Pyroelectric Detectors

Pyroelectric detectors are thermal detectors; i.e. they create an electric signal due to temperature changes in the chip. This temperature change is caused by absorption of light. We do use LiTaO₃ and DLaTGS as pyroelectric materials. Basically such detectors cover the whole spectra. However, they are mainly used for mid-wave and long-wave infrared detection (MWIR and LWIR). In addition, the usage in the THz region seems to become more popular these days.

Advanced LTO Infrared Detectors

Advanced single channel voltage mode detectors for FTIR instruments.

High-End Ultrathin LTO Detectors

The Advanced LTO Infrared Detectors combine the benefits of existing LTO and DLaTGS detectors. With this thin design, detector performance is improved due to a 4x better signal.

The Advanced LTO Infrared Detectors offer the freedom to choose the speed that suits each application. With transmission window options that allow for various configurations, such as a KBr window that transmits up to 30 μm and is also available with a parylene moisture-protective coating. High performance can be maintained up to 1 kHz, while the detector can be used out to approximately 10 kHz.

Additionally, the Advanced LTO Infrared Detectors are tested to operate at room temperature with no depoling concerns, as is typical for DLaTGS detectors. Under increasing IR flux, high linearity is observed, as well as a high Curie temperature of 610 °C.

The Advanced LTO Infrared Detectors are ideal for FTIR spectroscopy. They can also be appropriate for the measurement and monitoring of laser power at long wavelengths.
