Description

Technical Field

[0002] The transmittance of an optical lens refers to the ratio of the radiant flux emitted from the optical lens to the radiant flux projected onto the optical lens. It is an important indicator of the energy transmission of the optical lens and can directly reflect the optical properties of the material.

[0003] When testing the transmittance of optical lenses, existing optical testing instruments are suitable for light beams incident vertically on optical lenses or incident at small angles.

Since the receiving aperture of the receiving detector is usually small, if the light beam is greatly offset after passing through the optical lens, it will be out of the receiving range, and the receiving detector can only receive a part of the radiation light or not receive it at all, resulting in inaccurate testing.

[0024] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0025] See also Figure 1As shown, according to an embodiment of the present application, a transmittance testing device is provided, including an operating table 1, a light-emitting component 2 and a receiving component 3, the light-emitting component 2 and the receiving component 3 are arranged on the operating table 1, a sample to be tested is provided on the output light path of the light-emitting component 2, the receiving component 3 is located on the side of the sample to be tested away from the light-emitting component 2, and the position of the receiving component 3 is adjustable.

[0026] By setting the position of the receiving component 3 on the operating table 1 to be adjustable, the deviation of the light beam passing through the sample to be tested can be corrected so that the receiving component 3 can be directly in the outgoing light path of the sample to be tested, ensuring that the light beam passing through the sample to be tested can be received by the receiving component 3, thereby improving the accuracy of the test results.

[0027] The sample to be tested may be an optical lens made of glass, resin, crystal or other materials, and the transmittance testing device is used to test the ability of light to pass through the optical lens to verify the optical properties of the material.

[0028] The transmittance test device includes an operating table 1, which can be a porous metal plate. The operating table 1 is a workbench of the transmittance test device, and the operating table 1 is used to carry the sample to be tested, the light-emitting component 2, and the receiving component 3. It can be understood that by setting the operating table 1 as a porous metal plate, it is convenient to install the sample to be tested, the light-emitting component 2, the receiving component 3 and other components on the one hand, and on the other hand, it can reduce the weight of the transmittance test device and make it easy to carry.

[0029] Specifically, the sample to be tested is arranged between the light-emitting component 2 and the receiving component 3, the output end of the light-emitting component 2 is arranged toward the sample to be tested, the light-emitting component 2 is used to emit a light beam to the sample to be tested, the receiving end of the receiving component 3 is arranged toward the sample to be tested, and the receiving component 3 is used to receive the light beam passing through the sample to be tested.

[0030] The light emitting component 2 may be a wide spectrum halogen lamp.

[0031] Specifically, the light emitting component 2 includes an emitting optical fiber 21 and a first bracket 22 . The emitting optical fiber 21 is used to connect to a halogen lamp light source to achieve point light source output. The first bracket 22 is disposed on the operating table 1 and is used to support the emitting optical fiber 21 .

[0032] The receiving component 3 may be a spectrometer, which can simultaneously receive light of multiple wavelengths, specify the wavelength to be measured, compare the light intensity before and after passing through the sample to be tested, and calculate the transmittance of the sample to be tested.

[0033] Specifically, the receiving component 3 includes a receiving optical fiber 31 and a second bracket 32 ​​. The receiving optical fiber 31 is used to connect to the spectrometer to transmit the received light beam to the spectrometer for detection. The second bracket 32 ​​is disposed on the operating table 1 and is used to support the receiving optical fiber 31 .

[0034] Among them, a clamping fixture is arranged on the operating table 1, and the clamping fixture is used to clamp the sample to be tested.

[0035] Specifically, the clamping fixture and the light emitting component 2 are arranged relatively to each other along the length direction of the operating table 1 and are relatively fixed to the operating table 1 , which can ensure that the sample to be tested is located on the emission light path of the light emitting component 2 .

[0036] The outgoing light path of the light emitting component 2 is the propagation path of the light beam emitted by the light emitting component 2 .

[0037] Among them, the receiving component 3 is arranged on the side of the sample to be tested away from the light-emitting component 2 along the length direction of the operating table 1. The position of the receiving component 3 on the operating table 1 along the width direction of the operating table 1 is adjustable to ensure that the receiving optical fiber 31 is aligned with the output light path of the sample to be tested.

[0038] The outgoing light path of the sample to be tested is the propagation path of the light beam passing through the sample to be tested.

[0039] Specifically, when the light beam emitted by the light-emitting component 2 is incident on the sample to be tested vertically, that is, the incident angle of the light beam entering the sample to be tested is 0°, adjust the receiving component 3 to the first position; when the light beam emitted by the light-emitting component 2 is incident on the sample to be tested at a large angle, that is, the incident angle of the light beam entering the sample to be tested is greater than 0°, and the sample to be tested has a large thickness, adjust the receiving component 3 to the second position.

[0040] Among them, when the receiving component 3 is located at the first position, the receiving component 3 is arranged on the operating table 1 along the length direction of the operating table 1 opposite to the sample to be tested and the light-emitting component 2; when the receiving component 3 is located at the second position, the receiving component 3 is arranged on the operating table 1 along the length direction of the operating table 1 staggered with the sample to be tested and the light-emitting component 2. It should be noted that the distance between the first position and the second position in the width direction of the operating table 1 is the offset caused by the light beam passing through the sample to be tested. In the present application, by setting the position of the receiving component 3 on the operating table 1 to be adjustable, the offset caused by the light beam passing through the sample to be tested can be corrected, so that the transmittance testing device is not only suitable for the test scenario where the light beam is incident vertically on the product to be tested, but also suitable for the test scenario where the light beam is incident on the product to be tested at a large angle and the product to be tested has a large thickness.

In the present application, the light beam emitted by the transmitting optical fiber 21 propagates toward the sample to be tested through the first light-transmitting hole 221, and the light beam passing through the sample to be tested enters the receiving optical fiber 31 through the second light-transmitting hole 321.
