Product News for luminance contrast
DIGITAL RADIOMETER WITH LUMINANCE SENSOR
The Gould-Bass DLM-1500 Digital Radiometer is a portable, 3-1/2 digit instrument that measures a spectral range of 380-700 nanometers both in luminance and in Footlamberts, or illuminance (photopic response) in your choice of Footcandles or Lux (read more)
Reflections on Reflections
Reflections from a display are a fact of life. By careful design of the display and installation, it is possible to produce a display with adequate luminance and contrast (for both specular and diffuse reflections) to allow the user to comfortably read the display and take action on the data so obtained.

Enhancements to Color and Contrast Sensors
KT10-2
The KT10-2 is the next generation of the KT10 Contrast Sensor. The KT10-2 maintains the exceptionally high switching frequency of 25 kHz (20 ƒÝsec response time). New features include an easy-to-read bar graph display and 2 light exits. The bar graph display provides visible confirmation of the teach-in and can be used to monitor the sensor's status. The sensor's two in...

Fastest Advanced Contrast Sensor
The CNTX™ combines small spot size and fast response to achieve high-speed contrast differentiation of both neutral and color targets. The sensor provides numerical display of 50 grayscale levels. The broad-spectrum light source allows accurate detection of a wide range of colors against any background. (read more)
High Contrast Compact Display - Starting at $295
Panasonic GT05 series Touch Screen Displays offers increased functionality and image quality over touch screens of similar size. The 3.5 inch GT05 series is available in color and monochrome. The color models support 4096 colors. Monochrome models offer multi color backlighting (White, Red and Pink or Red, Green and Orange). Images on all models are crisp, bright and of high contrast ratio, off... (read more)
Color, Contrast and Luminescence Sensor Selection
Sensor commissioning involves selection of the right sensor to job, installation and evaluation. Many sensors feature a "teach" function. The teach function allows the operator to "teach" the sensor the pass or fail condition by placing a known "good" part in the sensor's field-of-view, pressing a key on the sensor, then placing a "bad" part in the sensor's field-of-view and again ...
