Opto Diode Introduces New, Blue/Green Enhanced Silicon Photodiode Preamplifier

October 23, 2008 - Newbury Park, CA - Opto Diode Corporation, a global supplier of advanced performance photodiodes and highly reliable, visible and IR LEDs, introduces the new, 6 mm² Photodiode-Preamplifier ODA-6WB-500M. Featuring extremely low noise, high sensitivity and a large active area, the newest combination device is the third in the family of blue/green enhanced photodiode-preamplifiers. With sensitivity response at 450 nm, typically 140 V/µW (min. 100), the detector operates between 400 nm and 1100 nm, with peak spectral frequency at 940 nm. The ODA-6WB-500M features a transimpedance gain of 500 Mohm, with custom gains also available upon customer request. Opto Diode's preamp combo is ideal for fluorescence detection and low-light-level medical diagnostic applications.

Hermetically sealed in a standard TO-39 housing, the new photodetector-preamplifier combo is easy to integrate into your current system or can be quickly adapted to a custom configuration. Storage and operating temperatures range from minus 25 degrees to 100 degrees C and withstand a soldering temperature (1/16 inch from the case for 3 seconds maximum) up to 260 degrees C. The new blue enhanced detector preamps are affordably priced at $44.80 in quantities of 100 units.
