Welcome to khs-instruments

Since 1993 we design and manufacture hardware and corresponding software for our customers in industry, universities and research institutes.

Our products are designed to run 24/7/365 and include line cameras, spectrometers and instrument controllers.

It is our business to find the best solution together with our customers.

We do not use USB to serial converters. We have our own USB firmware stack together with signed W10/W11 USB drivers. So there is never the need to adjust serial device numbers.

USB2-NMOS 512 Camera with new Line Management:

The new USB2-NMOS 512 line  camera provides not only 
3.8 Klps continous data rate on Win OS. Additional it adds two digital inputs to store two external status signals together with the NMOS data. This makes the analysis of the data a lot easier.

Additional the two external trigger inputs can be used to store the NMOS data at four different locations in the data stream.

Two alternating read/write segments of up to 1024 scans of 512 pixels each ensure there is no missing data.

Mounting is compatible to the Hamamatsu C70xxx heads and the Thorlabs 60 mm Cage System.
