Standard E-Series SLM&#8217;s have a phase ripple in the range of 0.1-0.3%. \u00a0Phase ripple is quantified by measuring the 1st order diffracted spot as compared to the mean intensity while writing a blazed phase grating to the SLM.<br \/>\n<strong>Diffraction Efficiency (1st Order)<\/strong><br \/>\nThis is the percentage of light measured in the 1st-order when writing a linear, repeating phase ramp to the SLM as compared to the light in the 0th\u00a0order when no pattern is written to the SLM. \u00a0Diffraction efficiency varies as a function of the number of phase levels in the phase ramp such that as the number of levels \/ ramp decreases, we can gain insight into the efficiency of the SLM. \u00a0Below we show data taken at 1064nm with phase ramps varying from 2 to 16 phase levels between 0 and 2\u03c0.<br \/>\n<strong>Intuitive Software and Development Kits<\/strong><\/p>\n<ul>\n<li>User-friendly software provided<\/li>\n<li>Intuitive image generation and sequencing<\/li>\n<li>Software development kits available for Labview, Matlab, Python and C++<\/li>\n<\/ul>\n<p><strong>Image generation capabilities include:<\/strong><\/p>\n<ul>\n<li>Bessel beams (spiral phase, fork, concentric rings, axicons)<\/li>\n<li>Lens functions (cylindrical, spherical)<\/li>\n<li>Gratings (blazed, sinusoid)<\/li>\n<li>Various diffraction patterns (stripes, checkerboard, solid, random phase)<\/li>\n<li>Holograms<\/li>\n<li>Zernike polynomials<\/li>\n<li>Image superposition<\/li>\n<\/ul>\n<p><img fetchpriority=\"high\" decoding=\"async\" src=\"https:\/\/stagingphotonics.laser2000.co.uk\/wp-content\/uploads\/2024\/07\/19x12-SLM-Efficiency.png\" alt=\"S Series High Speed Spatial Light Modulator Phase stability\" width=\"382\" height=\"271\" \/>\u00a0 \u00a0 \u00a0 \u00a0 <img decoding=\"async\" src=\"https:\/\/stagingphotonics.laser2000.co.uk\/wp-content\/uploads\/2024\/07\/High-Phase-Stability-Standard-Speed-SLM-600.png\" alt=\"S Series High Speed Spatial Light Modulator Diffraction Efficiency\" width=\"431\" height=\"270\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>We offer a wide range of 1920 x 1200 analog spatial light modulators, with varying <strong>wavelength ranges(400-1650 nm)<\/strong>, <strong>LC response time(14.0 -55.0 ms)<\/strong> and <strong>diffraction efficiency (76-98%)<\/strong>.<\/p>\n","protected":false},"featured_media":57872,"template":"","meta":{"_acf_changed":false,"footnotes":""},"product_brand":[],"product_cat":[172],"product_tag":[],"class_list":{"0":"post-57828","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-spatial-light-modulators-polarisation-phase-control","8":"first","9":"instock","10":"shipping-taxable","11":"product-type-variable"},"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.6 (Yoast SEO v27.7) -
