Calibration Target Micro with honing angle is the latest addition to Opto's portfolio of calibration targets and object micrometers

POSTED 07/13/2020

Optical calibration and resolution testing are critical metrics in understanding and optimizing any optical system

Calibration target Micro with honing angle

Calibration Target Micro with honing angle is now available for our customers. The honing angle is DKD-certified.

In contrast to the Target Micro V1, the Calibration Target Mico with honing angle in the 4th quadrant contains a 30° honing angle incl. certificate.

The target contains the following defined structures:

1. 10 lp/mm to 1000 lp/mm

2. Ø20 μm dot matrix 40x40 dots, 100 μm grid

3. positive, negative dots and Siemens star

4. honing angle 30° with certificate

5. scale with steps up to 10 μm

Opto's bestseller and most important calibration target is Calibration Target Micro V1

Calibration Target Micro V1 is unique in that it combines very useful resolution data, combined with ultra-high definition micro features, together enabling efficient and accurate optimization of any optical setup.

 • Ultra-high definition micro features, compatible to the most demanding optical calibration requirements

 • Four unique quadrants combining resolution targets to measurement scales

• Optional with DKD-certificate

The target contains defined structures in different shapes and sizes for easy system calibration and distortion detection.

  1. 10 lp/mm to 1000 lp/mm

  2. Ø20 μm dot matrix 40x40 dots,100 μm grid

  3. Contrast and Siemens structure

  4. Ø10 μm dot matrix 40x40 dots, 50 μm grid

  5. Scale with steps down to 10 μm

Resolution Test Target

Test targets (also called test charts, test samples or resolution test patterns) are used to determine the efficiency of optical systems. They are used to determine resolution, MTF, depth of field, distortion and telecentricity.

It is necessary to test and calibrate every single system for comparative measurements, especially when dealing with several measuring systems of the same type.
