USB CCD/laser spot measuring instrument with 4 C-interface neutral attenuators

Description

USB-CCD Laser Camera is a laser camera (with two high-quality C-interface attenuation sheets)
Features are as follows:
1 Photosensitive chip: 1/3 Sony 960H CCD Sensor;
2 shutter mode: the overall electronic shutter;
3 resolution: 720*576;
4 photosensitive surface: 6mmX5mm;
5 wavelength range: 190nm-1700nm (Note: the wavelength above 1100nm must be femtosecond or picosecond laser to respond)
6 Distribute 4 high-quality C-interface neutral attenuators with transmittances of 1%, 5%, 1%, 25%, respectively
7 internal automatic synchronization;
8 USB is powered separately.
9 With two high-quality C-interface attenuators, it attenuates the intensity of the incident laser beam and filters out the intensity of the light incident on the CCD.
It can measure both continuous lasers and pulsed lasers with low repetition rate (internal synchronization).
Note: The cheap USB CMOS camera on the market is also common. The sensible chip uses CMOS. Compared with CCD, it has a light sensitivity, large signal noise and poor pixel consistency. It is also used for laser spot measurement. The fatal problem is that CMOS can't measure the spot of the laser (specially pulsed laser with a repetition rate lower than 10 kHz). Because CMOS uses a rolling shutter, it uses the method of exposing and collecting the image line by line, so it can't pulse laser. The spot is completely collected at one time; instead, the CCD uses an integral shutter, which allows the entire spot image to be collected once and completely. Therefore, if it is used for laser spot measurement, please be sure to ask the type of sensor when purchasing.
