Telecentric Lenses replace fixed focal length lenses.
Press Release Summary:
Series TML(TM) Measuring Lenses correct perspective errors that yield variations in magnification through depth of field. Each lens has front filter thread for color filters, polarizers, and protective windows. Primary magnifications of 0.6, 0.4, 0.25, and 0.16 X are available with fixed working distances from 100-170 mm. Suited for CCD cameras or smaller, each model features telecentricity of less than 0.1° and less than 0.3% distortion.
Original Press Release:
Edmund Optics Offers Newly-designed TML(TM) Telecentric Lenses
November 30, 2003, Barrington, NJ - Edmund Optics, Inc. (EO) of Barrington, New Jersey is proud to present EO designed and manufactured Telecentric Measuring Lenses. This new line of TML(tm) lenses offer a compact, cost-effective solution for replacing standard fixed focal length lenses. Telecentric lenses are ideal for both on-line and off-line production environments that require accurate measurements. Edmund has designed this series of lenses to specifically replace lenses that give inaccurate or inconsistent readings in gauging applications. Telecentric lenses correct perspective errors that yield variations in magnification through the depth of field.
The TML(tm) lenses offer superior image quality and less distortion than conventional fixed focal length lenses. The telecentric design yields more symmetrical images that are superior for software-integrated measurements. In combination with the high quality optics is a simplified non-focusing mechanical design with adjustable iris control (F6 to closed).
Telecentric designs require larger objective lenses in order to maximize the size of the object viewed for each magnification, thus the mechanical housing has been streamlined to accommodate the larger optics and to provide a reasonable amount of mounting surface. Each lens also has a standard front filter thread for use with EO supplied color filters, polarizers, protective windows, and illumination adapters for LED or fiber optic ring guides. Unique twin-ring mounting clamps are available separately.
Primary magnifications of 0.6X, 0.4X, 0.25X, and 0.16X are available with fixed working distances varying from 100mm to 170mm. Each model features telecentricity < 0.1 degree and <0.3% distortion. The TMLs(tm) are designed for CCD cameras or smaller, and each lens in the assembly features a broadband antireflection coating covering 425-675nm.
