Product Description and Features MAXCAM-400UV-TE is powered by GSENSE400BSI 2-inch image sensor. In view of the inherent thermal noise of the sensor, an efficient cooling module is specially designed to make the camera sensor work at 35-40 degrees lower than the ambient temperature. An anti-fogging mechanism is designed to prevent the fogging of the sensor and filter surface at low temperature. MAXCAM-400UV-TE video and image data is transmitted through the USB3 ultra high speed transfer interface for fast preview. The basic features of MAXCAM-400UV-TE are as follows: • • • • • • • • • • • •...

Camera trigger mode support: soft trigger mode or external trigger mode. 2.4 DDR3 Buffer MAXCAM-400UV-TE has a built-in 512MB (4Gb) DDR3 buffer, which can effectively improve the stability of USB3 data transmission and ensure that the camera does not lose frames when working. 2.5 Binning The MAXCAM-400UV-TE supports additive or averaged 1x1 to 8x8 digital binning, and averaged 1x1 to 2x2 hardware binning. Hardware binning can achieve higher frame rates than software...

The camera's cooling system is cooled by TEC. It uses an external heat dissipation structure and a fan to assist heat dissipation. The working temperature can be adjusted to a specific value, and the effective cooling temperature can be lower than the ambient temperature by 30-35 C. The efficient cooling system guarantees extremely low dark current levels. The TEC system is controlled by PID algorithm, so that the TEC can be accurately adjusted to the target temperature, and the temperature deviation is 0.1 C.

Trigger function After the camera enters the trigger mode, it automatically enters the wait-for-trigger state. After receiving a trigger signal, the camera starts exposure, and starts to output image data after exposure. 5.1 Trigger signal source selection In trigger mode, the type of trigger signal source can be the trigger signal given by the software, or it can be connected by an external level signal. The external trigger signal can be input through the pin isolated by the optocoupler, or it can be input through the non-isolated tube pin input. Soft trigger delay is ms level, generally not...

Figure 17 External trigger settings In the trigger mode, the acquisition mode is divided into: single-frame trigger, multi-frame trigger, counter trigger mode. The single-frame trigger mode refers to the operation mode in which the camera receives one trigger signal, exposes once, and outputs one frame of image. Multi-frame trigger mode refers to the operation mode in which the camera receives a trigger signal and outputs multiple frames of images. Trigger number can be set in the range of 1~ 65535 . "Burst Count = 1 ” means a one-frame image output, Figure 18, "Burst Count = 3 ” means a three-frame...
