CI Semi offers top quality optical interfaces and accessories for its NTM product line to give a complete range of solutions for non-contact temperature monitoring.
For both lightpipes and remote optics, CI Semi customizes the interface according to the customer’s specifications.


Lightpipes of various lengths are available with diameters ranging from 1 to 4 mm, in both sapphire and quartz. In cases where a lightpipe cannot be inserted into the chamber, remote optics can be used to measure the temperature via the chamber viewport.
The remote optics are designed according to the specific chamber geometry and dimensions. CI's experience of over 10 years of installing NTM products in more than 1000 chambers ensures the best and most cost?effective solutions for every application.
