The instrument is multifunctional, compact, easy-to-use and reliable.<\/span><\/p><p><span style=\"color: #000000;\">In the Additive Dispersion Mode MSA-130 operates as a standard double additive monochromator (effective focal length is 260 nm) with extremely low stray light provided by its intermediate slit.<\/span><\/p><p><span style=\"color: #000000;\">In the Subtractive Dispersion Mode MSA-130 operates as a tunable filter with adjustable band pass and sharp edge. A width of selected spectral range is set by the intermediate slit, and the central wavelength is set by synchronous turning of two identical diffraction gratings.<\/span><\/p><p><span style=\"color: #000000;\">Since in the Subtractive Dispersion mode the beam path in the second half of the double monochromator conforms completely to the reverse beam path in the first half; the result is the full compensation of dispersions, and the zero dispersion is achieved. The whole spectrum selected by the intermediate slit is imaged at the second monochromator\u2019s output as a spatial line.<\/span><\/p><p><span style=\"color: #000000;\">The MSA-130 is equipped with choice of ruled gratings to suit the application. To ensure perfect dispersion compensation (zero dispersion), the manufacturer takes special care that diffraction gratings of both monochromator halves were replicas made of the same matrix.<\/span><\/p><p><span style=\"color: #000000;\">DESIGN FEATURES<\/span><\/p><p><span style=\"color: #000000;\">The MSA-130 entrance, intermediate and exit slits have manual control and smooth micrometrical adjustment of the opening width. Entrance and exit slits are placed at an angle of 66\u00b0 to the vertical.<\/span><\/p><p><span style=\"color: #000000;\">\u00a0<\/span><\/p><p><span style=\"color: #000000;\">Both the MSA-130 gratings are located at the same axis and are driven by the same step motor. This allows ensuring complete synchronism of gratings\u2019 rotation and high precision of wavelength setting. The MSA-130 gratings are computer controlled via the USB interface.<\/span><\/p><p><span style=\"color: #000000;\"><img decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/www.anjun.com.tw\/wp-content\/uploads\/2019\/01\/3-1-300x235.png\" \/><\/span><\/p><p><span style=\"color: #000000;\">In terms of design, the gratings are fixed in one holder, which is carefully aligned by our service-engineers. The holder with a working set of gratings is installed into the device. At your choice, the MSA-130 may be supplied with one or more additional sets of gratings in holders.<\/span><\/p><p><span style=\"color: #000000;\">Replacement of diffraction gratings in the MSA-130 is easy and fast (see the figure).<\/span><\/p><p><span style=\"color: #000000;\">To replace gratings it is enough to open a cover at the MSA-130 rear panel, unscrew two mounting screws and withdraw the holder with gratings. The holder is placed into a special box from the Spare Parts Kit. A new set of gratings is installed into the MSA-130 housing and fixed with two screws. This procedure is sufficient to perfectly reproduce the position of gratings corresponding to the manufacturer\u2019s calibration.<\/span><\/p><p><span style=\"color: #000000;\">The MSA-130 delivery set includes a viewing unit Sight, which is used to check the current monochromator calibration by the user. The Sight contains an achromatic objective; it is placed on the entrance slit and is used to visually observe positions of the known spectral lines relative to the centre of exit slit. The spectral range of the Sight operation is 200nm-2000nm.<\/span><\/p><p><span style=\"color: #000000;\"><img decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/www.anjun.com.tw\/wp-content\/uploads\/2019\/01\/sight3-300x225.jpg\" \/><\/span><\/p><p><span style=\"color: #000000;\">The software of the MSA-130 monochromator provides possibility of real-time correction of factory calibration by the user.<\/span><\/p><p><span style=\"color: #000000;\">The software also allows calculating the line width selected by the MSA-130 in the Additive Dispersion and Subtractive Dispersion modes depending on the set width of entrance, intermediate and exit slits.