The Aurora Flatfield Panels are mounted in a rigid frame consisting of virtually unbreakable plastic with an extra protection around the edge so your Aurora is very well protected during transport and travel.
The opaque front plate gives you a more uniform brightness than the EL material alone. For very fast optical systems, you will likely need to reduce the brightness by placing some sheets of paper in front of the EL sheet and the frame of the Aurora will keep them secure.
|The light emanating from the Aurora Flatfield Panels is slightly blueish-white.
Most panels from other suppliers seem to provide pure white light (as perceived by the human eye) but the light is in fact made of discrete emission lines. Due to this, the flat field EL panels from most other suppliers are not suitable for narrowband emission line filters.
From Aurora they have tested the products of all EL sheet manufacturers worldwide and selected these particular EL foils for the Aurora Flatfield Panels because they are the best for astronomical applications.
The spectrum of the Aurora Flatfield Panels is not made of some emission lines. Instead, the EL material used in the Aurora Flatfield Panel has a very broad, continuous emission across the whole spectrum.
This fact is what makes the Aurora Flatfield Panels great for narrowband emission line filters.
The three spectra beside illustrate the difference between our continuous spectrum EL panels and typical EL panels with light generated with discrete emission lines present.
The Aurora flats are round in shape, perfect for telescope tubes and the diameters are matched to fit the popular sizes of amateur telescopes. The following sizes are available:
- D 100mm (for Instruments up to 4″)
- D 160mm (for Instruments up to 6″)
- D 220mm (for Instruments up to 8″)
- D 315mm (for Instruments up to 12″)
- D 420mm (for Instruments up to 16″)
(*) Larger Aurora Flatfield Panels up to 60cm are possible upon request. Special custom made foils up to 1.1m diameter are possible also. (Upon special request, contact us at firstname.lastname@example.org).
The Aurora Flatfield Panels packages include a compatible inverter. (Standard AC adapters won’t work.) The panel is illuminated by the external high voltage produced by the inverter. This high voltage, however, is produced at very low amperage, so there is no risk of electric shock.
There are 12V inverters for all sizes of Aurora Flatfield Panels (100mm. also with AA batteries) and for the large size units (315mm. and 420mm.) there are also 110/220V inverters available.
IMPORTANT: Please use the Aurora Flatfield Panels with the supplied matching inverter only. Connecting a panel to an inverter of the wrong size reduces the lifetime of the unit.
Your Aurora Flatfield Panel is shipped as a ready-to-use set:
- mounted EL substrate,
- the matching inverter
- all cables
- printed manual
|We recommend using the panel with the ND “filter sheet”, which allows you to dim the light and have more time to expose the image.|
