Problems solved by technology

Although this solution has improved and improved compared with the original technical solution, it reduces the action of turning over and closing the cover, and speeds up the height verification speed, but it still needs to repeatedly pull the handle and repeat the test many times, and it still costs a certain amount of money. time
[0007] In short, in order to accurately adjust the 100% T and 0% T of the instrument, the existing technology require

Embodiment Construction

[0024] The present invention will be described in detail below with reference to the accompanying drawings.

[0025] An automatic light gate device for a spectrophotometer, in the receiving chamber 4 next to the sample chamber 7, between the double-sided convex lens 6 and the photoelectric receiver 5, a permanent magnet 13 that can move up and down is set, and the permanent magnet 13 Electromagnetic coil 12 is arranged on the upper side, the bottom of permanent magnet 13 is connected with light gate 15, and the below of light gate 15 is positioning seat 16. The electromagnetic coil 12 is connected to a power supply by a "spectroscopic key" button switch arranged on the spectrophotometer case 2 . The light gate 15 is a baffle plate on which a light hole 14 is opened.

[0026] With this technical solution, the light gate 15 and the permanent magnet 13 connected as one are usually in the "falling" position due to their own weight, so that the light gate 15 is in the open state, ...

Abstract

The invention relates to an improved component structure of a spectrophotometer as a scientific analysis experimental instrument, in particular to a verifying mechanism which is used for automatically regulating 0 percent Tau and 100 percent Tau before the spectrophotometer is used. An automatic optical gate device of the spectrophotometer comprises a receiving darkroom (4) positioned beside a sample chamber (7), a biconvex lens (6) and a photoelectric receiver (4) are sequentially arranged in the receiving darkroom (4) on the light incident direction of an optical gating, a permanent magnet (13) which can move up and down is arranged between the biconvex lens (6) and the photoelectric receiver (4), an electromagnetic coil (12) is arranged above the permanent magnet (13), the lower part of the permanent magnet (13) is connected with an optical gate (15), and a positioning seat (16) is arranged below the optical gate (15). The invention has convenient use, fast operation, high automation degree and strong accuracy, thereby being a spectrophotometer automatic power-on verifying mechanism which has practical value.

Description

(1) Technical field [0001] The invention relates to an improved component structure of a spectrophotometer, a scientific analysis experiment instrument, and particularly relates to a verification mechanism for the spectrophotometer to automatically adjust "0%τ" and "100%τ" before use. (2) Background technology [0002] It is well known that a spectrophotometer can perform qualitative and quantitative analysis of sample substances in the ultraviolet-visible-infrared spectral region. It is one of the commonly used spectral analysis instruments in physical and chemical laboratories. It uses an advanced blazed grating monochromator with high wavelength accuracy. Good monochromaticity, low stray light, etc., adopts microcomputer measurement system, high τ-A conversion accuracy, and has automatic adjustment of 0% and 100%, concentration factor setting, concentration direct reading, and serial data printer can be selected Perform data printing function. Widely used in medicine and...
