The optical performance testboard for an optical membrane can ensure reflection light to return back completely along incident light paths, can easily ensure verticality and repeatability to be better, and is more accurate in tested optical curves.
Description
Technical field
The utility model relates to a kind of device that is used for the optical property of detection optical diaphragm.
Background technology
At present; Continuous development and universal use the along with optical fiber communication technology; Wherein relevant device and equipment and the core diaphragm (chip) thereof of WDM (wavelength-division multiplex) technology begun to get in a large number backbone network and the MAN that optical fiber lays; The production use amount of WDM diaphragm is increasing, and manufacturing enterprise has proposed an urgent demand to testing WDM diaphragm optical property efficiently, accurately.General test WDM reflectance spectrum is used double-fiber collimator, and an optical fiber is as incident light, and another optical fiber receives reflected light.Owing to use two optical fiber, can not guarantee that reflected light returns along input path fully, so the reflectance spectrum curve of test is not accurate enough; In addition; In the test of WDM diaphragm reflectance spectrum, need to guarantee that WDM diaphragm lower surface is vertical as far as possible with travel path of incident light, more near 90 degree; The test result of reflectance spectrum is accurate more; Because it is vertical that two optical fiber are not easy to guarantee, so test reflectance spectrum curve repeatability is bad, test result is not accurate enough.
The utility model content
The purpose of the utility model is to avoid deficiency of the prior art and provides a kind of reflected light that can guarantee to return along input path fully, guarantees easily vertically, and repeatability is better, the optical curve of test blooming piece optical performance test platform more accurately.
The purpose of the utility model realizes through following technical scheme:
Blooming piece optical performance test platform; Comprise the diaphragm objective table; The diaphragm objective table is provided with the aperture that can place diaphragm to be measured; Below described diaphragm objective table, be provided with the single fiber collimating apparatus of alignment apertures, the below of single fiber collimating apparatus is provided with coupling mechanism, and the bottom of coupling mechanism is connected to light source and spectrum test analytical equipment.
Described single fiber collimating apparatus is installed on the collimator adjustment frame.
Owing to adopted above-mentioned structure, the WDM diaphragm is placed on the aperture during use, and light sends from light source; Through optical fiber, get into coupling mechanism, send from coupling mechanism again; Get into the single fiber collimating apparatus, send from the single fiber collimating apparatus, through the aperture on the diaphragm objective table; Incide the lower surface of WDM diaphragm, produce reflected light; Reflected light returns along input path, incides the single fiber collimating apparatus, comes out to get into coupling mechanism from the single fiber collimating apparatus, and the reflected light that coupling mechanism receives inserts the spectrum test analytical equipment, can carry out the reflectance spectrum analysis to diaphragm.
The utlity model has following beneficial effect:
(1) through changing to double-fiber collimator the single fiber collimating apparatus, incident light and reflected light have guaranteed that all through same optical fiber reflected light returns along input path fully, so the reflectance spectrum curve of test is more accurate;
(2) in the test of WDM diaphragm reflectance spectrum, need to guarantee that WDM diaphragm lower surface is vertical as far as possible with travel path of incident light, near 90 degree, the test result of reflectance spectrum is accurate more more; Through changing pair optical fiber into single fiber, in regulating the assurance input path process vertical, guarantee more easily vertically among the present invention, so test reflectance spectrum curve is repeated better with WDM diaphragm lower surface.
Description of drawings
Utilize accompanying drawing that the utility model is described further; But the embodiment in the accompanying drawing does not constitute any restriction to the utility model; For those of ordinary skill in the art, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to following accompanying drawing.
Fig. 1 is the structural representation of blooming piece optical performance test platform.
Embodiment
Be described in further detail below in conjunction with the embodiment of accompanying drawing the utility model.
As shown in Figure 1; The described blooming piece optical performance test of the utility model platform comprises diaphragm objective table 1, and diaphragm objective table 1 is provided with the aperture 2 that can place diaphragm to be measured; Below described diaphragm objective table 1, be provided with the single fiber collimating apparatus 3 of alignment apertures 2; Described single fiber collimating apparatus 3 is installed on the collimator adjustment frame 7, and collimator adjustment frame 7 can be three-dimensional adjustable shelf, in order to regulate the position of single fiber collimating apparatus 3.The below of described single fiber collimating apparatus 3 is provided with coupling mechanism 4, and coupling mechanism 4 is used for separating incident light and reflected light.The bottom of coupling mechanism 4 is connected to light source 5 and spectrum test analytical equipment 6.
When the utility model used, the WDM diaphragm was placed on the aperture 2, and light sends from light source 5; Through optical fiber, get into coupling mechanism 4, send from coupling mechanism 2 again; Get into single fiber collimating apparatus 3, send from single fiber collimating apparatus 3, through the aperture on the diaphragm objective table 12; Incide the lower surface of WDM diaphragm, produce reflected light; Reflected light returns along input path, incides single fiber collimating apparatus 3, comes out to get into coupling mechanism 4 from single fiber collimating apparatus 3, and the reflected light that coupling mechanism 4 receives inserts spectrum test analytical equipment 6, can carry out the reflectance spectrum analysis to diaphragm.
In a word; The above-mentioned preferred implementation though the utility model has been given an example; But should explain; Though those skilled in the art can carry out various variations and remodeling,, otherwise all should be included in the protection domain of the utility model only if such variation and remodeling have departed from the scope of the utility model.
