Feature SpecificationType of element that can be tested Lasers from 0.4 μ to 1.1 μ with Laserino-ProVis wavefront sensorLasers from 0.9 μ to 1.7 μ with Laserino-ProNIR wavefront sensorOptical elements with external illuminationDiameter of optical element that can be tested(1) Practically any diameterDiameter of lenslets(2) 0.2 mmFocal length of lenslets(3) 22 mm for Laserino-ProVis wavefront sensor, 11 mm for Laserino-ProNIR wavefront sensorStandard sampling on the pupil(4) 30 x 30 spotsMaximum sampling(5) 100 x 100 spots with large format cameraAnalysis Software SensoftRepeatability of measurement of Zernike polynomials(6) < λ/300 rmsRms repeatability of wavefront measurement(7) < λ/200 rmsAbsolute precision(8) Depends on the surface quality of the reference optical element. Typically λ/20 - λ/100Wavelength range (visible camera)(9) 0.375 μ - 1.1 μ with standard cameraWavelength range (IR camera)(10) 0.9 μ - 1.7μTilt measurement accuracy (angle depends on the size of the optical elements) 4 μ radDimensions 9 (H) x 22 (L) x 9 (W) cm.Power requirement (Vis Fiber optic light source) 120V or 220VPower requirement (stepper motor) 12 V, 500 ma.Height of optical axis from base 65.5 mm 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
