Variable Magnification

Wide telecentric "magnification" range from 0.5x to 1.0x, 0.3x to 1.0x for macro-use

FA-Series: Telecentric

Kowa has added a new 4/3 inch telecentric macro zoom to its product line. The LM1119TC is telecentric from 0.5× – 1.0× magnification and able to resolve up to 21 megapixel.

Besides that, Kowa introduces a new 2/3 inch telecentric 5 megapixel plus series. The series includes three lenses with adjustable magnification. The ranges of magnification are 1.725× – 2.2× (LM1121TC), 1.15× – 1.47× (LM1122TC) and 0.69× – 0.88× (LM1123TC).

All new telecentric lenses have very low distortion. They produce high contrast and resolution in both center and corners.

In a telecentric optical system, there is no change in magnification when focusing, and magnification is constant over working distances. Thus movement of an object does not change magnification. Therefore, it is suitable for measuring objects with high accuracy.

• Telecentric lens with variable magnification

• Able to adjust the magnification to match with the pixel size of the camera

• Lenses are designed with an optical magnification that is ideal for over 5 megapixels

• Distortion free lenses of less than 0.02%. TV distortion is limited to 0.25% on the entire image area even when used with a 5 megapixel camera
