The utility model adopts the following technical scheme: the utility model relates to a straw hat type quartz lens, including the preform, the preform is quartz lens, the preform bottom sets up for evagination arc structure, the preform top is the plane setting, be equipped with fixed limit on the circumferencial direction at preform top edge, fixed limit top and preform top are in same horizontal plane.
Further, the top of the fixed edge and the top of the prefabricated body are arranged in a smooth plane.
Furthermore, the fixed edge is a high-transparency aromatic heterocyclic polymer resin fixed edge, and the fixed edge can transmit the deep ultraviolet of 180-300 nm.
A production process of a straw hat type quartz lens comprises the following steps:
firstly, obtaining a required quartz lens surface through cold processing to obtain a prefabricated body;
secondly, placing the prefabricated body in a mold, filling the prepared powder into a gap between the edge of the prefabricated body and the mold, then placing the mold in a sintering furnace for heating, liquefying the powder to fill the gap between the mold and the prefabricated body after the temperature reaches the melting point of the powder, cooling and solidifying the powder to form a fixed edge after slow cooling, and integrating the fixed edge and the prefabricated body into a whole to obtain a semi-finished product;
and step three, taking the semi-finished product out of the die, and then removing redundant powder in a grinding and polishing mode to obtain a finished product with a smooth surface.
Furthermore, the melting point temperature of the powder is far lower than the softening point temperature of quartz.
Further, the heating temperature in the sintering furnace is higher than the melting point temperature of the powder and lower than the softening point temperature of the quartz.
Further, the die is a high-temperature-resistant metal die.
