Abstract
The utility model provides a laser defect detecting appearance can carry out quick audio -visual detection to the optical filtering glass defect of micron order size. Laser detector includes in proper order according to the light path that light sources, light beam become times beam expanding lens device, workstation and image acquisition system. The utility model discloses to optical filtering glass's spectral characteristic, expand high -power solid laser light source and restraint to handle, CCD high definition camera is lighted the defect and is amplified and appears on the computer, defect short -term test among the nimble optical filtering glass that realizes awaiting measuring and detection effect's comparison conveniently to the realization detects the optical filtering glass internal defect of micron order size, and smelt production and quality control provides the support for optics glass, and utility model structure is compact, and resolution ratio is effectual.
Description
Technical field
The utility model relates to a kind of laser detecting apparatus, particularly relates to a kind of laser detecting apparatus that can carry out quicklook detection to the filter glass defect of micron order size.
Background technology
Optical glass is the critical elements in optical tooling system, and its performance has very important impact to whole system.Because optical glass inner defect such as bubble, calculus produced in the process of melting produces the impact in various degree such as absorption, scattering and focusing to the light beam in optical system, and domestic and international correlation report only relies on the original detection means such as spotlight and engineering microscope to detect now, spotlight beam is second-rate, dispersion angle is bigger than normal belongs to complex light, the efficiency of engineering microscopic examination is low, can not meet production on-line checkingi.
Particularly for only to the reasonable filter glass of light wave transmitance of 400-550nm wave band, its spectral transmittance only can reach 90%, therefore the primitive approach such as spotlight, engineering microscope can not meet the detection at present to filter glass defect, also lack coherent detection means, can not the defect such as bubble, calculus that filter glass interiors of products produces be detected.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of laser defect detector, can carry out the detection of quicklook to the filter glass defect of micron order size.
The technical scheme that the utility model technical solution problem adopts is: laser detecting apparatus, comprises detection light source, light beam Zooming expander device, worktable and image capturing system successively by light path.
Further, after described image capturing system, be also provided with computing machine, described computer controlled imaged acquisition system carries out Acquire and process to the defect in the testing sample arranged on the table.
Further, described detection light source adopts 515nm green light solid laser.
Further, described light beam Zooming expander device adopts level Four design, expands multiple 2-8 times continuous variable.
Further, described worktable adopts manual two-dimension adjustment platform.
Further, described image capturing system adopts high definition CCD camera, and high definition CCD camera is lighted defect amplify and presents on computers.
The beneficial effects of the utility model are: for the spectral characteristic of filter glass, process is expanded to great-power solid laser light source, CCD high definition camera is lighted defect and is amplified and presents on computers, flexibly the defect realized easily in filter glass to be measured detects and the comparison of Detection results fast, thus realize detecting the filter glass inherent vice of micron order size, for optical glass melting production and quality control provide support, utility model compact conformation, resolution effect is good.
