Abstract: A spectrometer is disclosed. The spectrometer includes a fiber input, a collimator lens, a rotating shaft, a grating, a focal lens and a focal plane which have arranged in order. A broadband incident light of the fiber input becomes a first parallel beam through the collimator lens and separated by the grating into multiple parallel beams of different wavelengths and then focused by the focal lens to emit an output beams to an imaging position on the focal plane. The spectrometer can rotate the collimator lens and fiber input to change the imaging position on the focal plane.

Abstract: An optical detection system integrating tonometer and autorefractor includes first and second optical modules. The first optical module includes a light source, first and second lens sets, a reflector, a first light-splitter and a sensor. The first lens set and reflector are disposed corresponding to light source. The first light-splitter is disposed corresponding to the reflector, second lens set and sensor. The second optical module includes a second light-splitter and first to third optical elements. The incident light emitted by the light source passes through the first lens, reflected by the reflector, passes through the first light-splitter, reflected by the second light-splitter, passes through the first to third optical elements and emitted to an eye. A sensing light from the eye passes through the third to first optical elements, reflected by the second light-splitter and first light-splitter, passes through the second lens set and emitted to the sensor.

Abstract: An optical system applied to an optical biometer is disclosed. The optical system includes a light source, first and second switchable reflectors, and first and second fixed reflectors. The first switchable reflector is disposed corresponding to the light source. The second switchable reflector is disposed corresponding to an eye. In a first mode, the first and second switchable reflectors are switched to a first state, and the incident light emitted by the light source is reflected by the first fixed reflector along a first optical path and then emitted to a first position of the eye. In a second mode, the first and second switchable reflectors are switched to a second state, and the incident light is sequentially reflected by the first switchable reflector, the second fixed reflector and the second switchable reflector along a second optical path and then emitted to a second position of the eye.

Abstract: An optical biometer including a light source, a first-stage coupler, a first and a second second-stage coupler, a first and a second optical path difference generator, a first and a second optical component set, a first and a second detection device is disclosed. The first-stage coupler receives an incident light from the light source and emits first and second first-stage lights. The first second-stage coupler receives the first first-stage light and emits first and second second-stage lights. The second second-stage coupler receives the second first-stage light and emits third and fourth second-stage lights. The first/second optical path difference generator generates the first/fourth second-stage light with the first/second optical path difference. The first/second optical component set emits the second/third second-stage light to a first/second position of an eye and receives a first/second reflected light. The first/second detector receives a first/second detection light.

Abstract: An optical biometer includes a light-source module, a light-splitting module, a reference-arm, a sensing-arm and a sensing module. The light-source module emits incident-light. The light-splitting module, disposed corresponding to light-source module, divides the incident-light into reference light and sensing light. The reference-arm, disposed corresponding to light-splitting module, generates a first reflected-light according to the reference light. The sensing-arm, disposed corresponding to the light-splitting module, emits the sensing light to the eye and receives a second reflected-light from the eye. The sensing module generates a sensing result according to the first reflected-light and second reflected-light. In a first mode, the sensing light is emitted to a first position of the eye. In a second mode, the sensing light is emitted to a second position of the eye. The incident-light emitted by light-source module is partial annular light and the sensing result includes a partial annular image related to the eye.

Abstract: An optical detection system capable of providing auxiliary light source projection including an optical detection apparatus and an optical module is disclosed. The optical module and the optical detection apparatus are combined with each other in a specific combination type. The specific combination type can be a direct integration type, a bending type, a foldable type, a low height type or an attachable type. The optical module is used to provide additional auxiliary light source projection to improve a condition for testee to gaze and observe a pattern. The optical module includes a light source, a lens set and a reflecting mirror. The light source can be designed as different types of multiple light sources, such as an opposite-direction type multiple light sources or a ring type multiple light sources, to provide a uniform light source.
