CureUV Lens Transmission Meter LTM1B

CureUV Lens Transmission Meter is designed to precisely measure the transmittance of various transparent substances using advanced light sources and sensors. This device utilizes infrared 850nm and 940nm, and visible 550nm light sources to illuminate the material under test. Dedicated sensors then capture the incident light intensity of these sources and measure the light that passes through the substance.

Key Specifications:

• Minimum test object size: Ø0.019 in

• Infrared: 850nm and 940nm two-way test

• Visible light: central wavelength 550nm

The percentage of transmittance is determined by comparing the intensity of transmitted light to the incident light. This is a critical measurement in evaluating the effectiveness and excellence of transparent materials.

In the context of smartphones, which incorporate light and distance sensors, the Lens Transmission Meter plays a critical role. These sensors automatically adjust screen brightness based on ambient light and detect the distance to the user's face during calls to prevent accidental screen touches. The accuracy of these functions depends on the infrared penetration capability of the lens, particularly through the small holes designated for sensors and the larger hole for the camera.

The Lens Transmission Meter ensures that these lenses meet stringent transmittance requirements, ensuring optimal performance of smartphone sensors. It provides essential data on infrared transmittance for both the sensor holes and the camera lens, crucial for maintaining high-quality functionality of modern smartphone devices.
