       Featuring a wide transmission range of infrared spectrum, germanium is very suitable for infrared laser applications. The spectral transmittance of germanium is very sensitive to temperature. The material absorption becomes extremely high at an ambient temperature of 100°C, making it almost opaque to light, and completely opaque at an ambient temperature of 200 °C. Since germanium contains harmful substances, operators must wear gloves, filter dust masks, chemical safety goggles, and impermeable work clothes during operation, and wash hands after operation.
