Notes and explanations for the specifications table:
(1) With the appropriate auxiliary optics, optical elements of almost any diameter can be tested
(2) Lenslets with different diameters available on request
(3) Lenslets with different focal lengths available on request
(4) With the standard CMOS camera (chip size 6.8 x
8.6 mm²). Pixel size: 6.7μ
(5) Depends on the chip size of the camera. In Optino wavefront sensor, the camera is mounted externally, and can be changed easily.
For details, see separate section
(6) Repeatability of measurement obtained by combining 100 SH
images taken in succession. The error of this coefficient
depends on the sampling used for obtaining the SH
image
(7) Repeatability of measurement obtained by combining 100 SH
images taken in succession
(8) This will determine the final accuracy of the measurements, as the SH test is a differential test
(9) Other cameras with an extended range can be used
(10) Other cameras with an extended range can be used
