Note on replacing the grating on p. 20

Blaze Reflection Gratings 1200 L/mm
cemented onto Tilting grating holder
For high resolution observations where the 900 and 1200 gratings are used, Dados (by construction) is expected to provide the best optical performances in a short spectral range (30 nm).
It needs to be pointed out to any prospective user up front that the 1200L grating has been addded later on some customers insisting demand, for projects that concentrate mainly on the H-alpha region – to attain max resolution there. The 1200L grating however cannot show the full spectrum and the tilting range is limited to H-alpha mainly. In case this restriction is not acceptable, this grating ought not to be part of an order.

Important note:

Our Blaze Reflection Gratings with 200, 900 and 1200 lines/mm are only available with proven purchase of a DADOS Spectrograph. Please contact us if you're interested.

Small imperfections are within tolerance

The small dots or supposed scratches shown here (please click on image to enlarge) are not dirt but minimal imperfections in the master grating that are within tolerance and do not degrade the image. An exchange due to this purely cosmetic defect is therefore not possible

This blaze grating replaces the grating supplied with the DADOS spectrograph.

The 200 lines/mm grating is included with the DADOS and serves as a replacement if the original grating is damaged..
The 900 lines/mm grating provides a higher resolution. Due to the design, the best resolution is achieved over a smaller spectral range (30nm).
The 1200 lines/mm grating is made for high-resolution observation of the H-alpha part of the spectrum. Due to its design, it also provides the best resolution over a spectral range of 30 nm. However, it cannot image the entire spectrum and cannot be set to spectral ranges far away from the H-alpha line.

To replace the grating, please refer to the latest instructions for the DADOS spectrograph, which you can find as a PDF under “Downloads”.
