对比实施例1
与实施例1的区别在于:将以Si为第二镀膜层材料替换成以Ge作为第二镀膜层镀膜材料,调整后的重新设计膜系结构,发现以Si为基底,SiO为第一镀膜层镀膜材料,以Ge为第二镀膜层镀膜材料无法实现三带通红外滤光片,原因是Ge在1.59um波段具有极高折射率n=5.22,但其并不适用于2.35μm、2.8μm波段。
对比实施例2
与实施例1的区别在于:将以Si为第二镀膜层材料替换成以TiO2作为第二镀膜层镀膜材料,调整后的重新设计膜系结构,发现以Si为基底,SiO为第一镀膜层镀膜材料,以TiO2为第二镀膜层镀膜材料无法实现三带通红外滤光片,TiO2在可见光波段具有极高透射率T=92%,但其只能在并不适用于2.35μm、2.8μm波段。
对比实施例3
与实施例1的区别在于:膜层设计减少最后两层,且将第一镀膜层材料与第二镀膜层材料交换,即以Si作为镀膜材料的第一镀膜层,以SiO为镀膜材料的第二镀膜层;第一镀膜层和第二镀膜层交替镀制。以此得到的膜系结构不成立,无法实现三带通红外滤光片。
对比实施例4
与实施例1的区别在于:将以Si为第二镀膜层材料替换成以ZnS作为第二镀膜层镀膜材料,调整后的重新设计膜系结构,发现以Si为基底,SiO为第一镀膜层镀膜材料,以ZnS为第二镀膜层镀膜材料无法实现三带通红外滤光片,多光谱多晶ZnS是目前用作红外窗口的最佳材料,但是ZnS的理论透射率仅为为75%(不考虑吸收)。
上述具体实施方式仅是本发明的具体个案,并非是对本发明作其它形式的限制,任何熟悉本专业的技术人员可能利用上述揭示的技术内容加以变更或改型为等同变化的等效实施方式。但是凡是未脱离本发明技术原理的前提下,依据本发明的技术实质对以上实施方式所作的任何简单修改、等同变化与改型,皆应落入本发明的专利保护范围。
