Overview
The Isolight Puck light and color sensor is an ideal companion for image quality testing or camera calibration systems. No matter your scene size, the Puck lets you quickly measure and verify your lighting color, light level, and uniformity.
The Puck is compact enough to fit in small areas or be embedded in a scene. By arranging multiple Pucks into a group, you can measure lighting brightness and color uniformity across any size test chart.
The Puck connects to your host computer and is compatible with Windows, Mac, and Linux systems. Controlled through a simple serial-over-USB protocol, the Puck is easy to integrate into your test software.
Each Puck comes with a 3m (10 ft) mini-B USB cable and velvet storage pouch.

To aid your development, we have developed MATLAB and Python3 drivers for the Puck. While these drivers are not ready for release, we are looking for beta testers. If you are interested, please contact us.
Feature Highlights
LED Indicator and Programmable Alarms
The full-color RGB LED ring can be programmed to alert you to any lighting condition. Sixteen prioritized alarms can be set to monitor lighting level, color temperature or CIE-xy coordinates. Choose from:
- Four variables – luminance in lux, color temperature (K), CIE-x, or CIE-y coordinates
- 20 test conditions, including greater than, less than, equal, or within range
- Eight LED colors – white, red, orange, yellow, green, cyan, blue, or magenta
- Three LED patterns – solid, flash, or spin
Mounting Options
Mount the Puck quickly and securely to light booth walls or white boards with the rear magnet. The 1/4″-20 thread allows tripod mounting for placing the Puck in scenes or mounting on optical set-ups.
