Inspect various microscopic samples wherever you are with this rugged, easy-to-use handheld microscope. Use the convenient windowed positioning adapter to place the microscope over your sample, and simply rotate the eyepiece to adjust the focus. With their small size and sturdy design, TRM-C microscopes are ideal for years of trouble-free field use. TRM-C microscopes feature coaxial illumination provided by a bright white LED. Coaxial light travels along the same axis as the sample, reflecting at a 90° angle to produce a clear, crisp, and highly detailed image. Several magnifications are available, ranging from 100x to 400x, with a field of view from 1.6mm to 0.465mm.
