Patent number: 9823395Abstract: A multilayer optical film including a stack of microlayers arranged into optical repeat units. At a design angle of incidence, such as normal incidence, the stack provides a 1st order reflection band, a 2nd order reflection band, and optionally a 3rd order reflection band. The 2nd order reflection band substantially overlaps the 1st and/or 3rd order reflection bands to form a single wide reflection band. The wide reflection band may cover at least a portion of visible and infrared wavelengths. The multilayer optical film may include an additional optical layer which maybe be an anti-glare layer and/or may be an absorbing layer. The multilayer optical film is suitable for use as a window film.Type: GrantFiled: October 17, 2014Date of Patent: November 21, 2017Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Michael F. Weber, Edward J. Kivel, Timothy J. Nevitt, Mark B. O'Neill

Patent number: 9678252Abstract: A broadband mirror, polarizer, or other reflector includes at least one stack of microlayers. Microlayers in the stack are arranged into optical repeat units. At a design angle of incidence such as normal incidence, the stack provides a 1st order reflection band, a 2nd order reflection band, and optionally a 3rd order reflection band. The 2nd order reflection band overlaps, or substantially overlaps, the 1st and/or 3rd order reflection bands to form a single wide reflection band. The wide reflection band may include the 2nd and 1st but not a 3rd order reflection band, or the 2nd and 3rd but not the 1st order reflection band, or it may include the 1st, 2nd, and 3rd order reflection bands, as well as still higher order reflection bands. The wide reflection band may cover at least a portion of visible and infrared wavelengths.Type: GrantFiled: February 19, 2016Date of Patent: June 13, 2017Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Edward J.

Patent number: 9562996Abstract: A broadband mirror, polarizer, or other reflector includes separate stacks of microlayers. Microlayers in each stack are arranged into optical repeat units, and the stacks are arranged in series. At a design angle of incidence such as normal incidence, the second stack provides a second 1st order reflection band and a distinct second 2nd order reflection band with a second spectral pass band therebetween. The first stack provides a first 1st order reflection band that fills the second spectral pass band such that a single wide reflection band is formed that includes the first 1st order reflection band, the second 1st order reflection band, and the second 2nd order reflection band. In some cases, the single wide reflection band can include a first 2nd order reflection band of the first stack. In some cases, the first and second stacks may have apodized portions which monotonically deviate from respective baseline portions.Type: GrantFiled: March 15, 2013Date of Patent: February 7, 2017Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Edward J. Kivel, Timothy J. Nevitt, Michael F. Weber
