Power is supplied via two separate 12V inputs using standard 5.5\/2.5mm center-positive connectors, allowing for independent, automated control of your entire calibration sequence from a remote location.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eAutomated Flats and Wavelength Calibration for the LISA\u003c\/h3\u003e\n\u003cp\u003eThis single module provides both sources required for professional-grade spectroscopic calibration. The internal halogen lamp produces a uniform, continuous spectrum, allowing you to create flat-field frames that correct for dust, vignetting, and pixel-to-pixel variations in your imaging sensor. The Argon-Neon (Ar-Ne) lamp produces a spectrum with well-defined emission lines at known wavelengths, providing the precise reference needed to accurately calibrate your data's wavelength scale.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eDesigned for Remote Observatories with Dual 12V Inputs\u003c\/h3\u003e\n\u003cp\u003eThe key advantage of the LISA Calibration Module is its suitability for remote, unattended operation. It features two distinct 12V DC inputs, one for each lamp, enabling you to connect them to a relay box or switched power supply. This separation allows your automation software to trigger each lamp independently, running a full calibration routine—flats and wavelength references—without any manual intervention at the telescope.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat is the purpose of the two lamps in the LISA calibration module?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe LISA calibration module contains two essential lamps for spectroscopy. The \u003cstrong\u003ehalogen lamp\u003c\/strong\u003e provides a smooth, continuous light source for taking flat-field frames, which correct for optical imperfections and sensor variations. The \u003cstrong\u003eArgon-Neon (Ar-Ne) lamp\u003c\/strong\u003e produces a spectrum with sharp, known emission lines, used to accurately calibrate the wavelength scale of your scientific data.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow does the LISA calibration module enable remote observations?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe module features two separate 12V power inputs, one for each lamp. This allows you to connect each lamp to an independent channel on a remote power switch or relay box. Your observatory automation software can then turn each lamp on and off in sequence to acquire calibration frames without you needing to be physically present at the telescope.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eDo I need two separate power outputs for the LISA calibration module?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes, for automated remote operation, you need two independently switchable 12V DC outputs. This allows your software to trigger the halogen lamp for flats and the Ar-Ne lamp for wavelength calibration as separate steps in a sequence. Using a single output would require you to manually swap the power cable between inputs.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat kind of power supply do I need for the LISA calibration module?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYou will need a 12V DC power source capable of supplying two outputs. The connectors on the module are 5.5 \/ 2.5mm barrel jacks with a center-positive polarity. These are common connectors for astronomical equipment, but power supplies are not included.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eIf I'm studying the spectrum of Vega (Alpha Lyrae) with my C11 and LISA, how do I use the LISA calibration module?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eIn a typical workflow, after acquiring the spectrum of Vega, you would use automation software to trigger the LISA calibration module. First, it would turn on the halogen lamp to take several flat-field frames. Then, it would switch to the Argon-Neon lamp to record a wavelength calibration spectrum. These two calibration files are then used in software like Demetra to process your raw data of Vega into a scientifically accurate spectrum.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhy do I need to take flat frames with my LISA spectroscope?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eFlat frames are crucial for high-precision spectroscopy. They record the response of your entire optical system—including dust on the sensor or slit, and pixel-to-pixel sensitivity variations. By dividing your science image by a master flat, you remove these instrumental artifacts, ensuring that the spectral features you measure are from your astronomical target, not your equipment.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ctable class=\"DAV-specifications\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatibility\u003c\/td\u003e\n\u003ctd\u003eShelyak LISA Spectroscope\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFlat Lamp Type\u003c\/td\u003e\n\u003ctd\u003eHalogen\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCalibration Lamp Type\u003c\/td\u003e\n\u003ctd\u003eArgon-Neon (Ar-Ne)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Input\u003c\/td\u003e\n\u003ctd\u003e2x 12V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnector Type\u003c\/td\u003e\n\u003ctd\u003e5.5 \/ 2.5mm, Center-Positive\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cul class=\"DAV-grid\"\u003e\n\u003cli class=\"DAV-grid-item\"\u003e\n\u003cdiv\u003e\n\u003cp class=\"DAV-item-title\"\u003eLISA Calibration Module\u003c\/p\u003e\n\u003cp class=\"DAV-item-subtitle\"\u003e× 1\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\n\u003cli\u003e\n\u003ca href=\"https:\/\/davidastro.com\/pages\/shelyak-warranty-policy\" rel=\"noopener\" target=\"_blank\"\u003eShelyak 1-Year Warranty\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Shelyak","offers":[{"title":"Default Title","offer_id":52943045755165,"sku":"SHK-SE0103","price":679.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/5280\/1565\/files\/Shelyak-LISA-calibration-module-1_26d9aa25-a5ec-4a83-98d1-77f0001bde3f.jpg?v=1789616277","url":"https:\/\/davidastro.com\/fr\/products\/shelyak-se0103","provider":"David Astro","version":"1.0","type":"link"}
