The utility model can realize simultaneous detection to photoelectric signals of a plurality of channels, thereby remarkably saving the testing time, eliminating an optical filter plate, and diminishing the size of the detection unit; moreover, the utility model further solves the problem of difference among the signals of the channels caused by the spectral sensitivity of the detector, thereby facilitating the debugging of the entire photoelectric system.

Description

Integrated detector

Technical field

The utility model relates to a kind of detector, relates in particular to a kind of detector of integrated form, can be applied to fields such as Photodetection system, elemental analysis system, medical science biochemical analyzer, medical science enzyme micro-plate reader device.

Background technology

At present, the detector of selling on the market acts on singlely, and consuming time longer, volume is bigger, uses inconvenience.With the medical science biochemical analyzer is example, need test the absorption spectrum of blood respectively at 8 spectral bands such as 340nm, 380nm, 405nm, 492nm, 510nm, 546nm, 578nm, 630nm usually.

For this reason, need to use single wave band filter and combinations of detectors, provide the detectable signal of each wave band respectively.Various filters are placed in the sheet dish, need constantly carry out conversion during test.It is longer that this makes that test process expends time in, and the volume of filter dish is bigger simultaneously, brings inconvenience.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, improves the operating efficiency of Photodetection system and the convenience of electro-optical system debugging.

In order to realize above-mentioned purpose of the present utility model, the utility model provides a kind of integrated detector, comprises the printing opacity substrate, and the upper surface of described printing opacity substrate is integrated with the filter more than 2, and the lower surface of described printing opacity substrate is bonded with multiunit detector.

According to preferred version of the present utility model, the upper surface of described printing opacity substrate is integrated with 8 filters, and described 8 filters be arranged in parallel side by side.

According to preferred version of the present utility model, described multiunit detector is a cmos detector.

According to preferred version of the present utility model, described multiunit detector is the silicon photodiode array multiunit detector.

According to preferred version of the present utility model, below each described filter, all dispose the decay film.

According to preferred version of the present utility model, between each described filter, be provided with separator.

According to preferred version of the present utility model, the overall dimension of described integrated detector is 12mmX12mm, and light-receiving area is 10mmX10mm.

According to preferred version of the present utility model, described printing opacity substrate is made by optical glass.

Compared with prior art, advantage that the utility model had and beneficial effect are:

1. can realize surveying simultaneously the photosignal of a plurality of passages, obviously save the testing time;

2. can save the filter dish, dwindle the volume of probe unit;

3. the utility model is for the difference problem of each channel signal of solving detector spectrum sensitivity and being caused, make that the debugging of overall optical electric system is more convenient, according to detector at the response sensitivity of each wave band at each configuration of cells decay film, photosignal to each passage is regulated, the initial value that can make a plurality of wavelength signals is near consistent, make Circuits System be in the good operation point, all be in approaching level thereby reach multiple signals;

4. the utility model can also will be provided with separator at the sidewall of each unit, so that eliminate the signal cross-talk between each unit.

Description of drawings

Fig. 2 is the assembled state schematic perspective view of the utility model integrated detector preferred embodiment.

Embodiment

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

As depicted in figs. 1 and 2, the integrated detector according to the utility model preferred embodiment comprises: printing opacity substrate 2; Be integrated in the filter more than 2 of printing opacity substrate 2 upper surfaces; Be bonded in the multiunit detector 3 of printing opacity substrate 2 lower surfaces.

Printing opacity substrate 2 can be shapes such as square, rectangle, and the material of printing opacity substrate 2 is unrestricted, can adjust in goal of the invention scope of the present utility model, and preferably, printing opacity substrate 2 is made by optical glass material.

Preferably, can be integrated with 8

filter

1A, 1B, 1C, 1D, 1E, 1F, 1G and 1H at the upper surface of printing opacity substrate 2, and

filter

1A, 1B, 1C, 1D, 1E, 1F, 1G and 1H be arranged side by side in parallel.Pass through this set, the utility model can realize surveying simultaneously the photosignal of 8 passages, obviously the testing time can be saved, simultaneously can save the filter dish, dwindle the volume of probe unit, therefore greatly improve the operating efficiency of Photodetection system, and improved the convenience of electro-optical system debugging.

Be noted that, though 8 filters have been shown among Fig. 1 and Fig. 2, the utility model is as limit, but can adjust according to actual conditions, for example, integrated detector of the present utility model can comprise 2,3,4,5,6 or 7 filters.

The kind of multiunit detector 3 is unrestricted, can adjust in goal of the invention scope of the present utility model, and preferably, multiunit detector 3 can be cmos detector or silicon photodiode array multiunit detector.On multiunit detector 3, be formed with a plurality of leg 6, be used for being electrically connected with circuit board.

Be the approaching unanimity of the initial value that makes each wavelength signals, make Circuits System be in the good operation point, preferably, can be according to the response sensitivity configuration decay film 4 (there is shown 8 decay films 4) of detector below each filter 1 at each wave band, regulate with photosignal, thereby the photosignal that reaches more than 2 all is in approaching level each passage.

In order to eliminate the signal cross-talk between each filter 1,, can between each filter 1, separator 5 be set according to preferred version.

The overall dimension of integrated detector of the present utility model is preferably 12mmX12mm, and light-receiving area is preferably 10mmX10mm.
