Please note:

Each DADOS spectroscopic grating (especially the 1200 line grating) needs to be precisely calibrated individually for each DADOS-spectrograph. If you order a DADOS together with another of our reflection gratings, this service will be done by us before shipping your order. If you already own a DADOS, we must ask you to return your DADOS each time when you order another grating, apart from the standard 200 line grating. Gratings can be exchanged by yourself later on, if you choose to change the grating resolution. But the initial calibration of the grating in relation to the mechanical body of the DADOS must be one here one time.
You will only pay for the cost of the grating and the transportation. We will do the calibration work free of charge for the Baader 900 and 1200 line gratings. Please announce your order planning well in advance so that we can plan it in production and provide a comfortable time slot.
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.
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).

Important note: our Blaze Reflection Gratings with 200, 900 and 1200 lines/mm (#2458557, -56, 59) are only available with proven purchase of a DADOS Spectrograph and must be calibrated at our company. We ask for your understanding that we have to cancel single orders
