Spectrographical observations are taken out with the DADOS or the BACHES spectrograph, both manufactured by [[http://www.baader-planetarium.de/dados/dados.htm | Baader Planetarium]]. ====== The DADOS spectrograph ====== [{{ ost:spektrograph:dados:spektrograph_klein.jpg?295| Our DADOS spectrograph }}] The basic data are partly taken from the Baader webpage. ^ Grating ^ Dispersion at 550nm ^^ Spectral resolution $\frac{\lambda}{\Delta\lambda}$ at 550nm with the 3 slit widths ^^^ Covered Spectral range in nm ^^^ | Line/mm | nm/mm | nm/9µm Pixel | 25µm | 35µm | 50µm | ST-7 | ST-8 | STF-8300 | | 200 | 47,61 | 0,428 | 543 | 388 | 272 | 328 | 656 | 855 | | 900 | 12,67 | 0,114 | 3818 | 2727 | 1909 | 87 | 174 | 227 | Representative spectra that where taken with our DADOS spectrograph can be found [[en:ost:spektrograph:aufnahmen|here]]. ==== Manual ==== /* [[http://www.baader-planetarium.de/dados/download/dados_manual_english.pdf | User's Guide (PDF)]] */ A User's Guide, next to other helpful documents, can be found [[http://www.baader-planetarium.com/en/baader-dados-slit-%E2%80%93-spectrograph.html | here]]. \\ \\ ====== The BACHES echelle spectrograph ====== [{{ :ost:spektrograph:baches:baches_st-8.jpg?295| Our new BACHES spectrograph }}] The new echelle spectrograph from Baader Panetarium, which has been developed by the Max-Planck-Institut for extraterrestrial physics, has the following properties: * Resolution: $R = \frac{\lambda}{\Delta \lambda} = 14,000-20,000$ * Wavelength range: $\lambda$ = 400-700 nm (without gaps) * maximum efficiency: 31% ==== Manual ==== The [[ http://www.baader-planetarium.com/en/baches-echelle-spectrograph.html | Baader Product Page]] provides helpfull documents like the manual or the calibration instructions. /* [[http://www.baader-planetarium.de/baches/download/baches_manual_e.pdf | User's Guide (PDF)]] [[http://www.baader-planetarium.de/news/baches/baches_english.htm | Baader Product page]] ==== Calibration ==== [[http://www.baader-planetarium.de/baches/download/midas_manual.pdf | Calibration manual]] */ en/ost/spektrograph/grunddaten.txt Last modified: 2022/03/16 14:36by fruenger
