Dental light curing machine light intensity measuring device - light meter

Sep 13,2025

The core function of the dental light curing radiometer is to measure the light intensity of the blue light wavelength (450-490 nanometers) emitted by the light curing machine, usually in milliwatts per square centimeter (mW/cm²). Its working principle is based on the photoelectric effect: when blue light irradiates the photodetector of the radiometer, the sensor converts the light energy into an electrical signal, which is then amplified and calibrated by internal circuits, and the light intensity value is displayed in digital or pointer form.

Dental Light Curing Unit Light Intensity Measuring Device — Light Meter

In the field of dental treatment, light curing technology has become a core method for repairing tooth defects and filling cavities. The key performance indicator of the light curing unit — light intensity — directly affects the curing effect of resin materials and clinical quality. As a key device for monitoring light intensity, the dental light curing light meter provides doctors with scientific data by accurately measuring the intensity of blue light radiation, becoming an indispensable tool to ensure treatment safety and effectiveness.

1. Technical Principle: From Light Radiation to Data Quantification

The core function of the dental light curing light meter is to measure the light intensity of the blue light wavelength (450-490 nanometers) emitted by the light curing unit, usually expressed in milliwatts per square centimeter (mW/cm²). Its working principle is based on the photoelectric effect: when blue light irradiates the photodetector of the light meter, the sensor converts the light energy into an electrical signal, which is then amplified and calibrated by internal circuits, and the light intensity value is displayed in digital or pointer form.
