Tau™ SWIR
SHORTWAVE INFRARED CAMERA CORE
FLIR Tau® SWIR and broadened spectral range Tau Vis-SWIR provides outstanding short-wave infrared image quality and performance over a wide range of imaging and light level conditions. It is the ideal OEM SWIR imaging module for applications like hyperspectral instrumentation, silicon inspection, electro-optical payloads, art restoration, and portable imaging. The Tau SWIR camera incorporates the FLIR high resolution 640×512 ISC1202 Indium Gallium Arsenide (InGaAs) 15-micron pitch focal plane array (FPA) and includes several advanced camera controls features.
PRODUCT CHANGE NOTICE:
The FLIR SWIR sensor used in the Tau SWIR camera is comprised of an InGaAs detector on a silicon Readout IC in a vacuum package assembly. The window on the vacuum package assembly is a high-quality anti-reflection coated glass window. To reduce the impact of possible window defects and debris on the outer window surface, the vacuum package assembly has been modified to move the window further away from the sensor. There are no changes in camera performance with the standard C-mount lenses.
The Vacuum Package Assembly (VPA) Change
From the VPA interface document the original widow height was shown in Figure 1. The taller VPA was created to add window height to the overall assembly. The position of the sensor with respect to the mounting surface did not change. As shown in Figure 1 the distance from the sensor to the front surface of the vacuum window was 0.371 – 0.202 = 0.169. The change shown in Figure 2 changes the distance from the sensor to the front surface of the vacuum window is 0.498 – 0.202 = 0.296.
Sensor to front of window:
was 0.371 – 0.202 = 0.169
is now 0.498 – 0.202 = 0.296.
The increase in package height is small and no changes were made to the internal components of the camera. If the camera is being used with the C-Mount front cover the user should see no difference in performance. There may be some C-Mount lenses which extend well behind the C-Mount standard 17.526mm flange to image plane distance. Adequate distance should be verified before installing any lens to the camera.
