Laser Calorimetric Absorption Measurement Instrument
The Laser Calorimetric Absorption Measurement Instrument (LC-2000) is an optical testing device based on the laser calorimetry method, designed to measure weak absorption in optical components. By irradiating the optical component with a pump laser and using a high-precision temperature detector to measure the temperature in the irradiated area, the instrument obtains absorption data of the component at the specified laser wavelength.
The LC-2000 is suitable for detecting and analyzing the absorption rates of various optical coatings and optical components. It supports precise measurements in ultraviolet or infrared bands according to customer requirements, providing critical guidance for optical material quality control in production.
Deep Ultraviolet (DUV) Laser Calorimetric Absorption Measurement Instrument
The Deep Ultraviolet Laser Calorimetric Absorption Measurement Instrument (LC-DUV-2000) is an optical testing device based on the laser calorimetry method, specifically designed for deep ultraviolet light sources used in the semiconductor industry.It uses a DUV laser to irradiate optical components and measures temperature changes via a high-precision detector to determine absorption characteristics at the specified wavelength.
The LC-DUV-2000 is ideal for detecting and analyzing low-absorption optical coatings and components. The typical pump laser wavelength is 193nm or 266nm (customizable), enabling precise measurements in the deep ultraviolet range. It plays a vital role in guiding optical material quality control.
