Sensor merges spectrophotometer with in-line vision

Legend Spectral Camera ultra-sensitive color SmartImage sensors from DVT Corp. merges the color sensitivity of a spectrophotometer with an in-line vision sensor. This makes it ideal for the most demanding color applications in which small color variations are critical, such as inspecting individual parts in an automobile door, where one model may have several variations of white.

Legend Spectral Camera uses a built-in Spectrograph to split the incoming light into its constituent wavelengths along the X axis and spatially along the Y axis. With this product, the complete spectrum (380nm-900nm) of the sample can be learned, and small deviations detected. The peak location of the spectrum can also be monitored for LED quality control. The system is highly sensitive to color, and has unlimited color learning capabilities.

DVT reports that color recognition is another breakthrough for the firm that has added new levels of flexibility and power to many inspection applications. Until recently, color machine vision systems were expensive, bulky, and complex to implement on the factory floor. DVT adds that its newest SmartImage Sensors are the industry’s first Ethernet-ready vision sensors with color capability. www.dvtsensors.com
