We describe a dual-technique laser calorimeter for measuring the absorption of dielectric thin films in the UV region below 400 nm. The instrument measures the temperature rise and absorption of a sample simultaneously by two independent techniques, namely, a resistance thermometer and a temperature transducer. The absorption constant β and extinction coefficient κ of Sb2O3 and ZrO2 films at 308 and 337 nm are measured by using the calorimeter. The principle, construction, and application of the calorimeter are described.
