About Sensor Instruments
Sensor Instruments Entwicklungs- und Vertriebs-GmbH was founded in 1992 and specializes in the development and manufacture of optoelectronic sensors and sensor systems. The product portfolio includes True Color color sensors (SPECTRO series), laser sensors for distance, thickness and position measurement (L-LAS series), contrast and edge sensors, gloss and structure sensors, light barriers, UV, NIR, MIR and SWIR sensor technology, fiber optic systems as well as spray jet detection systems. A key focus is on customer-specific complete solutions in which sensor technology, control technology and mechanics are combined into individual metrology systems. The entire product range is manufactured in Germany at the company's headquarters in Thurmansbang in the Bavarian Forest. Customers come from industries such as plastics and textile recycling, the semiconductor, automotive, medical and pharmaceutical industries, mechanical engineering, punch pressing technology, and the food, paper and packaging industries. In addition to its own product range, the company offers service and engineering in the field of sensor systems and metrology.

Processes and Metrology
True Color Color Sensors
Measuring color sensors with a D65-like optical spectrum for inline color measurement and control, among other applications on plastic recyclates.
2-Channel Sensor Systems
Normalized comparison of two wavelength ranges from UV-C to IR-B.
Contrast Sensors
Ultra-fast contrast sensor technology for the UV, VIS and IR ranges, among other things for edge detection on punching strips.
Laser Triangulation Sensors
Distance measurement and positioning as well as laser differential, thickness and position measurement in master/slave configuration.
Gloss Sensors
Contact-free inline gloss measurement from various viewing angles, e.g. on plastic pipes.
Spray Jet Detection Systems
Inline spray jet monitoring, also with fiber optic front-ends of the FIO series.
Frame Light Barriers
Fast, highly sensitive light barriers for counting and triggering the smallest, fast-moving objects.
Edge Detectors
Edge and gap detection, e.g. in punch pressing technology.
Laboratory Measuring Devices and Inline Detectors
Compact handheld devices, laboratory measuring devices and inline detectors for color measurement tasks.
