample needs. LED light sources generate less heat, eliminate the risk of overheating, and eliminate the need for cooling fans, resulting in an exceptionally long service life and reduced maintenance costs. Halogen lamps, traditionally used as light sources for metallographic microscopes, deliver realistic images and are highly user-friendly. | • | • |
