摘要： An optical path folding element (100) includes an optical portion (110), a connection portion (120), matte structures (130) and a light blocking layer (140). The optical portion (110) has an optical surface (111) and two reflective surfaces (112, 113). A light beam enters into the optical path folding element (100) via the optical surface (111) and is reflected inside the optical path folding element (100) through the optical surface (111). Each reflective surface (112, 113) is configured to reflect the light beam again inside the optical path folding element (100). The connection portion (120) has connection surfaces (121) connected to the optical surface (111) and the reflective surfaces (112, 113). The matte structures (130) are at least disposed on and integrally formed with the connection portion (120). Each unitary structure of the matte structures (130) is tapered off and recessed from the connection portion (120), such that the outer surface of the connection portion (120) has an undulating shape. The light blocking layer (140) is at least disposed on the connection portion (120) for blocking light.

The main body (39, 39a, 39b, 39c, 39d, 39e, 39f) has an optical surface (310) including an incident surface (311), a reflective surface (312, 312d) and an emitting surface (313). A light enters into the optical path folding element (30, 30a, 30b, 30c, 30d, 30e, 30f) through the incident surface (311). The reflective surface (312, 312d) reflects the light so as to change a traveling direction thereof. The light exits the optical path folding element (30, 30a, 30b, 30c, 30d, 30e, 30f) through the emitting surface (313). The light absorption film layer (320) is configured to reduce reflectance and provided adjacent to at least part of the optical surface (310), and the light absorption film layer (320) is in physical contact with the main body (39, 39a, 39b, 39c, 39d, 39e, 39f). The matte structure (330) is disposed adjacent to at least part of the optical surface (310). The matte structure (330) provides an undulating profile on a surface of the optical path folding element (30, 30a, 30b, 30c, 30d, 30e, 30f), and the matte structure (330) is formed in one-piece with the main body (39, 39a, 39b, 39c, 39d, 39e, 39f).

摘要： An IR cut filter for inhibiting occurrences of flare and ghost is provided. A solid-state imaging device comprises a CMOS sensor, a circuit board, a ceramic plate, an IR cut filter, a taking lens, a lens holder, and a support barrel. The CMOS sensor is mounted on the circuit board. The circuit board is fixed to the ceramic plate such that the CMOS sensor is placed inside an opening of the ceramic plate. The sides of the CMOS sensor are surrounded by the ceramic plate. The IR cut filter is fixed to the ceramic plate so as to cover the opening. The CMOS sensor is disposed behind the taking lens. The IR cut filter is disposed between the taking lens and the CMOS sensor. A light-shielding layer is formed over the entire periphery of edge portions of an incident surface of the IR cut filter. Harmful rays such as reflective light is blocked by the light-shielding layer.

摘要： A device for detecting electromagnetic radiation comprises a waveguide and at least one resonator on a substrate, and a low-refractive index region between each resonator and the substrate. The low-refractive index region has a lower refractive index than a material of the resonator. The low-refractive index region may be annular, and may have a width corresponding to a width of a region in which electromagnetic radiation is concentrated in a whispering-gallery resonant mode. The low-refractive index region may be an air gap between the substrate and the resonator. The device may be a spectrometer for detecting a plurality of predetermined wavelengths of electromagnetic radiation.

摘要： An optical assembly and a method for making the optical assembly. The optical assembly includes an optical element; a blocking coating; a capping layer on the blocking coating; a holder; and an adhesive configured to adhere the optical element to the holder. The blocking coating includes a light absorber that does not transmit light with wavelengths from greater than or equal to about 250 nm to less than or equal to about 400 nm; The light absorber is positioned such that light having a wavelength from greater than or equal to about 190 nm to less than or equal to about 500 nm is not incident to the adhesive. The capping layer is made from a material having high transmission in the UV and enables use of aggressive cleaning treatments on the optical element significant impairment of the UV transmission of the optical element.
