The sample bench device for focusing by utilizing the lens group has the characteristics of adaptability to the detection of jewels with different dimensions and higher transmitted spectrum flexibility, small volume, low cost and the like.
Description
Technical field
The utility model relates to a kind of sample table device that jewel is measured that is used for, particularly a kind of sample table device that is used for the measurement of jewel transmitted spectrum that utilizes lens combination to focus on.
Background technology
The monetary value of diamond, pearl and other precious jewel can have very big difference according to the aesthetic features of each jewel.This characteristic for example comprises that color, transparency, cutting, shape, brightness or the like are the important subjective factors of its value of decision.For example, the jewel of usually finding same size and weight is owing to the influence of these subjective factors is worth very different.Thereby unified measurement of these characteristics is the reliable first steps estimated of monetary value that obtain jewel.
Along with the develop rapidly of jewelry people technology for making, to current to gemstone testing work require increasingly highly, the difficulty of gemstone testing work is also increasing.
In traditional crystal structure analysis instrument; What generally use is transmission spectrum measurement instruments, carries out the light path adjustment through using combination of lenses, makes it jewel or the crystal of transmission through needing to measure; Adapt to undersized gem crystal; And effectively assemble the light path energy, thus obtain more high measurement sensitivity, be widely used in, evaluation, the testing process of sample such as crystal.
But because the jewel size is little, price is high, and shape various (being commonly referred to conformal) is measured so the sample stage that conventional transmitted spectrum uses is not suitable for the jewel transmitted spectrum.Conventional transmitted spectrum is measured and is generally adopted absorption cell absorption plant, light path horizontal positioned, jewel can't be clamped in the sample stage, uses inconvenient.
Summary of the invention
In order to overcome the above-mentioned technological deficiency that prior art exists, the utility model discloses a kind of sample table device that is used for the measurement of jewel transmitted spectrum that utilizes lens combination to focus on.
The utility model for the technical scheme that solves its technical matters employing is: a kind of sample table device that is used for the measurement of jewel transmitted spectrum that utilizes lens combination to focus on; This device is whole to have light shield, have the pedestal of level and is vertically mounted on the equipment supporter that can regulate on the horizontal base, and this device also comprises the incident optical interface that is installed in successively from top to bottom on the equipment supporter 1, first convex lens 2, quartz glass plate 3 (placement jewel), second convex lens 4 and transmitted spectrum signal reception optical fiber interface 5.
Wherein: incident optical interface 1 output beam; Focus on through 2 pairs of light beams of first convex lens; Light beam focuses on and shines the jewel that is placed on the quartz glass plate 3, and through behind the jewel sample, light is focused on by second convex lens 4 once more; Shine the transmitted spectrum signal and receive on the optical fiber interface 5, and subsequently by spectral measurement instrument receiving and analyzing.
The utility model has following advantage and beneficial effect:
1, with vertical light path mode, jewel lies in a horizontal plane on the transparency silica glass plate, can place the small size jewel, is difficult for simultaneously moving or losing.
2, focus on lens combination, make light focusing pass through the jewel sample, effectively the collected light energy reaches higher transmitted spectrum sensitivity.
3, whole instrument can be regulated, and adapts to the jewel sample of different-thickness, convenient focusing; And apparatus is through connecting fiber optic conduction lighting source and optical signal transmissive, and integral body has light shield, prevents parasitic light; It is little that sample table device has a volume, lower-price characteristic.

Embodiment
Be described further below in conjunction with the embodiment of accompanying drawing the utility model:
A kind of sample table device integral body that is used for the measurement of jewel transmitted spectrum of utilizing lens combination to focus on has the pedestal of light shield, level and is vertically mounted on the equipment supporter that can regulate on the horizontal base; This device also comprises incident optical interface 1 incident optical interface 1 output beam that is installed in successively from top to bottom on the equipment supporter; Focus on through 2 pairs of light beams of first convex lens; Light beam focuses on and shines the jewel that is placed on the quartz glass plate 3, and through behind the jewel sample, light is focused on by second convex lens 4 once more; Shine the transmitted spectrum signal and receive on the optical fiber interface 5, and subsequently by spectral measurement instrument receiving and analyzing.
In this example, incident optical interface 1 specification is the SMA905 optical fiber interface, and distance first convex lens 2 distances are 30mm, and the focal length of first convex lens 2 and second convex lens 4 is 15mm, and diameter is 10mm.The distance of quartz glass plate 3 distance first convex lens 2 and second convex lens 4 is 30mm.The light of incident optical outgoing is focused on the quartz glass plate 3 by first convex lens 2; Place the jewel sample on the quartz glass plate 3; Through adjusting the distance of first convex lens 2 and quartz glass plate 3, make light focusing to the jewel sample, the transmitted light behind the transmission jewel sample; Being focused on the transmitted spectrum signal once more by second convex lens 4 receives on the optical fiber interface 5; Receive the transmitted spectrum signal by receiving optical fiber, the spectral instrument that gets into subsequently carries out spectral analysis, and its specification that receives optical fiber interface 5 is the SMA905 optical fiber interface.Receive on the optical fiber in order to guarantee that light after the transmission can correctly focus on, can suitable small adjustment second convex lens 4 with transmitted spectrum signal reception optical fiber interface 5 between distance, to adapt to the jewel sample of differing heights.
This device has the detection of suitable different size jewel, higher transmitted spectrum sensitivity, and convenient focusing, integral body has light shield, prevents parasitic light, and it is little that sample table device has a volume, lower-price characteristic.
