薄膜生产时需要测量雾度和透光率，现在连颜色也可以测了。就是它，没错！

• Optical System: Dual Beam Spectrophotometer with Integrating Sphere
• Spectral Range: 400-700nm
• Wavelength Interval: 10nm
• Effective Bandwidth: 10nm equivalent triangular
• Light Source: Pulsed xenon lamp
• Lamp Life: >1 million flashes
• Illuminant/Observer: D65/10°, C/2°
• Color Scales: CIE L*a*b*, HunterLab, Yxy, XYZ and their difference plus DE*, DE
• Indices: ASTM E 313 Yellowness, Y Transmission, Haze
