    Abstract: Provided is a lens module with an integrated structure, including a first lens and a second lens, a first substrate and a second substrate, an optical bonding layer, a first absorption layer and a second absorption layer, wherein the first absorption layer includes a copper complex, which is formed from a copper compound, a phosphonic acid represented by formula 1 herein, and at least one phosphorus-containing compound represented by formulas 2 to 4 herein. Due to the integrated structure, the lens module can be reduced in size. The manufacturing process is simplified because no assembly process is required. The lens module of the present disclosure exhibits high transmittance for visible light and low transmittance for near-infrared, showing an excellent near-infrared cut-off effect. In addition, while the incident light irradiates the lens module at different angles, the transmittance curve only is slightly shifted.

    Abstract: An optical isolator for generally collimated laser radiation includes a single polarizing element, at least one Faraday optical element, at least one reciprocal polarization altering optical element disposed at the single polarizing element, at least one reflective optical element for reflecting radiation to provide an even number of passes through the at least one Faraday optical element, and a magnetic structure. The magnetic structure is capable of generating a magnetic field within the at least one Faraday optical element that is generally aligned with the even number of passes along a beam propagation axis. The optical isolator is configured to receive generally collimated laser radiation, which passes through the single polarizing element and the at least one reciprocal polarization altering optical element and which makes at least two passes through the at least one Faraday optical element, whereby generally collimated laser radiation is output from the optical isolator.

    Abstract: An optical isolator for use with high power, collimated laser radiation includes an input polarizing optical element, at least one Faraday optical element, at least two reflective optical elements for reflecting laser radiation to provide an even number of passes through said at least one Faraday optical element, at least one reciprocal polarization altering optical element, an output polarizing optical element, at least one light redirecting element for remotely dissipating isolated or lost laser radiation. The isolator also includes at least one magnetic structure capable of generating a uniform magnetic field within the Faraday optical element which is aligned to the path of the collimated laser radiation and a mechanical structure for holding said optical elements to provide thermal gradients that are aligned to the path of the collimated laser radiation and that provide thermal and mechanical isolation between the magnetic structure and the optical elements.

    Abstract: A film type IRAF filter and the manufacturing method thereof are disclosed. A method for manufacturing a film type IRAF filter includes steps of: providing a first carrier trimmed to a predetermined size in advance; forming a first substrate on the first carrier; forming an intermedia layer on a first surface of the first substrate; forming an Infrared-absorbing filter dye layer on the intermedia layer; forming a first multi-layers optical film on the Infrared-absorbing filter dye layer; forming a release layer on the first multi-layers optical film; removing the first carrier to expose a second surface opposite the first surface of the first substrate; forming a second multi-layers optical films on the second surface of the first substrate; and removing the release layer.
