1. Part Numbers and Descriptions Description Mega FINNTM with Sleeve Mega FINNTM sensor 2. Principal of Operation The Mega FINNTM combines the form factor of the Ultra FINNTM with a new operating program that allows for greater speed and stability, to accommodate the need for even faster test measurements and additional types of light sources such as pulsing LEDs. The Mega FINNTM incorporates a light-toFrequency converter sensor with a microprocessor designed to take precise measurements from the sensor. The Mega FINNTM calculates the color and intensity of the light being tested, converting...

5. Features ▪ High accuracy of +/- 0.3% and average resolution of 0.1nm across the visible spectrum ▪ Fast response time – typically less than 3 milliseconds for average to bright LEDs ▪ Works with any Pulse Width Modulation LED pulsing at 50Hz or greater. Worst case response time ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ for PWM LEDs is ~80ms So fast it will output ON and OFF results when an LED is blinking slower than 30Hz Shut off time to dark output is 16ms Intelligent Triggering feature will start a fresh sample when an LED turn on is detected giving this sensor the fastest response time possible Built in InfraRed...

Power Source The Mega FINNTM requires 5.0 volts DC. Current is typically 17 mA. Three pins are: Output (signal), Ground, and Power Pins are spaced 70 mil apart Sleeve uses standard 16 mil square posts for wire wrapping, 30 gauge wire is recommended. Smaller gauge or thicker wire may cause undue stress on the wire wrap posts. Light- to- frequency converter sensor comprised of an 8 x 8 array of photodiodes, 16 photo-diodes each of blue, green and red filters and 16 photo-diodes of clear, with no filter. The micro controller, in combination with the precision MHz high frequency clock source, allows...

8. Mega FINNTM Timing Mega FINNTM response is typically less than 3 milliseconds. The response time will decrease for brighter LEDs and will increase for dimmer LEDs. 9. Fixturing Instructions The Mega FINNTM sleeve is easy to insert into most materials used in fixturing today. Installation Instructions

Stack Up Measurements for Mega FINNTM Troubleshooting Wiring

10.1. Wiring Special care should be paid to the wiring instructions. Improper wiring will result in over-heating and damage to the part. If miss-wiring has occurred, immediate replacement of the damaged part is recommended. 10.2. Ambient light and adjacent LED’s Light from sources other than the device being tested should be prevented from reaching the sensor surface while making measurements. Ambient light entering the sensor’s active area will be used to calculate the color and intensity. Typically the ambient light is many orders of magnitude less than the LED and ambient light will have little...

11. Absolute Maximum Ratings Over operating free-air temperature range (unless otherwise noted)† Supply voltage, VDD (see Note 1) Operating free-air temperature range, TA Storage temperature range Maximum current or output † Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability....
