Embodiment Construction

[0012] Such as figure 1 , 2 As shown, the wide-spectrum light beam emitted from the lamp source 1 is transformed into a single-wavelength polarized light beam through the dual modulation disc 2, the monochromator 3, the filter 4, and the polarizer 5, and becomes a probe light incident through the heating device 9. Photodetector 12; heating device 9 is positioned on the rotatable sample stage 10, and sample stage 10 is connected with detector rotating arm 14 by rotating shaft, and photodetector 12 is on the other side of detector rotating arm 14, and detector rotating arm 14 is driven by a stepper motor 13, and the photometer is controlled by a controller; the heating device 9 has a heating device chassis 9.4, and the heating device chassis 9.4 is connected with a ceramic gasket 9.3 and a heating base 9.2 in sequence, and a heating device is provided in the heating base 9.2. Tube 9.5, thermocouple 9.6, ceramic gasket 9.3, and heat shield 9.1 are arranged outside the heating ba...

Abstract

The invention discloses sample cell temperature controllable spectrophotometer. The wide spectrum light beam emitted from the light source is changed into one light wavelength light beam through binary modulation plate, monochromator, filter, and polarizer, and changed into detecting light shoot into photoelectric sensor through heating device. The heating device is fixed on rotatable specimen stage. The specimen stage is connected to detector tumbler by rotating shaft. The photoelectric sensor is at the other side of the tumbler. The tumbler is drove by stepper motor. Photometer is controlled by controller. The invention solves the problem that spectrophotometer cannot measure optics sample transmission reflectance characteristics at a certain constancy of temperature; or the transmission reflectance characteristics change with the temperature. It can apply in optical element with high using temperature demand, such as optical thin film transmission reflectance ratio measuring.

Description

technical field [0001] The invention relates to a spectrophotometer with controllable sample chamber temperature. Background technique [0002] The transmittance or reflectance of an optical element can be measured with a spectrophotometer. A spectrophotometer consists of a light source, a monochromator, and a detector. When working, the light beam emitted by the light source is turned into single-wavelength light by the monochromator, and then the detector measures the light energy of the single-wavelength light passing through the optical element or reflected by the optical element to obtain the transmittance or reflectance of the optical element. [0003] The transmittance and reflectance of general optical elements are considered constant. This is mainly due to the fact that general optical components are used at room temperature. Therefore, the temperature of the optical sample in the spectrophotometer is not controlled, but changes with the ambient temperature. How...
