When should I replace the Argon-Neon lamp in my Shelyak spectrograph?
You should replace your Argon-Neon lamp when you notice that your calibration frames require significantly longer exposure times to achieve a good signal, or if the lamp fails to ignite entirely. A dimming lamp can compromise the accuracy of your wavelength calibration, so proactive replacement is recommended for critical research.
Are these Argon-Neon lamps compatible with the LHIRES III spectrograph?
Yes, these are the correct OEM replacement lamps for the Shelyak LHIRES III spectrograph's calibration module. They provide the necessary Argon and Neon emission lines for accurate calibration across its high-resolution range.
What is the purpose of an Argon-Neon lamp in an Alpy 600?
In the Alpy 600, the Argon-Neon lamp serves as a precise wavelength reference. 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.
How do I verify a new Argon-Neon lamp is working with Demetra software?
After 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.
Is any special handling required for these Argon-Neon lamps?
These lamps are glass ampoules and should be handled with care to avoid breakage. While the gas inside is inert and not harmful in these small quantities, the primary concern is the fragile nature of the glass. Always refer to your specific spectrograph's manual (e.g., Alpy, LHIRES III) for detailed installation instructions.
Are these lamps compatible with the Shelyak UVEX spectrograph?
Yes, the vendor catalog confirms that these Argon-Neon lamps are compatible with the Shelyak UVEX spectrograph's calibration module. They serve as the primary reference source for wavelength calibration with this instrument.
