Embodiment 1

[0023] see Figure 1 to Figure 5 , the present invention provides a technical solution: a device for measuring optical characteristics, including a base plate 1 and an integrating sphere 2, and a measuring host connected to the integrating sphere 2. The upper surface of the base plate 1 is connected with a central axis 3 for fixed axis rotation, and the central axis The top of the 3 is fixedly connected with a turntable 4, and the upper surface of the turntable 4 is provided with several clamping components, and also includes a clamping speed for driving each clamping component to gradually decrease when it is gradually approaching the clamped object, and synchronous The drive part that drives the turntable 4 to rotate intermittently. The drive part includes a motor 11 fixedly connected to the upper surface of the base plate 1, and a housing 12 fixedly connected to the lower surface of the turntable 4. The drive shaft of the motor 11 passes through the intermittent rotating par...

Embodiment 2

[0028] In order to reduce the frictional resistance between the rack plate 16 and the disc 24 , further, the abutting portion includes a ball 25 disposed at the bottom of the rack plate 16 .

[0029] Further, the linkage components include a reciprocating screw 26 fixedly rotatably connected to the upper surface of the base plate 1, and a limit post 27 fixedly connected to the upper surface of the base plate 1. The surface of the sleeve 28 is provided with an opening for the limit column 27 to pass through and be slidably connected with it. The reciprocating screw 26 is connected to the drive shaft of the motor 11 through the pulley transmission part 29. During the continuous rotation of the motor 11, the pulley is driven The component 29 will drive the reciprocating screw rod 26 to rotate, and then make the reciprocating screw sleeve 28 under the limit of the limit column 27, so that the reciprocating screw sleeve 28 can drive the integrating sphere 2 to reciprocate up and dow...

Abstract

The invention discloses an optical characteristic measurement device, which relates to the technical field of optical characteristic measurement, and comprises a bottom plate, an integrating sphere, and a measuring host connected to the integrating sphere. The top of the central shaft is fixedly connected with a turntable, and the upper surface of the turntable is provided with several clamping parts. Under the action of the intermittent rotating parts, the central shaft, the turntable, and the clamping parts will automatically stagnate for a period of time, and then When the integrating sphere moves down and covers the sample directly below it, so as to cooperate with the measuring host, the quantum efficiency of the sample, which is an important optical characteristic parameter index, can be measured. Place the sample so that it is not easy to touch the optical light path in the integrating sphere, which will affect the stability of the measurement.

Description

technical field [0001] The invention relates to the technical field of optical characteristic measurement, in particular to an optical characteristic measurement device. Background technique [0002] Quantum efficiency is an important parameter index of the optical properties of luminescent materials. With the continuous development of luminescent materials, especially the development of quantum dot luminescent materials, the demand for measuring equipment for quantum efficiency is increasing. [0003] However, when testing the optical characteristic parameters of the sample, the sample is often placed manually. The operation during the sample placement process is cumbersome and the optical path is easily touched, which affects the stability of the measurement. Especially for the single integrating sphere system, it needs to be continuously installed and disassembled during the test. The spherical cover, the measurement process is time-consuming, is not suitable for the meas...
