1. Features - An observation cylinder with the best comfortable Angle (30°) of the newborn bed can relieve the tension and fatigue of the user during a long working period, ensuring the best observation condition. Observe the scale on the cylinder, convenient for users to adjust the best pupil distance range. - The falling illuminator uses a cora lighting system with FOV apertures, aperture apertures, and oblique lighting devices. Preset offset mirror, offset mirror and color filter slot. - A single 5W LED warm-white lighting (3000-3300K) minimizes visual fatigue for observers, compared with similar LED lighting. - The lathes and apertures adopt a drawbar device with adjustable center, which can flexibly adjust the size of the illumination range and effectively avoid the influence of stray light on the image. 2.
