An image processing apparatus that can protect user's eyes by reducing harmful blue light in a mode that matches the characteristics of an image to be displayed and the preference of the user who causes the image to be displayed. The image processing apparatus includes a blue light reduction control unit that acquires image information Sin corresponding to an image to be displayed on a display and a pixel value update unit that generates update image information Sbc by reducing at least luminance corresponding to a blue component in the acquired image information Sin so that a reduction rate of the luminance corresponding to the blue component is greater than or equal to reduction rates of luminance corresponding to the other color components in the acquired image information Sin and outputs the update image information Sbc to the display to cause the display to display the update image information Sbc.

The present invention intends to provide an assay system using split luciferase that has a remarkably high detection sensitivity. In an embodiment, binding of mutually binding first and second proteins is detected by preparing a first fusion protein comprising the first protein fused with a peptide having the amino acid sequence of amino acid SEQ ID NO: 1 and a second fusion protein comprising the second protein fused with a peptide having an amino acid sequence selected from the group consisting of amino acid SEQ ID NOS: 2 to 6, and allowing the first fusion protein to bind with the second fusion protein to form a complex, and detecting luminescence emitted from the complex.

An optical signal emitted from a semiconductor laser is converged by a lens and then received by a single uniaxial birefringent crystal having a C axis that is inclined at an angle other than 90 degrees against a laser optical axis to output an optical signal having a polarized wave component of constant intensity corresponding to the wavelength of the optical signal regardless of temperature changes. The optical signal has an ordinary ray vibrating in a direction perpendicular to a plane including both the C axis and the laser optical axis, and an extraordinary ray vibrating in a direction perpendicular to both the ordinary ray and the laser optical axis. A first main photo detector detects the intensity of a p-polarized component of the optical signal that has passed through a polarizer and a second photo detector directly receives the optical signal converged by the lens.

Wavelength monitoring apparatus

On a plate of birefringent crystal made of an LiNbOcrystal or an LiTaOcrystal, a conductive substance is adhered to the whole periphery of side surfaces of the plate that intersect an incident surface of a laser beam, thereby to form a wave plate. A polarizer is provided at the latter stage of the wave plate. A wavelength is monitored based on an output from the polarizer. With this arrangement, based on the use of the LiNbOcrystal or the LiTaOcrystal that can be manufactured by a large quantity at low cost, it is possible to obtain polarization characteristics and wavelength discrimination characteristics that are stable against environmental changes such as temperature and external stress, by suppressing the pyroelectric effect and the piezoelectric effect of these materials.

Wave length plate, wavelength filter and wavelength monitor

A wavelength monitor comprises a cylindrical lens configured to allow a laser beam emitted from a semiconductor laser to pass therethrough, first and second photodetectors configured to receive the laser beam through the cylindrical lens, and a wavelength filter disposed in an optical path between the semiconductor laser and the first photodetector.

Wavelength monitor and semiconductor laser device

A backward laser beam radiated from a laser diode is received in a photo diode, and an intensity of a forward laser beam radiated from the laser diode is adjusted according to the intensity of the received backward laser beam. The forward laser beam radiated from the laser diode is collimated in a first lens held by a lens holder, and a most portion of the forward laser beam is output through a package window inclined with respect to an optical axis of the laser diode. The remaining portion of the forward laser beam is reflected on the package window as a reflected laser beam and is transmitted through the first lens to be converged in a narrow area placed above the laser diode. A light shielding plate extending in a plane orthogonal to the optical axis is arranged in a wide area including the narrow area and shields the photo diode from the reflected laser beam from. Therefore, the intensity of the forward laser beam radiated from the laser diode is correctly adjusted. Also, the light shielding plate is not soldered to the laser diode but is fixed to lens fixing posts arranged to support the lens holder. Therefore, a driving current can be supplied to the laser diode through a bonding wire without being influenced by the light shielding plate.
