How to use
Place the Deltaoptical DO-3663 on a stable, level surface and position the specimen on the stage or platform beneath the objective. Turn on the LED illumination and adjust the specimen position until the desired area is within the field of view. Use the focus or distance adjustment provided by the instrument to obtain a sharp stereoscopic image. Observe with both eyepieces for depth perception and, when required, adjust lighting or specimen orientation to improve contrast and visibility.
Usage recommendations
For best results, work in a low-reflection environment and keep the specimen surface clean. Allow the LED illumination to stabilise after powering on before making critical observations. When inspecting electronic components, use antistatic precautions where necessary. Store the microscope in a dust-free location and cover the optics when not in use to maintain image quality.
