Hello sir，it's pleasure to receive your glowing review about our white phosphor FOM1600 with autogating image intensifier tube. Our factory commits to providing top - notch service, the speed at which our product was shipped and delivered is something we take great pride in because we understand that waiting for a product can be frustrating, so we've optimized our processes to minimize shipping times. We're especially glad to hear that you consider this tube a great option for beginners. The white phosphor display is carefully engineered to provide a clear and vivid visual experience and autogating is an important new feature that dynamically controls the amount of current that’s fed into the image intensifier. By quickly oscillating - or autogating – current draw by the microchannel plate eliminates the potential for damage due to bright light. BTW, our factory also has grade2 Gen3 green phosphor FOM1600 with autogating IIT in stock，warmest welcome you test it.Once again, thank you.
