Product Name:
SMZ25 Stereomicroscope
The adjustment in the distance of the optical axis allows for maximization of light entry into the optical system at each magnification. The effect is a smooth, wide zoom range, high resolution in both eye paths, and minimal aberrations across the entire zoom range. I use this instrument to check slides for developmental biology experiments and to capture images. It's a little complicated to use but highly recommended due to its high resolution.
