Edmund Optics (EO) has expanded its line of Techspec imaging and machine-vision lenses.

The company has added more than 30 EO-designed and -manufactured lenses, including Techspec fixed focal length and telecentric lenses, to its catalogue and website.

These new lenses will be showcased at the Vision Show, which is scheduled to take place in November 2009 in Stuttgart (Hall 4, Booth A15).

The expanded offerings include four different product lines: Techspec Compact Fixed Focal Length lenses; Techspec Compact Telecentrics; Techspec Large Format Telecentrics; and Techspec High Resolution Telecentrics.

EO also offers customised solutions for those with special application needs.

The EO Techspec Compact Fixed Focal Length lenses are designed with the working distance and resolution requirements of factory automation and inspection in mind.

The lenses support imaging sensors as large as 2-3in and are available in focal lengths of 8.5mm, 12mm, 16mm, 25mm and 35mm.

A broadband anti-reflective coating offers improved light transmission, making these lenses suitable for restrictive lighting conditions, according to the company.

Telecentric lenses offer low distortion and distance-independent magnification, making them suitable for metrology and gauging applications in machine-vision applications.

The Techspec Compact Telecentrics offer 65mm and 110mm working distances at magnifications ranging from 0.5x to 4x.

The Techspec Large Format Telecentrics support sensors up to 28.7mm diagonal with 4M-pixel resolution and come in a variety of magnifications and camera mount styles.

The Techspec High Resolution Telecentrics support sensors as large as 2-3in with 5M-pixel resolution and come in 0.28x, 0.5x, 0.9x and 1.7x magnifications.