<\/span><\/p><p><span style=\"color: #000000;\">The MSA-130 exit slit contains two mounting holes M2.5 that allow fixing your own detector to the slit housing, if necessary. Two additional holes M3 are located on the housing close to the slit unit. Location of mounting holes is shown in the figure.<\/span><\/p><p style=\"text-align: left;\"><span style=\"color: #000000;\"><em>Note: To avoid a breakdown of the slit mechanism it is prohibited to fix any units weighing more than 1kg to the slit housing!<img decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/www.anjun.com.tw\/wp-content\/uploads\/2019\/01\/6.png\"

When the MSA-130 is switched to the Additive Dispersion mode, one of these flat mirrors is interchanged by a roof mirror, i.e. a reflector made of two mirrors that form an angle of 90\u00b0.<\/span><\/p><p><span style=\"color: #000000;\">Mode switching is achieved by a simple turn of the two-position Mode Switch within the same monochromator design. Thus, the MSA-130 ensures operating multifunctionality, while being compact, rigid and stable.<\/span><\/p><p><span style=\"color: #000000;\">All the optical elements in the MSA-130 are carefully aligned by the manufacturer and do not require any additional re-alignments either at switching the operation modes, or at replacement of gratings\u2019 set.<\/span><\/p><p><span style=\"color: #000000;\"><strong>*The MSA-130 optical bench is patented.<\/strong><\/span><\/p><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/section><section data-id=\"39ca2e9a\" data-element_type=\"section\"><div><div><div data-id=\"4bc94fbe\" data-element_type=\"column\"><div><div><div data-id=\"15166f6d\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\"><div><p>\u00a0<\/p><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/section><\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-9c7b377 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"9c7b377\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-89032fc\" data-id=\"89032fc\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-bc71e55 elementor-widget elementor-widget-spacer\" data-id=\"bc71e55\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-59025ce elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"59025ce\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-a1aa985\" data-id=\"a1aa985\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-b91efe8 elementor-widget elementor-widget-text-editor\" data-id=\"b91efe8\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p style=\"text-align: center;\">SOLARLS\u7684\u6240\u6709\u8cc7\u8a0a\u4f86\u81eaSOLARLS\u7db2\u9801\uff0c\u6240\u6709\u7248\u6b0a\u6b78SOLARLS\uff0c\u7e41\u9ad4\u5b57\u7248\u6b0a\u5c6c\u5b89\u5747\u79d1\u6280\u3002<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>Model MSA-130 DESCRIPTION SPECIFICATIONS OPTIONS &amp; &hellip;&nbsp;<a href=\"https:\/\/www.anjun.com.tw\/en\/%e9%9b%b7%e5%b0%84\/%e9%9b%b7%e5%b0%84%e9%80%b1%e9%82%8a%e8%a8%ad%e5%82%99%e9%8a%b7%e5%94%ae\/solar-ls%e9%9b%b7%e5%b0%84\/spectral-instruments\/monochromators-spectrographs\/double-additive-subtractive-monochromator\/\" class=\"\" rel=\"bookmark\">Read More &raquo;<span class=\"screen-reader-text\">DOUBLE ADDITIVE\/SUBTRACTIVE MONOCHROMATOR<\/span><\/a><\/p>","protected":false},"author":2,"featured_media":0,"parent":949,"menu_order":21,"comment_status":"closed","ping_status":"closed","template":"","meta":{"neve_meta_sidebar":"","neve_meta_container":"","neve_meta_enable_content_width":"off","neve_meta_content_width":70,"neve_meta_title_alignment":"","neve_meta_author_avatar":"","neve_post_elements_order":"","neve_meta_disable_header":"","neve_meta_disable_footer":"","neve_meta_disable_title":"","footnotes":""},"class_list":["post-1049","page","type-page","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.0 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>DOUBLE ADDITIVE\/SUBTRACTIVE MONOCHROMATOR &#060; \u5b89\u5747\u79d1\u6280\u6709\u9650\u516c\u53f8<\/title>\n<meta name=\"description\" content=\"The MSA-130 is a compact double monochromator with enhanced functionality and low stray light.
