SpotOptics 公司的Lentino 系统是基于夏克-哈特曼(Shack-Hartmann )原理的新一代波前测试系统，是非球面镜和数码相机镜头质量控制的完整解决方案。直径0.5mm到20mm的光学元件都可测试，并且具有手动、自动调像差校功能。Lentino 测试系统被数码相机制造商Pentax公司用于Optio series 数码相机的质量检测。
可满足不同波长范围的检测需要：- 390 nm -1100 nm (Vis)
- 900 nm-1700 nm (NIR)
-
125 nm-1100 nm (UV)

- 70 Zernike aberration terms
- 3 types of Zernike (Standard, Fringe, Annular) and Seidel polynomials can be fit to the data
- Average of images, coefficients and wavefront to reduce noise
-
Automatic computation of optical quality for three cases:
-
(i) tilt or tilt & defocus removed;
(ii) 7 Zernike terms removed;
(iii) user-selected Zernike aberrations removed - Analysis in real-time (2D and 3D wavefront, Zernike aberrations, spot diagram, residuals)
- On-line optical alignment of complex optical systems
- On-line adjustment of spacing between optical elements
- MTF, PSF, EE (optional)
- Over 50 graphs to help you interpret the results
- Output in Text as well as Excel format
- Creation of test report
Lentino 技术指标 阅读:4891Feature Specification No of spots with standard camera 30 x 30 Maximum no. of spots (large camera) 100 x 100 Maximum diameter that can be tested 20 mm Repeatability of measurements of the Zernike polynomials λ/300 Repeatability of wavefront measurements λ/200 Accuracy About λ/10 Absolute precision Depends on the type of optical element. Typically λ/10 for spherical surfaces Tilt measurement accuracy (angle, depends on the size of optical element) 4ad Wavelength range 0.35 -1.1 Dynamic range of measurements by sub-pupil (tilt subtracted, depends from combination of aberrations) ~ ± 50 λ Asphericity range About 15% variation in LSA (longitudinal spherical aberration) Acquisition speed (standard camera). Faster speeds available on request 4 Hz Mounting option Can be mounted vertically or horizontally Mounting of optical elements Optical system to be tested easily mounted on central mounting slide Easy access to optical elements Access to the mounting plate of Lentino is from the front of the instrument Dimensions (L x W x H) 22 x 20 x 60 cm Weight(approximate) 15 Kg Input voltage (for motor movement) Power supply 500 mA, 9 V
