Temperature control with IR Sensor

Postby mecanicu » Sun Sep 25, 2016 6:30 pm

Hello, long time since i post here.
I was busy with a lot of interesting project's. But i did't give up on my 3d sls project.
I manage to buy more item's for the project. One is a Optris CT LT20 Infrared sensor (i wanted this one because is integrated in BeamConstruct software) and i was wandering if it's possible to integrate this sensor in the galvo system. A want to switch my pilot laser with this IR sensor, I'm attaching a picture of the laser shatter system (this is located betwin laser and galvo head), were the pilot laser is located. This shatter act's as a 90angle mirror when it''s closed.

... what's your plan for the IR-sensor?

Hello VDX.

...Monitor the temperature exactly at same spot size as galvo system. I want to be able to monitor the temperature between layer's (when the laser is off)

... sounds interesting -- how fast ist the measurment and how small/big is the measured area on the surface?

Maybe you should check the losses per shutter- and galvo-mirrors to see, if it's efficient enough ...

Response time is 150ms. Distance/Spot size ratio is 20/1, so for example spot size is 10mm at 200mm distance.
I dont know if my existent optics and galvo mirrors can work with this IR sensor.
Maybe you know a software that can design and calculate a optical system....
