The TO-39 is a photodetector-preamplifier combination device that has high gain in low-light environments. The low-light, high-sensitivity component has a large active area that operates in the near infrared (NIR) wavelength. The device offers 500 Mohm gain with custom gains also available. The device is based on proprietary shielded amplifier electronics, having low noise and high sensitivity. The hermetically sealed component is suitable for assembly in confined spaces and applications such as fluorescence, microscopy and analytical chemistry. Storage and operating temperature ranges from -25 C to +100 C.
