These Argon-Neon lamps produce a distinct and well-documented pattern of emission lines, which software like Demetra uses to create a precise dispersion model for your instrument. This pack of three ensures you can quickly replace a depleted or failed lamp, minimizing downtime and preventing loss of calibration accuracy during an observing run.\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\u003eEssential Spares for Alpy, LISA, and UVEX Spectrographs\u003c\/h3\u003e\n\u003cp\u003eThese Argon-Neon lamps are the official replacement parts for a range of Shelyak spectrographs. They are confirmed to be compatible with the calibration modules for the Alpy series, LHIRES III, LISA, and UVEX instruments.

When you take a calibration image, the spectrograph records the distinct, fixed-wavelength emission lines from the lamp. Software then uses the known positions of these lines to build a mathematical model that assigns a precise wavelength to every pixel on the sensor, which is essential for analyzing your science target's spectrum.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow do I verify a new Argon-Neon lamp is working with Demetra software?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eAfter installing a new Argon-Neon lamp, connect to your spectrograph and take a new calibration exposure in the Demetra software. You should see a bright, clear pattern of sharp emission lines. If the lines are significantly brighter and more distinct than with your previous lamp at the same exposure setting, the new lamp is working correctly.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eIs any special handling required for these Argon-Neon lamps?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThese lamps are glass ampoules and should be handled with care to avoid breakage.
