Background technology
At present, mineralogy often utilize different minerals sample to the key character of the selective absorbing of full spectrum, visible light as Minerals identification and qualification.Known to mineral samplers carry out spectrophotometric spectra detect generally have two kinds of modes: the most frequently used is transmitted light detection method, and full spectrum, visible light enters spectroscope after being directly perforated through mineral samplers to be measured, can observe transmitted spectrum; Another kind method is reflected light detection method, after reflection and refraction occur full spectrum, visible light in mineral samplers to be measured, then enters spectroscope.In operation, these two kinds of detection modes all take the observation procedure clamped by hand, and namely light source, spectroscope and mineral samplers to be measured all rely on manual clamping.This kind of method not only inefficiency, highly relies on experience and the skill level of tester, but also there is a lot of problem:
(1), light source used is high-power fiberoptic lamp, and power consumption is large, complex structure, and optical fiber flexible pipe is very easy to damage, and the high temperature produced that works long hours can destroy mineral samplers;
(2), when the mineral samplers that clamping dimension is less, small part light can enter spectroscope through finger, is mixed into the spectrum of blood of human body in the spectrum observed, brings very large error to testing result;
(3), observation space is not airtight, has part veiling glare directly to inject spectroscopic exam hole, reduces the spectral resolution observed;
(4), in spectroscope eyepiece, observed result cannot file;
(5), the transmitted spectrum of same sample and reflectance spectrum cannot do comparative study.
The patent No. is that the utility model patent " a kind of clamping device for jewel " of ZL200320125527.4 discloses a kind of clamping device for jewel, is configured to by spectroscope gripping frame, jewel fixed mount, center link and light source gripping.Center link is extracted from jewel fixed mount, put into the axis hole needing the jewel of discriminating on the right side of jewel fixed mount, and by rotation three jewel fixed mount adjustment bolt handles, jewel is fixed in jewel fixed mount, and then center link is inserted in the right side pivot holes of jewel fixed mount, then light source is fixed on light source gripping frame, finally again spectroscope is inserted in spectroscope gripping frame central shaft hole, and makes spectroscope and soft anti-dazzling screen and jewel close contact.This utility model is only applicable to transmitted light observation, cannot use in reflected light observation method, and the optical fiber lamp heating that works long hours easily damages mineral samplers to be measured, also cannot preserve observed result.
In sum, in prior art, mineral spectra detects complicated operation, checkout equipment used easily damages; The high temperature produced during equipment runs, not only produces huge energy consumption, and is easy to damage mineral samplers, run counter to the basic norm of " Non-Destructive Testing "; Testing process is affected by the external environment greatly, causes that testing result error is large, resolution is low, and cannot file, and more the result that transmission and reflection two kinds of detection methods obtain can not be put together and carry out accurate comparative analysis.The existence of the problems referred to above, directly reduces the work efficiency of mineral spectra detection and the degree of accuracy of testing result.
