摘要： An optical module which satisfies a required insertion loss and can be easily assembled with high productivity. The optical module includes first optical fiber, a first lens, an optical device, a second lens, and second optical fiber. The first lens receives an incident light from the first optical fiber and converts the incident light into a parallel light. The optical device receives the parallel light and performs predetermined optical processing on the parallel light. The second lens receives a transmitted parallel light from the optical device and converge the transmitted parallel light to produce an outgoing light. The second optical fiber receives the outgoing light. An optical axis of the first lens and an optical axis of the second lens are substantially coincident with each other. An optical axis of the first optical fiber and an optical axis of the second optical fiber are substantially parallel with each other and substantially parallel to the optical axes of the first and the second lenses.

摘要： A method of aligning a fiber collimator in a short time. Light emitted from a collimator is reflected by a mirror. Reflected light passes through the collimator, and is measured by a light intensity measuring device. Rotating bodies rotatably support the mirror about an X-axis and a Y-axis orthogonal to the optical axis. An aligner simultaneously drives the rotating bodies to scan an optimal angle for the mirror. With the mirror fixed at the optimal angle, the distance between a collimation lens of the collimator and the optical fiber is changed. Subsequently, the optimal angle of the mirror is again scanned.

摘要： An optical fiber collimator which facilitates optical adjustment. The optical fiber collimator includes a gradient index rod lens, and an optical fiber optically connected to the rod lens. An anti-reflection film is formed on one end face of the rod lens. The anti-reflection film has a refractive index which continuously changes from a value substantially equal to that of a center refractive index of the rod lens to a value substantially equal to that of the refractive index of the optical fiber along a film thickness direction of the anti-reflection film. A refractive index matching medium having a refractive index substantially equal to that of the optical fiber bonds the anti-reflection film to the end face of the optical fiber.

摘要： A photothermal conversion spectroscopic analysis method which is capable of performing analysis, measurement and detection with high sensitivity. A sample flows in a channel. A exciting light and a detecting light are exited. A gradient refractive index rod lens converges the exited light and forms a focal point at a position in or close to the channel. Intensity of the exited light and passing through the channel are detected. A depth of the channel is not less than two time as large as a difference in distance between focal positions of the exciting light and the detecting light.

摘要： An optical fiber collimator using a gradient index rod lens for securing a required long opposing distance and easy handling. The collimator includes a single mode fiber and a gradient index rod lens for receiving an incident light from the single mode fiber and converting the incident light into a collimated light, or condensing an incident light and coupling the condensed incident light to the single mode fiber. A meandering period (pitch) of a ray determined by a refractive index distribution of the rod lens is decided. The gradient index rod lens has a lens length larger by 0.5 meandering periods than a minimum lens length required to obtain a predetermined opposing distance between a pair of the rod lenses.

The fluorescence measurement probe is applied to a fluorescence measurement system provided with an optical system. A light source emits an excitation light. A detector receives the fluorescent light. A solid light guide path serves as an optical path of the excitation light as well as the fluorescent light. A lens is disposed between an edge surface of the solid light guide path and the specimen. When a radiation angle of the excitation light is set to 2θ at a position where the excitation light is collected by the lens which collects the fluorescent light. A excitation light beam NA expressed by sin θ is set to 0.14 or more and 0.31 or less.
