UPDATE: Lisa and LhiresIII calibration lamp



High SNR and high resolution spectra of a filly lamp, dot model, with lines of argon, xenon and neon inside. It is very usefull to calibrate low and high res spectra specially in the blue domain. I was needing it for my own low resolution spectra work.

Also a spectra of a flame bulb, candle like, not a lot of lines, only neon.(20111211_200329_flamme_60x60s_TGarrel)


Calibatrion is made on thorium argon lines, eshell spectroscope, rms cal is better than 0.01A, Resolution is 10000, exposure time is 120X60s with a ST10XME ccd camera.

Enjoy !

(C.Buil) Dot filly lamp


Update: Two other sources of calibration:

A plasma ball, a mix with neon and argon and lightnings inside. A lack of lines in the middle of optical domain make it not a good source of calibration. But it"s still funny and nice.













A stroboscope xenon projector. Well you usually met this stuff in night clubs. It may be interesting in observatory too with a very rich spectra full of calibrations lines on the whole optical spectrum. 15 euros, a good alternative to the dot filly lamp cause lines are more intense and may be able to illuminate the full aperture of the telescope.

Note: a continnum is present in this lamp and lines are quite large.

Lhires III , LISA neon bulb:

Orders 28 to 53, in relative intensity. Note blue lines of the neon are very weak compare to red ones, from a factor 100 or more !
