太阳墨镜不同波长下的透光率数据

透射比又叫透射系数，是透过镜片的光通量与入射光通量之比。浅色太阳镜作为装饰配镜，其左右镜片在不同波长下的透过率应尽量相等，若左右镜片透射比的标准偏差过大，长期佩戴容易导致眼睛疲劳。该实验数据为太阳镜的两只镜片在可见光下不同波数（步长为10nm）的透射率及其平均值和标准偏差，为企业关于太阳镜的研发、测试、使用提供数据支持。样品制备：将眼镜片正中位置画出一直径2cm白色圆圈作为测试区域；2.样品测试：将眼镜样品放置在样品仓内，使光源光路
可以正好透过镜片白色圆圈。取下镜片，设置区段(380nm-780nm)，进行仪器校准。仪器校准完成后，对眼镜的左右镜片分别进行透光率测试；。3.数据处理：计算左右镜片的透过率平均值X=(XR+XL)/2和标准偏差SD=√（XR-X）²+（XL-X）²

Transmittance, also known as transmission coefficient, refers to the ratio of the luminous flux transmitted through a lens to the incident luminous flux. As decorative eyewear, light-colored sunglasses require that the transmittance of the left and right lenses should be as equal as possible at different wavelengths. If the standard deviation of the transmittance between the two lenses is too large, prolonged wearing may easily cause eye fatigue.

This experimental dataset records the transmittance of the two lenses of sunglasses at different wavelengths (step size: 10 nm) in the visible light range, as well as their average values and standard deviations, providing data support for enterprises' R&D, testing and application of sunglasses.

Sample Preparation: Draw a white circle with a diameter of 2 cm at the center of the eyeglass lens as the test area;
2. Sample Testing: Place the eyeglass sample into the sample compartment, ensuring that the optical path of the light source can exactly pass through the white circle on the lens. Remove the lens, set the test range (380 nm - 780 nm) and perform instrument calibration. After the instrument calibration is completed, conduct transmittance tests on the left and right lenses of the eyeglasses respectively;
3. Data Processing: Calculate the average transmittance X of the left and right lenses using the formula X=(X_R + X_L)/2, and the standard deviation SD using the formula SD=√[(X_R - X)² + (X_L - X)²]
