An object of the present invention is to provide a half-mirror film for displaying a projection image having high adhesiveness, a laminated glass in which wrinkle generation of the half-mirror film is suppressed or furthermore has high adhesiveness, and an image display system using the laminated glass. The problem is solved by providing a half-mirror film for displaying a projection image including a transparent support; and a selective reflection layer reflecting light in a wavelength selective manner, in which the transparent support has an absolute value of 10 nm or less of an in-plane phase difference at a wavelength of 550 nm and a heat seal layer disposed on an opposite surface of a surface having the selective reflection layer, the heat seal layer contains a thermoplastic resin, and a mixed layer in which components of the transparent support and the heat seal layer are mixed is formed between the transparent support and the heat seal layer.

An extended optical pulse stretcher is provided that combines confocal pulse stretchers in combination to produce, for example, 4 reflections, 4 reflections, 12 reflections, and 12 reflections per optical circuit configuration. The inclusion of the combination of different mirror separations and delay path lengths can result in very long pulse stretching, long optical delays, and minimal efficiency losses. Also, in the extended optical pulse stretcher, at least a beam splitter can be positioned relative to the center of curvature of the mirrors to “flatten” each of the circuits to enable the beam to propagate in the same plane (e.g., parallel to the floor). Also, the curvatures and sizes of the individual mirrors can be designed to position the beam splitter closer to one of the banks of mirrors to allow the optical pulse stretchers to properly fit in an allocated location in a laser system.

Methods and systems are provided for an auto-focus system for a microscope. In one example, a method for the auto-focus system includes focusing the microscope at a glass-specimen interface of a sample by passing a primary laser beam through a beamsplitting device to generate an additional, secondary laser beam that is a mirror image of the primary laser beam. A location of an objective may be triangulated along a longitudinal axis of the microscope based on a centroid of spectral intensities of each of the primary and secondary laser beams.

A light source module including first and second light sources, first and second wavelength conversion units, first and second light-splitting units is provided. The first light source emits a first light having a first wavelength. The first wavelength conversion unit converts at least one portion of the first light into a first converted light having a second wavelength. The second light-splitting unit allows the light having the first wavelength to travel through and reflects the light having the second wavelength. The second light source emits a second light having the first wavelength. The second wavelength conversion unit converts at least one portion of the second light into a second converted light having the second wavelength. The first light-splitting unit disposed between the first and the second wavelength conversion units reflects the light having the first wavelength and allow the light having the second wavelength to travel through.
