Overview

About the ZX20

The ZX20 is a precision structured light laser module for demanding image processing, and it is available in a wide range of wavelengths. Robot alignment of every optical component during automated production yields a typical boresight error below 0.8 mrad in fixed focus form, while tool-free focusing means the laser can be optimally adjusted to different working distances. The ZX20 can operate reliably in harsh environments due to its robust design.

Eight wavelengths are available, from 405 nm and 450 nm blue through 520 nm green and 640 to 685 nm red to 785 nm and 830 nm infrared, with output power up to 200 mW depending on the laser diode. Fan angles of 5 and 10 degrees sit alongside 20 to 90 degrees for uniform lines, with line straightness under 0.05 percent.

Blue and green versions take 9 to 30 VDC, red and infrared 5 to 30 VDC, both on a 5-pin M12 plug. I2C and RS-232 at 5 V drive a graphical user interface for status query, power control, intensity and a weighted end of life indication, and TTL modulation reaches 400 kHz. The stainless steel head is 20 mm in diameter and IP 67 rated.
