What is F-theta Scan Lens/Field Scan mirror
(1)According to the number of field lenses, there are several types of 0-focus field lenses, such as single lens, double lens, and triple lens. Generally speaking, monolithic field lenses are easier to process, so the price is cheaper. And generally only CO2 field mirrors have monolithic field lenses, why is this, as long as the zinc selenide material of C02 field mirrors is too expensive. Of course, CO2 field mirrors are also available in two-element and three-piece types, but they are expensive because of the large number of materials used and the complexity of processing. According to the wavelength of the field mirror, there are: 266m ultraviolet field mirror, 35m ultraviolet field mirror, 450m blue field mirror, 532m green field mirror, 1064m light red field mirror, 93umCO2 field mirror, 10.2umCO2 field mirror, 106umCO2 field mirror. The most commonly used one is the 1064m light field mirror
