Computar A Series Eliminates Purple Fringe

3 Megapixel "A Series" Lenses Engineered for Superior Lighting Correction

November 7, 2012, Commack, NY – Computar’s A Series, the industry's first 1/2.7" 3 Megapixel Varifocal IR lenses were engineered for compatibility with the most common 1/2.7" and 1/3” Megapixel camera sensors. The unique optical design assures optimal performance with HD Megapixel camera applications and are available in Manual, DC Auto-Iris and P-Iris models.

  • Purple Fringe Correction – The precise engineering of lens elements and the unique optical design eliminates the chromatic aberration known as “Purple Fringe” - especially in strong backlight situations.
  • 3 Megapixel Varifocal - Designed to capture precise detail in critical security applications. High quality optics maximizes performance with 3 megapixel camera sensors.
  • Full HD Format - By enlarging the image circle design, this series is fully compatible with 720p and 1080p 16:9 format image sensors as well as the standard format 4:3 sensors.
  • Precise Focus Adjustment - The focus mechanism has been redesigned to allow more precise focus control. The focus ring rotates a full 180 degrees allowing enhanced fine-tuning.
  • IR Corrected Optics - Designed specifically for true day/night cameras to deliver HD Megapixel resolution in both day and night modes even with IR illumination of up to 950nm.
  • P-Iris – Advanced iris control technology allowing selection of best quality or best depth of field while delivering the highest sensitivity to suit your application.

“Computar has engineered this lens in its earliest optical design stages to prevent the chromatic aberration known as purple fringe. With the increasing use of HD surveillance, the elimination of this issue has become critical” according to Nick Kushiro, Product Manager, Computar Optics.
