This product is equipped with FIX mode which optimize configuration automatically and achieves ultra-high speed measurement of about 0.4sec.
This measurement time is half as much as our previous model.
The SR-LEDH will be met the stringent demands for high accuracy and high speed measuring, and it is suited for in use in quality control in LED module production line.
￭ High-speed measurement (0.4sec) via LAN with FIX mode.
￭ Reduced the evenness of sensitivity by our new original optical system.
￭ Slim body suitable for processing line and system equipment.
￭ Included original software development Kit.(SDK)
* Software Development Kit(SDK)
This development kit provides a convenient tool to develop LAN communication software by customer.
SDK consists of header file, library, sample program which is needed to develop LAN communication software.
You can develop network programming (socket communication programming) by calling library function in module.
The customer can also develop software using Network programming without SDK.
It is possible to control SR-LEDH by PC in the network and also possible to control several SR-LEDH by one PC.
