Product Details
Name: Multifunctional Digital Optical Bench
Model: MTF—1 Model
Usage: This new product is mainly used to measure various performance parameters of optical lenses and evaluate their imaging quality. MTF comprehensively reflects the contrast and resolution characteristics of lens imaging. MTF is measured using instruments, so it can completely eliminate the influence of objective factors such as film and the subjective factors of manual interpretation. It is currently an objective and accurate method for image quality evaluation. The specific contents of the test include:
1. It can be used to compare the differences between the design values and the actual production measurement values of optical lenses;
2. It can be used to verify the differences between the actual values and design values of sample optics;
3. It can be used as a calibration standard for MTF machines on the production line;
4. Test frequency 0～200lp/mm.
Function ality ：
1. MTF Measurement
(1) MTF and spatial frequency; (2) MTF and FOV; (3) MTF and rotation angle; (4) MTF and defocus position
