The SMZ445 and SMZ460 are a pair of compact, Porro-prism based zoom stereo microscopes designed for versatile laboratory observation. The SMZ445 offers a 0.8x to 3.5x zoom range, while the SMZ460 provides 0.7x to 3.0x, both delivering high-quality images with superior flatness. A key feature is the long 100mm working distance, facilitating safe manipulation of specimens with tools. They come with an all-in-one C-LEDS Hybrid LED Stand providing both diascopic (transmitted) and episcopic (reflected) illumination, which can be individually adjusted. The zoom body features a mold-resistant finish for durability in humid environments, making them ideal for educational, research, and routine inspection of diverse specimens.
