有两种型号以适合不同波长使用 0.4 μ to 1.1 μ and NIR 0.9 μ to 1.7 μ

Laserino-Pro-Vis

Wavefront sensor with fixed collimator that can be used in external illumination mode in white-light or laser
Two uncooled cameras allow the complete control of laser beam: the first camera is used for wavefront analysis , the second camera for imaging beam-profile of laser
Front flange allows easy mounting and dismounting of lenses and collimators
Standard sampling: 30 x 30 spots
For testing lasers from 0.4 μ to 1.1 μ
Φ max=6.7mm (without beam-expander)
Φ max=58.0mm (with BE60)

Laserino-ProIR

Wavefront sensor that can be used in external illumination mode with laser
One uncooled Lead oxysulfide Vidicon camera can be switched from wavefront analysis to beam-profiler to get a complete picture of the laser beam
Front flange allows easy mounting and dismounting of lenses and collimators
Maximum sampling: 20 x 20 spots
For testing lasers from 0.4 μ to 1.8 μ; optimized in the wavelength range:
0.7 μ to 1.8 μ
Φ max = 8.0 mm (without beam-expander)
Φ max = 58.0 mm (with BE60)

Sensoft: The wavefront sensor based instrument comes with Sensoft Laserino, the Shack-Hartmann wavefront sensor control and analysis software optimized for laser. The package is available under any Windows operating system (2000/XP).

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
