根据重铬酸铵明胶在受光照后发生交联的原理，采用重铬酸铵明胶作材料制作了微透镜阵列。讨论了制作微透镜阵列的最佳技术条件。提出了已制成的微透镜阵列的一些技术参数。 According to the principle that ammonium dichromate gels are cross-linked after being exposed to light, a micro-lens array is prepared by using ammonium dichromate as a material. The best technical conditions for making microlens arrays are discussed. Some technical parameters of the microlens array have been proposed.
