Lenses for high resolution line scan applications

12k lenses for high-resolution linear array
camera sensors

The line scan image capture method is useful and efficient for many web and other surface inspection applications. When choosing an appropriate camera, correct lens selection is vital to achieve the desired system performance.

The size of the linear array sensor in the camera determines the minimum required image circle of the lens and the size of the sensor's pixels determines a particular optical imaging resolution.

The desired object resolution defines the necessary magnification ratio for the optical system. These application specific parameters allow you to choose the most suitable lens to meet all requirements with respect to image size and quality.

Today's high-performance lenses must follow the technology trend toward smaller pixel sizes and increased sensor resolution. This typically results
in larger array sizes and more stringent requirements concerning MTF (Modulation Transfer Function).

More Macro Systems: Makro-System Makro-Varon™

All versions of the ultra high resolution 12k Line Scan lenses Makro-Symmar and Apo-Componon features Schneider's unique iris as well as focus locking mechanism and an overall robust design, to ensure extremely reliable and precise measurements in even the harshest high-vibration manufacturing environments.

To optimize lens performance to highest possible level, all Schneider
12k Line Scan lenses come with the position of "best average azimuth" marked right on the lens body. System manufacturers can compensate for all residual asymmetric tolerances by using this mark to align the lens with the line sensor.

Makro-Symmar 5.6/120

Makro-Symmar lenses are designed for industrial machine vision applications and satisfy even the most stringent requirements of next generation 12k line scan applications.

Makro-Symmar 5.6/120	f-stop range	5.9 - 32

nominal	range		image-dist.
0.33	0.26 – 0.38	118.9 mm	638.1 mm	1004611
0.5	0.38 – 0.63	119.75 mm	538.3 mm	1002650
0.75	0.63 – 0.88	120.4 mm	489.8 mm	1002648
1.0	0.88 – 1.13	120.7 mm	480.9 mm	1002647

Accessories: Helical mount UNIFOC 100

Apo-Componon 4.5/90

The focal length of 90 mm reduces required working distance, which decreases the space required for the camera-lens assembly. This lens allows system designers to make their machines both smaller and more stable, because shorter distance optical assemblies are less sensitive to vibrations and temperature drift.

At f/4.5, the lens speed helps to increases image brightness and reduces system costs associated with illumination assemblies.

Apo-Componon 4.5/90	f-stop range	4.5 – 25.5
	focal length	90.8 mm
	sensor pixel size	9 μm / 5 μm
	magnification range \|ß'\|	0.2 – 0.4
	working distance	362 mm
	object-to-image-dist.	508 mm
	distortion	0.2%
	weight	140 g
	code no.	1004531
